摘要: 1995-1996年,对我国育成的有代表性的5个抗病品种进行抗枯萎病基因的等位性测定。结果表明:在所选用的5个抗病品种中至少存在两个不同的抗病基因(暂定名为Fwl和Fw2)。连锁分析显示:Fwl与T586的8个标志性状间、Fw2与T582、T586的13个标志性状间无连锁关系。
Abstract:Allelism in vestigation of genes resistante to Fusarium wilt in cotton suggested that there were 2 genes(assigned symbols Fw1 and Fw2)in 5 cultivars used.No linkage was found between Fw1 and the marker genes in T586 and between Fw2 and those marker genes in T582 and T586.
