选用 5个芸芥与 6个芸薹属种进行杂交 ,研究了芸芥与芸薹属属间杂交的亲和性 ,试验结果表明 :芸芥与芸薹属的远缘杂交属于高度不亲和 ,结角率为 2 .76 % ,结籽率为 1.35 %。影响其杂交亲和性的因素有杂交亲本基因型、杂交组合方式 ,其中以芸薹属作母本的杂交亲和性要高于以芸芥作母本的组合的杂交亲和性。
Five elm mustards and six Brassica species were crossed to study the affinity of the hybrid between Yunjie and Brassica. The results showed that the distant hybridization between Yunjie mustard and Brassica belonged to highly incompatible , Knot angle of 2.76%, seed setting rate of 1.35%. The factors influencing the hybridization affinity are hybrid parental genotypes and hybrid combinations, in which the hybridization affinity of the Brassica maternal hybrid is higher than the hybrid affinity of the Brassica oleracea hybrid combination.
