Combining ability for fodder yield and its components in Sorghum (Sorghum bicolor L)

Abstract

Seven lines were crossed with five testers in a L x T mating design to estimate the combining ability for fodder yield insorghum. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., daysto 50 % flowering, plant height, number of tillers, number of leaves, leaf length, leaf breadth, stem diameter, green fodderyield and dry fodder yield. The parent’s viz., ICSA 693 and PKB 192 can be considered as superior parents in the presentstudy as they recorded high per se performance with positively significant general combining ability effect for green fodderyield/plant. Among the 35 hybrids evaluated, crosses viz., ICSA 547 x PKB 192, ICSA 374 x PKB 161, ICSA 403x CSV 15-217 were considered as superior hybrids as they recorded high per se performance and significant sca effect forgreen fodder yield/plant.
