| Abstract: | The genetic distances among 18 cytoplasmic male sterile lines and 11 restorer lines were analyzed with molecular markers derived from yield-related functional genes.The correlation between parental genetic distance and heterosis was investigated by analyzing the performance of 47 combinations.The results showed that the genetic distance was significantly correlated with yield heterosis(r=0.29*),but not significantly correlated with heterosis for other traits,such as number of effective panicles per plant,se... |
