Abstract

Present investigation involving thirty two hybrids was aimed at study of combining ability for leaf water deficit, grain yield and other related traits of rabi sorghum. Predominance of non-additive gene action was observed for all the traits studied. The parents like 1202 A (primordial differentiation stage). 282 and 168 (Panicle emergence stage). Swarna and M 35-1 (grain development stage), recorded desirable G C A effects for leaf water deficit. The parent 285 revealed desirable G C A effect for grain size. In respect of grain yield and yield cotributing charactors, PD-3-1-11 was most nromising. Crossing of promising lines, selecting desired recombinants and crossing them inter se will be useful in rabi sorghum breeding programme.
