摘 要 :芸薹属内遗传和变异类型极其丰富,这为芸薹属植物种间杂交提供了条件。通过甘蓝(B. oleracea,2n=CC=18)和芥菜型油菜(2n=AABB=36)的种间杂交可以获得六倍体新物种,为油菜育种创造新的种质资源。本文选用芥菜型油菜和黄籽羽衣甘蓝(B. oleracea var. aceaphala,2n=CC=18)进行种间杂交,在10个杂交组合中,共授粉559朵花,
Abstract:There are abundant genetic types available for making interspecific hybrids in Brassica. New sextuploid species (2n=AABBCC=54) can be obtained through interspecific hybridization between Brassica juncea (2n=AABB=36) and Brassica oleracea (2n=CC=18). 10 crosses between B. juncea and B. oleracea var.
