Diversity analysis of main agronomic characters of different Swida wilsoniana clones

摘要

In order to produce high-yield and oil content Swida wilsoniana species, 28 agronomic traits in 7 Swida wilsoniana clones were measured and analyzed from variance, principle components, cluster, and correlation. Variance analysis results showed that the variation coefficients of the 28 agronomic traits ranged from 8.04% to 94.30%, and the largest variation was from leaf pattern, such as leaf shape, color, and leaf margin character. And the phenotypic differentiation coefficients ranged from 45.27% to 96.40%, which indicated that the characters were relatively genetically stable. Main inheritance was represented by 4 principal components, which were inflorescence, fruit, oil content, and fruit quantity per cluster. Principal components analysis clustered the 7 clones into 4 groups. High-yield and high-oil target species can be produced by hybridizing groups 2 and 3.
