SUMMARY
An investigation was conducted in Sorghum bicolor with line x tester (3 females x 6 males) to study the combining ability effects for fodder yield and other yield related traits. Analysis of variance revealed the presence of sufficient variation in the study material. The SCA variance was greater in magnitude than the GCA variance for most of the traits under study indicating predominance
of non-additive gene action in the genetic control of those traits. Line 14A found good general combiner for GFY in 1st and 2nd cut, regeneration potential, DFY in 1st cut, GFY in 2nd cut, plant height whereas tester HJ 541 emerged as a good combiner for GFY in 1st cut, DFY in 2nd cut, no. of leaves per plant, leaf breadth. For GFY in 1st cut significant high SCA effects exhibiting crosses were 31A × SSG 59-3, 9A × SGL 87, 31A × S 437 and 9A × HJ 541.
