COMBINING ABILITY OF CERTAIN POPULATIONS AND LANDRACES OF PEARL MILLET, PENNISETUM AMERICANUM (L.)

Abstract

                                A diallel cross study involving 12 parental populations of pearl millet originating from India and Africa, indicated predominantly additive gene action for various traits studied. The significant specific combining ability variances for head number and grain yield, indicated the importance of non-additive genes for these characters. The matemal effect was high for the head length. Examination of parents with high gea and high sca crosses revealed that most productive combination of crosses involved the unrelated parents from the diverse origin.
