Abstract

Correlation studies in five line, twelve testers and the resultant sixty hybrids developed by line x tester design revealed that grain yield per plant was positively and significantly correlated with all the growth parameters related with drought viz., chlorophyll content at 75 DAS, proline content, specific leaf weight, leaf area ratio at 75 DAS, crop growth rate at 60-75DAS, relative growth rate at 60-75 DAS and net assimilation rate at 60- 75DAS. This indicated that increase in grain yield in Rabi sorghum under drought condition may be because of increase in one or more of these growth parameters.

Abstract

For callus induction studies explants i.e., shoot tips hypocotyls and ischolar_mains were excised from six days aseptically grown seedlings. NAA 2 mg/l+BAP 2 mg/l was found best among various combinations used for induction of callus. For differentiation of callus BAP 1 mg/l+NAA 0.5 mg/l treatment combination was found to be the best that resulted in maximum number of shoot lets, for differentiation followed by profuse ischolar_maining to the regenerated shoots. For the completely developed plantlets, the maximum survival was observed with the hardening treatment where in the plants were directly transferred into polybags were kept in mist chamber.

Abstract

The present investigation entitled “Studies on new male sterile lines and restorers in rabi sorghum” was undertaken to assess the per se performance of parents, to estimate the amount of heterosis for yield and yield components, to estimate the combining ability and fertility restoration and to identify heterotic combinations for further study. Significant heterosis has been recorded for yield and yield components in most of the crosses. The hybrid ms-104A×AKR-354 recorded highest heterosis and heterobeltiosis for grain yield and also exhibited significant heterosis except leaf area. For grain yield, the hybrid 104A×AKR-354 was followed by ms-104A×AKR-388-1, ms-104A×AKR-368 and AKRMS-69×AKR-388-1.

Abstract

A field experiment was conducted at Cotton Research Unit, Dr. PDKV, Akola during 2004-05 under rainfed condition in randomized block design with four replications. Three Bt Cotton hybrids viz, MECH-12 Bt, MECH-162 Bt and MECH-184 Bt and two check hybrids viz, PKV-Hy-2 and NHH-44 were grown at 90 x 60 cm as IPM component. The plant protection packages recommended under IPM module which was developed by Dr. PDKV, Akola during 2003-04 were adopted on all the cotton hybrids. From the present study it was observed that are the three Bt cotton hybrids were found promising in recording significantly less open boll and loculi damage at harvest as compared to check hybrids in spite of no sprays for bollworm control on Bt cotton hybrids whereas three sprays for bollworm control on check hybrids.

Abstract

In micropropagation of Momordica dioica Roxb., the axillary bud was found as a best explant than shoot tip for rapid multiplication of three local genotypes comprising of two female (AKSG-5 and AKSG-35) and one male genotype (AKSGM-1). Basal MS medium containing AdSO₄ (70 mg/l or 80 mg/l) supplemented with BAP (1.0 mg/l) and NAA (1.0 mg/l) produced maximum multiple shoots (more than 5 per culture) with better growth response.

Abstract

Healthy shoots, which have there own ischolar_main system, are able to survive and become complete plantlets. The healthy well developed multiple shoots were individually separated and kept for ischolar_maining on various media composition. 80 per cent ischolar_maining was obtained in AKSG-5 on RM₆ (MS+AdSO₄ 80 mg/l + IBA 1.0 mg/l). The highest ischolar_maining percent in AKSGM-1 (93%) was obtained on RM3 (MS+IBA 1.0 mg/l) followed by AKSG-35 (86.67%) was observed. Similar results reported by Deokar et al. (2003) and they obtained 80% ischolar_mains in spine gourd on MSHP + ADS 80 mg/l + IBA 1.0 mg/l + 0.9% agar agar and Geeta Kulkarni obtained (86.66%) ischolar_maining response to Kartoli on MS+3ppm NAA + 0.8% Agar + 3% sucrose with activated charcoal. In present investigation, in AKSG-5 (4.33) primary ischolar_mains per culture with 4.17 cm ischolar_main length and in AKSG-35 (4.67) primary ischolar_mains per culture with 4.67 cm ischolar_main length in AKSGM-1 (4.67) primary ischolar_mains with 4.67 cm ischolar_main length were recorded on RM₆ (MS+AdSO₄ 80 mg/l + IBA 1.0 mg/l) were recorded.
