摘　　要：甘、白杂交是创建聚生角果油菜的主要途径。聚生角果油菜每果柄的果皮面积和籽粒产量较单生角果高１倍左右。甘蓝型聚生角果油菜的染色体数与甘蓝型油菜没有差异，聚生角果性状受３对以上核隐性基因控制。聚生角果果皮对籽粒的贡献较单生角果高７％～２０％。聚生角果油菜对氮、磷的吸收、利用与甘蓝型油菜差异显著。Hybridization of B.napus .L.and B.campestris. L.was a main method of creating aggregate silique rapeseed.The area of pericarp and seeds weight per fruit handle was 50% more than those of solitary silique.Chromosome number of aggregate silique rapeseed was the same as solitary silique rapeseed.The character of aggregate silique was controlled by three pairs of recessive nuclear genes.The contribution of the photosynthesis product of pericarp to seeds in aggregate silique was 7%～20% higher than that in solitary silique.There were differences between aggregate silique rapeseed and solitary silique rapeseed in absorbing and utilizing nitrogen and phosphorus
