本文对我国北方不同生态型白菜的３５个品种的７个主要农艺性状进行了相关及通径分析，结果表明：生育期、株高、球形指数和株幅为不易受环境因素影响的性状，其遗传力分别为９８．９％、８０％、７６．２％和５０％；产量、叶片数、帮叶比为较易受环境因素影响的性状。株幅、球形指数对产量的直接影响较大，其直接通径系数为０．８６４和０．７１１。 In this paper, seven major agronomic traits of 35 varieties of cabbage in different ecotypes in northern China were studied. The results showed that: growth stage, plant height, sphericity index and plant width were not easily affected by environmental factors, Heritability was 98.9%, 80%, 76.2% and 50%, respectively. Yield, number of leaves and leaf ratio were more susceptible to environmental factors. The direct effect of plant width and spherical index on yield was significant, and the direct path coefficient was 0.864 and 0.711.
