| dc.description.abstract | Investigations were conducted for critical assessment of adaptability, associations and path effects in forage sorghum. Ten genotypes were evaluated at Rahuri in kharif, rabi and summer with their ratoons, during 1993-94. Green and dry forage yield, days to 50 per cent flowering, plant height, number of leaves, stem girth, leaf area and L/S ratio and two quality traits viz.,T.S.S. and crude protein content were studied. Significant G x E interaction was observed for all the characters studied for both, main and ratoon crops. Importance of linear component of G x E interaction was observed in the expression of dry matter yield of main crop and green forage yield and T.S.S. in ratoon crop. Pooled deviation (non-linear) effects were highly significant for all the ten characters studied. The kharif season was graded as the most favourable environment for most of characters which was followed by summer and rabi. The genotypes viz., RFSS 56 (plant height and T.S.S.), RFSS 23 (number of leaves), RFS 89-11-1 (number of leaves, stem girth, crude protein content), RFSH 89-1 (early flowering, T.S.S. and crude protein content), RFSH 88-1 (early flowering, number of leaves, stem girth, T.S.S.), RFSH 92-2 (dry matter yield), R.S. 11-4 (early flowering, stem girth, crude protein content), in main crop, while the genotypes/ RFSS 23 (L/S ratio, dry matter yield), RFSS 56 (early flowering, green forage yield, T.S.S.), RFS 88-11-4 (number of leaves, stem girth, L/S ratio,crude protein content), RFSH 89-1 and R.S. 11-4 (plant height, number of leaves, stem girth), RFSH 92-1 (plant height, T.S.S.), RFSH 92-2 (crude protein content), SSG 59-3 (early flowering), in ratoon crop had wider adaptability. The genotypesRFSS 23/_for early flowering and green forage yield in ratoon crop appeared adapted to rich environment, while^genotype RFSS 56 for dry matter yield in main crop and RFSH 88-1 for T.S.S. in ratoon crop were adapted to poor environment. Number of leaves, stem girth with green forage yield and leaf area with both green and dry matter yield had significant positive correlation. The dltf£ct effects of the leaf area, L/S ratio and crude protein content on their correlation with dry matter yield were also positive. Leaf area, crude protein content and green forage yield appeared as the important characters contributing to dry forage yield. | en_US |
