| 摘 要： | 应用通径分析对15个甘蓝品种的叶球重和与其构成性状--植株开展度、叶球横径、球叶数等--的分析表明,上述3个构成性状对叶球重的通径系数分别为P1y=-0.0493、P2y=0.5159、P3y=1.201;3性状和叶球重的遗传相关系数分别为r1y=0.4167、r2y=-0.1807、r3y=0.8904.球叶数和叶球横径是决定叶球重的主要因素,2性状须综合考虑;植株开展度对叶球重的有利作用通过间接效应而表现。

| Abstract: | Three traits namely plant width,head transverse diameter and head leaf numbers of 15 cabbage cultivars were studied with head weight by path analysis.The results showed that path coefficients between head weight and the three traits are P1y(-0.0493),P2y(0.5159),P3y (1.201)respectively.The genetic correlation coefficients are r1y(0.4167),r2y(-0.1807),r3y=(0.8947)respectively.Transverse diameter of head and numbers of head leaves are closely associated with head weight.Width of plant af fects head weight indirectly by transverse diameter and numbers of head leaves. |
