Abstract:

In order to breed highyield and highoil species, associated with 28 agronomic traits, 7 Cornus wilsoniana clones were observed and analyzed by variance, principal component, cluster and correlation analysis methods. Variance analysis showed that the variation coefficients of 28 agronomic characters ranged from 804% to 9430%, and the biggest variation was leaf pattern, such as leaf shape, leaf color and leaf margin character. Phenotypic differentiation coefficients ranged from 4527% to 9640%, and it showed that the inheritances of various characters were relatively stable. Main of inheritances were presented by four principal components, which are inflorescence, fruit, oil content and fruit quantity per cluster. According to the factor scores resulted from principal component analysis, these 7 clones were clustered into 4 groups. The highyield and highoil target species can be hybridized by group Ⅱ and group Ⅲ.
