近几年来,随着抗病育种的大力开展,对病害抗性的遗传研究也愈来愈被人们所重视。人们在抗性遗传研究中应用了水平抗性和垂直抗性,并认为水平抗性的遗传一般是多基因控制的。有人还认为,水平抗性在多数情况下是由几个基因控制的。强度通常是数量特征。Smith等曾推断美国烟草品种青枯病抗性遗传由多个隐性基因控制;Segneira等曾证明马铃薯青枯病抗性遗传有十个主基因之多。花生青枯病为腐生性较强的细菌性病害,寄
In recent years, with the vigorous development of disease-resistant breeding, genetic research on disease resistance has also been paid more and more attention. Horizontal resistance and vertical resistance have been used in resistance inheritance studies, and the inheritance of horizontal resistance is generally controlled by polygenes. Some people also think that the level of resistance in most cases is controlled by several genes. Strength is usually a quantitative feature. Smith et al. Concluded that the inheritance of resistance to bacterial wilt bacterial wilt in the United States is controlled by a number of recessive genes; Segneira et al. Have demonstrated that potato bacterial wilt resistance has as many as ten major inheritance. Peanut bacterial wilt is a saprophytic bacterial disease, send
