摘要：Predicting progeny performance from parental divergence would potentially enhance the efficiency of breeding. Thirteen clones of Masson pine (Pinus massoniana) were crossed in a 4 x 9 tester mating design and 36 full-sib families were generated. There were significant variations in major growth traits and heterosis of growth traits among the 36 full-sib families. A total of 115 alleles were detected with 30 sets of SSR primers. Genetic distances (GDs) among the crossed clonal pairs were calculated based on SSR data. Parental GDs was significantly correlated with all traits evaluated in the full-sib progeny test (P < 0.05), and the correlation coefficient was 0.398, 0.463 and 0.473 for tree height, DBH and wood volume. Parental geographical divergence was also significantly correlated with growth traits of progeny, while the correlation coefficient was lower than that of GDs. These results demonstrated the potential and feasibility of SSR markers for predicting progeny performance of Masson pine. Considering the influence of genotype x environment interaction effect on the stability of full-sib family performance, our results regarding the moderate contribution of parent GDs in predicting the performance of their full-sib progenies is of importance mainly for the specific region where the progeny test was carried out.
