摘　　要：将诸葛菜作为油料作物进行引种栽培，并对诸葛菜栽培条件下各农艺性状间的相关关系和单株产量构成因素进行了回归和通径分析。结果表明，在诸葛菜单株产量的直接构成因素中，贡献最大的是全株角果数，其次是每角粒数，再次是千粒重。一次有效分校数对单株产量的直接作用较小，但通过全株角果数的间接作用超过了每角粒数和千粒重的直接作用。其余性状与单株产量无显著偏相关，对单株产量的偏回归系数和通径系数也不显著。Orychophragmus violaceus was cultivated for the first time in China as an oil crop. Correlations, regression and path analyses of the components of the seed yield per se in this species were carried out. According to our results the trait that contributes the most to seed yield per se was the number of pods per se, then the number of seeds per pod, then the weight per 1000 seeds. Direct effect of the number of prirnary branches was rather srnall,but its indirect effect on the seed yield per se via the number of pods per se was rather large.Other traits had no significant partial correlations with seed yield per se, and their regression coefficients and path coefficients to the seed yield per se were not significant either.
