Combining Ability Studies for Grain Yield and its Components in Pearl Millet (P. typhoides)

V. Rudra Naik, R.L. Ravikumar, T. Madhav Rao

Abstract


Forty hybrids of Pearl millet were produced by crossing five male sterile lines with eight desired inbred lines. The parents and hvbrids were evaluated during kharif 1994 for combining ability. The analysis of variance revealed significant difference between par­ents for ear length, plant height, days to 50% flowering and maturity. The estimates of combining ability variances suggested the Predominance of non-additive gene action in the control of all the yield contributing characters studied. The estimates of gca effects revealed that the female 81A was the best combiner for grain yield and several other yield components. Among males, the genotype IP-12993 had the highest gca effects for fodder and grain yield. It also had significant negative gca effect for days to 50 percent flowering. The hybrid 842A x PMBDN-48 recorded the maximum heterosis for grain and fodder vield.
