花生叶斑病是我国花生产区的一种普发性病害,一般减产4—15％,严重可达30％以上。花生叶斑病抗源的筛选工作,始于70年代,国际半干旱研究所及美国已筛选出了一批具有抗性水平的品种材料,并已用于抗病育种中。我国目前正在开展这方面的工作。1987—1988连续两年我们对932份花生品种资源进行了田间筛选鉴定,并获得了一批抗性材料。
Peanut leaf spot is a generalized disease in China’s flower-producing area, with a general decrease of 4-15% and a severe up to 30%. Screening of peanut leaf spot resistance sources began in the 1970s, and a number of resistant materials were screened by the IARC and the United States and used in resistance breeding. My country is currently carrying out this work. 1987-1988 For two consecutive years, we identified 932 peanut germplasm resources and obtained a batch of resistant materials.
