从甘蓝型油菜品种群体中或是从杂交后代中发现自交不亲和(SI)个体,目前仍是采用大量套袋自交方法检定。这种方法比较繁琐而且又不易保留真正的SI个体。所以,重要的是找到一个与SI性状紧密连锁的标志性状。国外Thompson M.M.〔1〕和Hermson J.G.〔2〕曾分别发现榛子树和马铃薯的SI性与色素的连锁关系。在甘蓝型油菜上是否也有这种连锁关系?1985年我们以SI系“白花”(白)为母本与两个黄花(黄)自交亲和(SC)品种ww
Self-incompatibility (SI) individuals have been found in populations of B. napus breeds or from crossbreds and are still being assayed using a large number of bagging self-intrinsics. This method is more complicated and difficult to retain the real SI individuals. So, it is important to find a signature that is closely linked to the SI trait. Overseas Thompson M.M. 〔1〕 and Hermson J.G. 〔2〕 have been found in hazelnut and potato SI sex and the relationship between the pigment. Is there such a linkage in Brassica napus? In 1985 we used the SI Department “white flower” (white) as the female parent and two yellow (yellow) self-compatible (SC) varieties ww
