| dc.description.abstract | Investigations were conducted for critical assessment of adaptability, associations and path effects in berseem. Twenty genotypes including two check varieties (Wardan and Mescavi) were evaluated at Rahuri, Maharashtra in three predictable environments (E^, E2» E3) during Rabi.1994- 95 and three cuts were taken in each environment. Plant height, number of tillers per plant and per meter length, L/S ratio, green and dry fodder yield per plant, crude protein content and green fodder yield per meter distance were studied. Significant G x E interactions were observed for all the characters studied in all the environments. Importance of linear component of G x E interaction was observed in the expression of plant height (in E^, E2 and over all environments), number of tillers per plant (in E^), number of tillers per meter length (in E2» E3 and over all environments), green fodder yield (in E^, E2 and over all environments), dry fodder yield per plant (in all environments) and green fodder yield per meter distance (in Ej, E3 and over all environments). Pooled deviation (nonlinear) effects were highly significant for all the characters except number of tillers per plant in E ^ environment. The genotypes viz., JHB-93-3 (plant height), JHB- 92-2 (number of tillers/plant, crude protein content), JHB- 93-4, HFB-135, Wardan and Mescavi (number of tillers/plant) had wider adability in nine environments (i.e. over all environments). Further, the genotypes viz., JHB-92-2, HFB- 135, Mescavi in all the three predictable environments (E^, E£ and E^)^txe stable for most of the characters including green and dry fodder yield per plant. The genotypes, BL-126 for number of tillers per plant, Mescavi for L/S ratio, BL-122 and JHB-93-2 for green fodder yield per plant in E2 environment, While, the genotype BL-126 for number of tillers per meter distance, JHB-93-4 for green and dry fodder yield per plant and protein content and Wardan for dry fodder yield and crude protein content in E3 environment appeared adapted to rich environment (i.e. with below average stability). Whereas, the genotypes,BL-130 for green forage yield and BL-102 for L/S ratio in E2 and E3 environments, respectively were adaptated to poor environment having above average stability. The correlation studies indicated the importance of all the characters except L/S ratio as they were significantly associated with green fodder yield per meter distance in all the three predictable environments. However, considering direct and indirect effects under various environments, the components such as plant height, crude protein content, number of tillers per plant and green fodder yield per plant appeared most important in the selection criteria aiming at improvement \r\ fodder yield of berseem. | en_US |
