Combining ability effects were estimated for grain yield and smut severity in a line X tester crossing programme comprising 70 hybrids produced by crossing 10 lines (5 male sterile and 5 maintainer lines) with 7 restorers of diverse origin. The material was raised in two environments (dates of sowing) at Hissar. Parents and hybrids differed significantly for gca and sca effects, respectively. 10A and 10B among lines and H 833-2 among testers showed consistently high gca effects for grain yield and smut severity. Both additive and non-additive gene effects seemed to be important in the control of the two characters. No cytoplasmic effect was observed in the development of smut disease. Among hybrids, the best performance was given by cross 10 AX77/181-4-4-3-1-5. The results indicated that the performance of hybrids for smut severity can be predicted with greater reliability based on gc alone than for grain yield.
