Abstract:

The effect of cytoplasm on hybrid mean performance for seed yield and its contributing traits was investigated by evaluating 50 hybrids (25 A×R and their corresponding 25 B×R hybrids) and 10 parents (five CMS A lines and corresponding maintainer lines) along with standard check hybrid DRSH-1. These isonuclear alloplasmic hybrids were observed for quantitative traits viz., days to 50 per cent flowering, head diameter, stem diameter, plant height, 100 seed weight, volume weight, days to maturity, hull content, seed yield plant-1and oil content. Significant variation was observed within the A×R and B×R group of hybrids for all the traits. But, differences between A×R and B×R group of hybrids were not significant for any trait except for hull content and oil content indicating poor influence of male sterility inducing cytoplasm. However, significant differences observed in few A×R and B×R hybrids for mean performance might be attributed to cytoplasm × nuclear interactions. The differences varied in their direction and magnitude without showing a definite pattern in favour of a particular cytoplasm. However, the differences so detected varied with the trait and nuclear genetic background.
