Combining Ability for Leaf Water Deficit and Grain Yield in Rabi Sorghum

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.
