Abstract

The performance of pearl millet hybrids involving four sources of cytoplasmic male sterility (CMS), including the most-exploited A1 source, was compared to evaluate the effects of cytoplasm on grain yield. The mean grain yield of hybrids possessing A2, A3 and A4 cytoplasms was either similar to or significantly higher than that of their counterpart hybrids with A1 cytoplasm. Hybrids based on A3 and A4 cytoplasms produced, on average, 8% more grain compared with those based on A1 cytoplasm. This suggested that these CMS sources could be used as alternatives to A1 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 × pollinator interactions, suggesting the use of genetically diverse pollinators in pearl millet hybrid breeding.
