对10个甘蓝品种和杂交组合的叶球产量性状的相关和遗传通径分析表明:纵径对叶球产量的影响最大,横径对产量的影响次之。外叶数对叶球产量的直接作用不大,它主要通过纵径和横径间接地影响叶球产量。
The correlation and genetic path analysis of the leaf traits of 10 cabbage cultivars and cross combinations indicated that the vertical diameter had the greatest effect on the yield of leaves and the secondary diameter had the second largest impact on the yield. The outer leaf number has no direct effect on leaf ball production, it mainly affects the leaf ball production through the longitudinal and transverse diameters indirectly.
