In order to maximise the chances of inter-population and intra-population open-pollination in Populus deltoides, a breeding orchard has been established at Forest Research Institute, Dehra Dun. The orchard will also provide reproductive buds for undertaking control-pollination among promising clones of this species. Seventeen female clones and 25 male clones have been planted in the orchard. Eight outstanding clones, which are yet to manifest their sex, have also been included in the orchard.- Clonal Evaluation of Poplar (Populus deltoides Bartr.) in Eastern Uttar Pradesh.

75 different clones of Populus deltoides were screened in nursery stage under Eastern Indo-Gangetic conditions for recommending suitable clones for large-scale plantation in different Agro-forestry systems. Four commercial clones namely G3, G48, D121 and Udai were treated as check and these were compared with the rest of the clones. Eleven best clones (D121, D124,82-26-5, 34-N, 40-N, 25-N, UD-36, UD-5502, 90-12, UD-6502 and UD-4707) are earmarked on the basis of independent culling methods of selection. Another set of 12 clones were closely followed to the first set of 11 best clones are also graded as potential clones. The field trials of promising clones have already been undertaken for selecting the site matched clones for commercial culture of Poplar in Eastern parts of Uttar Pradesh.- Clonal Evaluation on Poplar (Populus deltoides Bartr.) in Eastern Uttar Pradesh.

Clonal performance of the 50 promising clones of Populus deltoides, developed within and outside the country, has been statistically analysed at one third of the commercial rotation for six growth parameters viz. survival percentage, plant height, diameter, crown diameter, number of branches and volume. Genotypic and phenotypic coefficient of variation, broad sense heritability on individual plant basis, clone means basis and genetic gains have been worked out for all six growth parameters. Higher heritability was observed in diameter than plant height. Maximum heritability was well as genetic gain were obtained in volume. 30.28% expected genetic gain is achieved from selecting the 10% of 50 clones, i.e. 5 best clones namely 40-N, UDH-9116, 25-N, 63-N and UDH-1002.- Flowering Status of Populus deltoides Clones in India

Progress made in India about introduction and further improvement of P. deltoides is reviewed. Out of the hundreds of clones of P. deltoides introduced in India over the past four decades, only 3 to 4 clones (out of which 2 to 3 originated from the same geographical area) are widely grown by farmers in their agroforestry plantations in the plains of western Uttar Pradesh, Haryana and Punjab. In order to undertake multilocation trials ofa greater number of promising clones, 108 clones have been ranked on the basis of their field performance in two trials. Several clones rank higher than G-3 (which is presently one of the most popular clones of this species in India) and they need to be tested in field trials at multiple sites allover the poplar-growing region of the country. Germplasm of P. deltoides presently available in India comes from only about 25 per cent of the native range of this species in the U.S.A. Introduction of more germplasm from wild stands in the U.S.A is suggested. Some clones from open-pollinated progeny of G-48 and G-3 have been developed in the past few years, but open-pollinated progeny cannot be used in long-term breeding programme. Need to start control-pollination work using appropriate mating design has also been emphasised. This review has provided the basis for development of an All-India Coordinated Project for Improvement of Poplar to be executed by Forest Research Institute, Dehra Dun in collaboration with the research units of State Forest Departments and universities.- Improvement of Populus deltoides Bartr.

A coordinated, multi-organisational strategy for research, development and dissemination of improved clones of P. deltoides has been developed and discussed in this paper. The programme has been initiated by research groups of various research institutes, universities and Uttar Pradesh State Forest Department under the technical guidance and coordination of the Chief Technical Advisor (CTA) and Associate CTA for Poplar. The programme envisages carrying out of multilocation clonal trials of promising clones identified to be existing in the country. A breeding programme for control pollination ofthe promising clones using 4 × 4 assortative mating design has also been launched. Seed from 104 candidate plus trees of P. deltoides from 44 wild stands in 11 States of South-eastern USA has been obtained in pursuit of this strategy. Clones will be developed at FRI from the seeds of control pollination and introduction from the U.S.A. These clones will also be tested at multiple sites under the All-India Coordinated Poplar Improvement Programme. A 10-year action for FRI and all other coordinating research units has also been prepared.- Variability, Heritability and Genetic Gain of some Growth Characters in Bambusa balcooa

To study variability, heritability and genetic advance in Bambusa balcooa, culm height, culm girth and number of new shoots were recorded at four different age groups from vegetatively propagated six plus bamboo (clump/ genotypes) selected in different areas of Arunachal Pradesh and Assam. Significant variation was obtained in plant height and number of new shoots in all four successive ages. High heritability accompanied with high genetic advance for plant height and number of new shoots provide clear cut index of these characters in selection, improvement and multiplication for higher yield of biomass.- Effect of Different Factors on the Success of Tender Shoot Cleft Grafting in Chilgoza (Pinus gerardiana Wall)

Four factors, namely time of grafting, age of clone, age of ischolar_main-stock, and age of scion, have direct bearing on the success of tender-shoot-cleft-grafting on Chilgoza. February is the best period which gives 65-70% success, followed by medium-size of tree (less than one metre girth), two and half years old ischolar_main-stock and two years old scion.- Propagation, Selection And Establishment of Clonal Seed Orchard of Chilgoza Pine (Pinus gerardiana Wall.)

Clonal propagation was standardized in Chilgoza pine. 20 plus trees were selected from 15 different places of Kinnaur in Himachal Pradesh. Information on variability, heritability and expected genetic gain (genetic advance as percent of mean) were obtained for eight cone and nut characters. In general, heritability estimates were quite high for most of the characters. Seed weight per cone provides lot of variability, high heritability and maximum genetic gain 29.47 followed by seed length and number of seeds per cone, Seed weight per cone should be given top priority for selecting the high yielding genotypes.

There are about 3000 species of flowering plants in Arunachal Pradesh and out of these. About 700 species of forest plants are of economic importance. Observations on flowering, fruiting. Germination period and per cent, plant per cent, viability period, weight of seed/fruit and number of seedlings obtained from seeds/fruits of known weight of important species including bamboo and cane were recorded on the basis of trials conducted from 1978 to 1986. These informations will be of much use for the field foresters to collect required quantity of seed/fruit timely. The germination per cent worked out in laboratories are of very litlle use to the fieldman. Under laboratory condition germination per cent of a species may be 90% but under field condition it can be less than 1% specially for minute seed. Plant per cent gives useful information for collection of required quantity of seed.- Bamboo Improvement Works in Arunachal Pradesh

Arunacbal Pradesh Is very rich in bamboo having more than 30 species in wilderness. Bamboo is used by the tribal people for a variety of purposes and is very much linked with their socio-economic needs. Keeping in view the importance of bamboo, its improvement work was taken up in Arunachal Pradesh during 1980 with the objective to establish germ-plasm banks of improved materials and to multiply it for supplling to the villagers. Eight important species of bamboos were taken up and plus bamboo were selected from the bamboo grown in the villages and also from natural forests. Offsets were purchased from the villagers and bamboo germ-plasm banks were established during 1984 over 6 hectares at Chessa and Namsai. Among the plus bamboo BB/CH-4, BT/NS-13, BT/CH-7, BP/CH-3, BP/CH-7, BN/CH-I, Nangal CH-2 and CH-4 bave shown superiority over other plus bamboo.- Status and Distribution of Willow Mortality in Lahaul and Spiti Cold Desert of Himachal Pradesh

A survey on the status and distribution of willow mortality in the cold desert of Lahaul and Spiti district of Himachal Pradesh was conducted during 2007. Large scale willow mortality ranging from 2 to 93.8 per cent was recorded in Lahaul sub-division. The extent of mortality was higher in Chandra valley as compared to Pattan and Bhaga valleys. In Spiti sub-division willow mortality was recorded only at Qurith (2%). Investigations revealed that Cytospora canker caused by Cytospora chrysosperma is the major cause of willow mortality. At few places scale insect (Lepidosaphes sp.) infestation was also recorded. Based on the causes of the mortality, a package of recommendations has been suggested to reduce the willow mortality in the cold desert areas.Keywords

Juvenile growth traits were studied in the recently introduced clones of Salix species from twelve countries including Croatia, Sweden, Italy, Hungary, Turkey, Japan, Yugoslavia, UK, Belgium, New Zealand, Germany and USA which were screened in the nursery by applying 'augmented completely randomized design' with three check clones (SI-64-017, SI-63-007, Kashmiri willow). Significant differences were recorded for morphological traits among test clones and test verses check clones except in leaf length among test clones and volume index, leaf length and petiole length among check verses test clones. The clones SI-63-016, J-799, PN-722, NZ-1002, PN-733, PN-731, SN-2, S × 61, 194 and 084/03 were found superior to check clones for the growth traits viz., plant height, basal diameter and volume index. Heritability in broad sense (91.08 %) and genetic gain (75.24 %) was found highest for leaf breadth and volume index, respectively. Maximum positive and significant correlation coefficient (0.959) was recorded for basal diameter with volume index. Principal component analysis through correlation matrix revealed that three out of eight components contributed 85.03 per cent of the overall variation out of which the first principal component (λ=3.086) explained 38.57 per cent of the variance weighted maximum (0.937) by volume index. These promising clones selected under the present study will be further tested under multi-location trials to study the genotype x environment interaction at different sites for analysis of suitability of clones.Keywords

The genetic improvement of willows through traditional breeding can be facilitated by pollen collection and storage. The female flower receptivity need not be synchronized with pollen shed for breeding. Studies on collection, viability and storage of pollen of commercially important Salix spp. was carried out for implementation of successful breeding programme. The pollen size varied from 20.12 μm to 40.49 μm with clone 131/25 exhibiting maximum size whereas S. babylonica registered minimum size. Germination percentage of the pollen extracted with toluene (Solvent method) was comparatively lower then that of untreated pollen., pollen germination percentage varied between 54.28 to 46.45 per cent in 2009 and 62.88 to 46.88 per cent in 2010. Maximum pollen viability has been recorded at the time of pollen collection. Pollen grains retained higher viability at -20°C even after nine months as compared to pollen stored at 4°C in both the years. Pollen stored at two different temperatures revealed that there was a linear decrease in pollen viability with increase in storage period. The main pollinators found affecting cross pollination among willows were honey bees (Apies spp.), flies, wasps (Polister spp.) and bumble bee (Bambus spp.)Keywords

Variability studies in fodder quality parameter in Anogeissus latifolia Wall (Family-Combretaceae) was undertaken in four districts of Himachal Pradesh viz., Solan, Sirmour, Kangra and Una at eight sites under different elevations in three diameter classes viz., 10-20 cm (small) 20-30 cm (medium) and 30-40 cm (Large). Proximate principles of leaf fodder in S4 (Chaoban, Distt Sirmour) and S1 (Jadli, Distt Solan) exhibited maximum variation in almost all nutritional traits. Study concluded indicating that direct selection from the altitude ranging between 600 m to 1000 m amsl in large diameter class (30-40 cm) is recommended for the improvement of species and to have superior genetic gains for further breeding works.Keywords

Correlation studies were performed for progenies of thirty two plus tree on growth and fodder quality characterstics of Bauhinia variegata. A positive and highly significant correlation existed between basal diameter and number of branches (0.798), leaf area and lamina length (0.846). Significant and positive correlation was also observed between basal diameter and plant height (0.547), plant height and number of branches (0.520), highly significant and positive correlation existed between leaf fresh weight and leaf dry weight (0.984), phenotypic correlation coefficients were lower than their corresponding genotypic values. This could be either due to the modifying effect of environment or the strong inherent association of characters at genetic level. High significant and positive phenotypic (0.761) and genotypic (0.833) correlation existed between number of branches and basal diameter. Highly significant and positive genotypic and phenotypic correlations were observed between leaf fresh weight and leaf dry weight (0.989). Leaf fresh weight and leaf dry weight showed significant correlation with most of the morphometric traits. Simple correlation of morphometric traits with mineral nutrients were found non-significant. Genotypic correlation coefficients were found greater than phenotypic for most of the morphometric and leaf fodder traits.Keywords

Twenty-five promising willow (Salix spp.) clones were selected after nursery screening twice, collected from six countries. Genetic relatedness among the clones was estimated using RAPD markers. Out of 20 primers tested, 16 primers were selected based on the amplification of DNA. A total of 339 bands were scored of which 338 were polymorphic showing high (99.7%) rate of polymorphism. The similarity coefficient ranged from 0.71 to 0.87. These clones were grouped into six different clusters. Clone PN-733 (Salix nigra from New Zealand) appeared to be the most diverse (76 %) from rest of the genotypes on the basis of dendrogram. Maximum similarity (87%) was observed between clones SI-63-007 (S. alba from Italy) and V-99 (Salix alba X S. rubens from Croatia). RAPD analysis proved helpful for estimating the magnitude of genetic diversity at molecular level. The clustering further indicated that the geographic distribution may not be the true index of genetic diversity in willow clones. The marker system was found useful for developing unique fingerprints of three genotypes. On the basis of banding pattern RAPD's were effectively used for molecular characterization of willow clones used in this study.Keywords

The present study on Ulmus villosa was carried out in Himachal Pradesh to know the progeny performance and estimate genetic variability for biomass traits of progenies at nursery stage. Seeds were collected from five mother trees each at six seed sources and progenies were raised. All the biomass characters varied significantly among different seed sources and trees within seed source. Root dry weight was found to have higher coefficient of variability, whereas shoot dry weight and shoot fresh weight had higher heritability with moderate genetic gain suggesting their importance for the success of improvement through selection. Genotypic and phenotypic correlations for all possible pairs were also found out and discussed. Highly significant and positive genotypic and phenotypic correlations were observed for fresh shoot weight with fresh ischolar_main weight and fresh shoot weight with dry shoot weight indicating their significance in the indirect selection.Keywords

Molecular diversity among 23 promising progenies of Ulmus villosa, which were raised from the seeds collected from various seed sources in Himachal Pradesh (India), was estimated using 10 RAPD primers. A total of 57 markers were generated, all of the 10 primers showed 100 per cent polymorphism. The similarity coefficient among 23 progenies of U. villosa ranged from 0.00 to 0.70. In which, progeny Jugahan-T<SUB>3</SUB> was found to be the most divergent which separated 3 itself from rest of the progenies at similarity value (0.04) and could be used as a parent in hybridization programme and further improvement programmes. The progenies were grouped into 4 clusters. The cluster II consisted maximum of 12 progenies followed by cluster III (5 progenies), cluster IV (4 progenies) whereas cluster I consisted of single progeny. RAPD analysis proved helpful for estimating the magnitude of genetic diversity at molecular level.Keywords

Twenty-three tree willow clones comprising of seven species were studied for variability of photosynthetic traits and their relationship at one year age. Photosynthesis, transpiration and instantaneous water use efficiency (WUEi) were determined and the data were further subjected for the estimation of genotypic and phenotypic coefficient of variability (GCV and PCV), heritability and genetic gain (as per cent of mean). Variability estimates were calculated for growth parameters viz., height, collar diameter, volume index, number of branches, number of nodes, internodal length, leaf display and leaf area. Among all the parameters volume index showed widest range of values (9.29-721.50, mean 356.42). The narrowest range was recorded for leaf display (195.0-291.0, mean 238.17). The maximum GCV (39.99) was recorded for transpiration, followed by photosynthesis (38.36) and least in case of WUEi (19.71). Heritability (h2 b.s.) was recorded maximum (85.30) for transpiration, (80.00) for photosynthesis and (26.55) for WUEi. A positive significant correlation (r= 0.754) was observed between photosynthesis and transpiration. WUEi showed significant negative correlation (r = -0.364) with transpiration whereas positive non significant (r = 0.209) with photosynthesis. Selection of both traits i.e. photosynthesis rate and WUE are important in order to make photosynthesis more effective using water efficiently to produce higher yield.Keywords

The species and hybrids of willows were procured during 2002-04 from twenty countries and subjected to nursery screening. To test the field performance the selected 15 promising clones were planted in farmers fields in March, 2007. The five years growth performance depicted that clone J-194 had highest plant height (16.66 m), diameter at breast 3 height (19.97 cm) and volume index (0.679m3) along with most straight bole (4.60). The clones Kashmiri willow (16.08 m) and PN-722 (16.00 m) were at par with J-194 for height growth followed by the clones NZ1002 (15.18 m), J-799(14.63 m), J-795 (13.38 m) and PN-733 (13.34 m). The clones PN-722 (18.82 cm) and J-799 (17.80 cm) showed diameter growth (DBH) at par with clone J-194. Straightness of J-799 (4.50), J-795(4.38), SI-63-007(4.21), SI-64-017(4.09), PN 722 (4.04) and V-99(3.75) clones was at par with J-194. Heritability estimates (broad sense) of the traits ranged from 64.80 per cent in volume index to 94.67 per cent in bole straightness. On the basis of initial screening in field conditions clones namely J-194, J-799, J-795, PN 722 and NZ 1002 were found suitable for large scale plantation in this area.Keywords

Twenty four populations of Sapindus mukorossi Gaertn. scattered over a wide range upto 1500 m elevation in Himachal Pradesh were evaluated to observe variation in seed oil contents and seed oil quality traits. Significant variation among different populations were observed for per cent seed oil content and non significant for oil quality traits. Maximum oil content was recorded in Garsa (18.92%) population. D.B.H classes did not show distinct variation for seed oil content and oil quality traits. Study concluded that on an average, the populations of Garsa (Kullu Forest Division) of Himachal Pradesh was found to be best over all other populations for both the traits. This investigation will be useful for further improvement of the species for improved genetic gain.Keywords
