摘要：

为更好地进行朱砂根选育，试验比较11个种源朱砂根的农艺性状。结果表明：（1）朱砂根的农艺性状在不同种源间存在极显著差异（P＜0.01），各性状变异系数在9.52%~50.26%，选择潜力大。其中每穗果数、果穗数、叶距、果百粒重、分枝数、冠高比、果柄长、茎粗、果穗长的变异系数大，冠径、干高、株高、叶宽、叶长宽比、果纵径、叶柄长、果横径、叶长的变异系数小；（2）株高与干高、叶距与叶柄长、果纵径与果横径之间存在正相关关系；（3）采用主成分分析综合评价的排序结果，株形性状上选择广西南宁、江西吉安种源，叶部形态上选择福建漳平种源，果实观赏性上选择福建漳平、四川都江堰、浙江松阳种源，所有性状综合评价选择福建武平、浙江开化、江西会昌种源。

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.
