Performance of pearl millet isonuclear hybrids involving different cytoplasmic male-sterility systems



Performance of pearl millet isonuclear hybrids involving different cytoplasmic male-sterility systems



Plant Breeding 115(2): 140-142



The performance of pearl millet hybrids involving four sources of cytoplasmic male sterility (CMS), including the most-exploited A-1 source, was compared to evaluate the effects of cytoplasm on grain yield. The mean grain yield of hybrids possessing A-2, A-3 and A-4 cytoptasms was either similar to or significantly higher than that of their counterpart hybrids with A-1 cytoplasm. Hybrids based on A-3 and A-4 cytoplasms produced, on average, 8% more grain compared with those based on A-1 cytoplasm. This suggested that these CMS sources could be used as alternatives to A-1 cytoplasm to widen the cytoplasmic base of hybrids. The results indicated that most of the variation in hybrids was accounted for by pollinator and cytoplasm x pollinator interactions, suggesting the use of genetically diverse pollinators in pearl millet hybrid breeding.
