Abstract

In Uttar Pradesh (UP) there is only one representative of indigenous genus Populus, i.e. Populus ciliata. However, a number of exotic species and their clones were tried in UP since almost 50 years ago and after a decade of rigorous trials both in hills and plains (mainly Tarai region) only P. yunnanensis and P. deltoides were found most promising species respectively. In UP breeding of Poplar was also started successfully from 1982. By breeding, a number of new clones of Poplar have been developed and more than 30 clones have been found promising which have 25% to 70% more productivity than the exotic clones. The work on breeding and selection of new clones continues.

Abstract

The seed samples of D. sissoo were collected from 58 CPTs representing 7 seed sources of U.P. These samples were studied to evaluate different parameters viz. length, breadth, thickness, shape index (l/b ratio), seed weight, viability and germination percentage. Significant variation was observed between seed sources and studied parameters. On the basis of over all performance, the seed sources can be grouped in descending order as Mathura > Etawah > Kanpur > Ramnaghar > Lucknow > Haldwani > Mau. The performance of some CPTswas found poor with low values of viability and germination. Hence, these ePTs must be avoided for future collections. However, seeds from better CPTs could he used for further genetic improvement programmes.

Abstract

The occurrence of multiple seedlings were observed in Neem (Azadirachta indica) during the germination studies in different Seed Sources of seeds. In the case of Neem the emergence of multiple seedlings is not due to polyembryony but due to sowing of seeds along with the endocarp of fruit not kernel. Each endocarp encloses 1-4 seeds in it. However, in the present study it differs in different Seed Sources.

Abstract

The study of genetic diversity of Dendrocalamus strict us Nees for increasing the productivity of Bamboo plantation in Vindhyan Region of Uttar Pradesh was confined to diameter and volume of culm, which are the major traits for better quality of Bamboo. The rhizomes of one year old culms were collected from the different CPCs as selected in Renukoot, Mirzapur and Obra Forest Divisions. The collected rhizomes were raised at Research Nursery, Kotwa, Mirzapur for ex-situ conservation. Significant variations were observed in diameter of the culm and volume along with culm height among all the 12 CPCs. It provides a clear cut indication for good selection of CPCs for cultivation at Mirzapur and adjoining places for improvement and multiplication of good quality bamboo vis-a-vis enhancing the yield.
