DIVERSITY ANALYSIS OF MAIN AGRONOMIC CHARACTERS OF DIFFERENT SWIDA WILSONIANA CLONES
JNG-ZHEN CHEN
Abstract
To produce high-yield and high-oil species, 28 agronomic traits in 7 Swida wilsoniana clones were measured and analyzed using variance, principle components, cluster, and correlation analyses. Variance analysis showed that the coefficients of variation of the 28 agronomic traits ranged from 8.04% to 94.30%, and the largest variation was in aspects of leaf pattern, such as leaf shape, color, and leaf margin character. Phenotypic differentiation coefficients ranged from 45.27% to 96.40%, which showed 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.
