通过对3381份(国内2257,国外1124份)花生种质资源的田间自然病圃和人工接种鉴定,共获得高抗花生青枯病的种质资源55份,中抗43份。其中国内资源高抗的50份,中抗的39份,国外资源高抗的5份,中抗4份。不同类型的资源以及同一类型不同地区来源的资源其抗性表现差异极大。并筛选出一批经济性状优良的高抗种质。
A total of 553 germplasm resources with high bacterial resistance to peanut bacterial wilt were obtained through field natural inoculation and identification of 3381 peanut germplasm resources (2257 domestic and 1124 foreign). Among them, 50 are highly resistant to domestic resources, 39 are moderate resistance, 5 are highly resistant to foreign resources and 4 are anti-resistance. Different types of resources and resources from different regions of the same type have very different resistance performance. A number of high-resistant germplasms with good economic traits were selected.
