花生的叶部病害被农学家认为是减少花生经济收入的主要病害之一,特别是叶斑病和锈病,在没有进行化学防治的地方,荚果产量损失可高达50％,如果使用了农药防治,估计也要减少10％(Mixon and Hammons,1983)。况且大批量的施用农药,不仅投资大,而且容易造成环境污染,因而从遗传角度鉴定和利用抗病种质,培养抗病品种已成为日益重要的研究项目。近年来,许多科学家(Subrahmanyam,1980,1983,1985;Singh,
Peanut leaf disease is considered by agriculturalists as one of the major diseases to reduce the economic income of peanuts, especially leaf spot and rust. Where there is no chemical control, pod yield loss can be as high as 50%. If pest control is used, It is also estimated to have decreased by 10% (Mixon and Hammons, 1983). In addition, the large-scale application of pesticides is not only a big investment, but also easy to cause environmental pollution. Therefore, identification and utilization of disease-resistant germplasm and cultivation of resistant varieties have become increasingly important research projects from a genetic perspective. In recent years, many scientists (Subrahmanyam, 1980, 1983, 1985; Singh,
