Abstract:

Combining ability analysis was done for thirteen parents including three cytoplasmic male sterile (CMS) lines and ten testers along with their thirty crosses. IR 58025A (CMS line) was conferred as the great general combiner distinguished for “grain yield per plant” because of its positive GCA impact. Among the ten testers, B.D. Safri, ARC 10550, R1892-486-1-151-1, IC 540584 and CR-3848-2-1-1-2 were distinguished as great combiner for the same trait and other related characteristics. “B.D. Safri” was recognized as great general combiner for the greater part of the yield related attributes. IR 58025A/ CR-3848-2-1-1-2 showed the highest SCA value followed by IR 68888A/ IC 540584 and IR 68888A/ R1892-486-1-151-1 for “grain yield per plant”. IR 58025A/ CR-3848-2-1-1-2, IR 68888A/ IC 540584, IR 68888A/ R1892-486-1-151-1 and IR 79156A/ R1892-486-1-151-1 were recognized as promising crosses for pollen fertility per cent and spikelet fertility per cent on the basis of SCA effect.
