Abstract

19 phenotypic characters of fruit were investigated for 44 Xanthoceras sorbifolia Bunge. The phenotypic variation was studied by using variance analysis, correlation analysis and variation coefficient. The results of variance analysis and variation coefficient analysis showed that the phenotypic characters of fruit were significantly different among individuals of X. sorbifolia, and had great variation in test area. Among 19 phenotypic characters, the variations in fruit number and seed yield were the biggest among different X. sorbifolia individuals and all theirs variation coefficients were over 76%, followed by fruit weight, seed weight and kernel weight with the variation coefficient about 30%, the seed number per fruit and stalk length with variation coefficient over 20%, whereas the characters of seed length, seed width, seed shape index and number of ventricle had smaller variation and their variation coefficients were less than 10%, the least variation was the oil yield of seed kernel and its variation coefficient was only 6.13%, which showed there was evident differences in fruit-bearing capacity for individuals of X. sorbifolia, and had determinate hereditary stability. The correlation analysis results indicated that the correlation of various phenotypic characters of fruit had significant differences. Among them, the correlations of characters for fruit length, fruit width, fruit weight, seed weight, kernel weight, seed length, seed ratio, 1 000-seed weight and stalk diameter of fruit were strong, and significantly related to many phenotypic characters, whereas the characters of fruit shape index, kernel ratio of seed, fruit number and seed yield were only significantly related to a few phenotypic characters, but the correlation of characters for number of ventricle and stalk length was weak and hardly related to any phenotypic characters of fruit. The genetic diversity of fruit phenotypic characters and their significant differences among X. sorbifolia individuals would play an important role in its elite tree selection and breeding.
