Abstract:

In order to breed Ardisia crenata so well, the test compared the agronomic traits of Ardisia crenata from eleven provenances, the results showed: (1) There were highly significant differences of agronomic traits of Ardisia crenata among different provenances (P＜0.01), the coefficient of variation among those traits was 9.52%-50.26% and had great choose potential. The coefficient of variation of the fruit number per ear, ear number, blade pitch, 100-fruit weight, branch number, canopy height ratio, length of fruit stalk, stem diameter and ear length were high. The coefficient of variation of the canopy diameter, trunk height, plant height, leaf width, leaf length-width ratio, fruit longitudinal diameter, petiole length, fruit width and leaf length were small. (2) Plant height and trunk height, blade pitch and petiole length, fruit longitudinal diameter and fruit width had positive correlation relationship. (3)Adopt the sort result of principal component analysis, select Nanning Guangxi, Ji'an Jiangxi provenances by plant form traits, select Zhangping Fujian provenance by leaf form traits, select Zhangping Fujian, Dujiangyan Sichuan, Songyang Zhejiang provenances by ornamental value of fruit, select Wuping Fujian, Kaihua Zhejiang, Huichang Jiangxi provenances by comprehensive assessment of all traits.
