Abstract:
Nature and magnitude of heterosis was studied for ten quantitative characters viz., days to 50% flowering, plant height, leaf breadth, leaf length, stem girth, leaves per plant, leaf area, leaf stem ratio, total soluble solids and green fodder yield in a diallel mating design in forage sorghum. Out of forty five cross combinations, only five hybrids revealed superiority over better parent more than 36% for green fodder yield. Five F1’s hybrids viz., HC-308 x PC-1, HC-308 x HJ-513, HC-260 x PC-1, HC-260 x HJ-513 and HC-260 x HJ 541 more than 36% heterobeltiosis over better parents. These individual crosses can be exploited in heterosis breeding programme for improvement in fodder yield and also suggesting that these attributes were governed by additive genes.
