The possibilities of gene flow from wild Brassica juncea to transgenic glufosinate-and glyphosate-resistant gene oilseed rapes (B.napus) were studied by hand-pollination.The results demonstrated that the indexes of sexual compatibility of glufosinate-tolerant oilseed×wild B.juncea and glyphosate-tolerant oilseed×wild B.juncea were 0.44 and 0.54 respectively,which were significantly lower than that of self-pollination of wild B.juncea.All F1 contained herbicide-resistant gene and exhibited significant resist...
