英文摘要Heterosis has been exploited in many crops and made a significant contribution to the world food supply. Genetic distance (GD) is one of valuable criteria for selecting parents in hybrid breeding. The objectives of this study were to estimate GD between a novel photoperiod-thermo sensitive male sterile wheat line 337S and several common cultivars using simple sequence repeat (SSR) markers, and to evaluate the relationship of GD and heterosis. The line 337S, as a maternal parent, was crossed with 16 common wheat varieties to produce 16 hybrids. Eight agronomic traits were investigated for the parents and F1 hybrids. Mid-parent heterosis (MPH) and specific combining ability (SCA) were calculated. GD and cluster analysis were performed among the 17 parents. The correlations of GD with F1 performance, MPH and SCA were analyzed. The results showed that GD estimates among the 17 parents averaged 0.42 with a range from 0.26 to 0.57, and the averaged GD between 337S and the 16 parental cultivars was 0.44. Cluster analysis separated the 17 parents into three main groups. SSR markers were useful in analyzing genetic divergences among the 17 parental lines. However, GD based on SSR markers poorly correlated with F1 performance, MPH and SCA. Thus, GD revealed by SSR markers can not provide a reliable prediction in practical wheat hybrid breeding.
