Abstract:

In order to evaluate the germplasm resources of 30 species of Clausena anisum-olens (Blanco) Merr., nine fruit traits including weight of single fruit, fruit equatorial diameter, fruit transverse diameter, fruit shape index, weight of single seed, seed equatorial diameter, seed transverse diameter, edible rate, soluble solid content were measured and analyzed by statistical analysis. The variation of weight of single fruit of C. anisum-olens (Blanco) Merr. was the most significant, while the variation of fruit shape index was the most non-significant. The soluble solid content was not correlated with the other eight indices significantly, and there was significant and extremely significant correlation between the other indexes. Thirty species of C. anisum-olens (Blanco) Merr. germplasm resources were clustered into three categories by factor analysis and cluster analysis. There was a certain correlation between fruit trait and geographical origin. Fruit traits of 13 germplasm from Longzhou County and Ningming County were the best.

Key words: Clausena anisum-olens (Blanco) Merr., germplasm resources, fruit trait, factor analysis, cluster analysis
