关于小麦赤霉病遗传问题,国内外尚无定论。据意大利报导,硬粒小麦吉阿多512对赤霉病免疫,并认为抗病是由一对基因控制的显性遗传。但该品种引入我国试种,表现为感病。日本有人认为,小麦赤霉病受3对基因控制。国内也有资料报导,抗病为隐性,感病为显性。我们据几年的研究,初步认 About the genetic problem of wheat scab, there is no conclusion at home and abroad. According to reports from Italy, the durum wheat Jiaduo 512 was immunized against the scab and considered the disease resistance to be dominated by a pair of genes. However, the species introduced into China’s trial, manifested as susceptible. Some people in Japan believe that wheat scab belongs to three pairs of genes. There are also domestic data reported that disease resistance as recessive, susceptible to dominant. According to several years of research, we initially recognize
