Abstract
An investigation was undertaken to assess the magnitude and direction of combining ability of six cytoplasmic male sterile lines and twelve fertility restorer lines in sunflower. The study revealed that the parental lines RHA-99RTNBr. RHA-284. RHA-299 and CMS-302 possessed genes for earliness. The hybrid CMS-852 x RHA-99RTNBr was found to be the best combination for days to 50 per cent flowering. The lines CMS-207 and CMS-852 and the testers RHA-6D-5-3-6 and RHA-214Br appear to transmit genes for higher seed yield and hence they are suggested for utilization in hybridization programme to obtain better yields. The hybrids CMS-302 x RHA-273 and CMS-234 x RHA-284 were found to be the best combinations for seed yield and oil content, respectively. All the characters were found to be under control of both additive and non-additive gene action with the predomiance of the latter.
