:1 998～ 1 999年在自然发病条件下对 2 0个花生品种 (系 )进行叶部病害综合抗性鉴定。结果表明 ,目前我国广泛种植的花生品种对晚斑病、早斑病、网斑病等主要叶部病害的抗性存在差异 ,缺乏高抗和兼抗性材料。花生对叶部病害的抗性与主茎高、分枝数、结果数、饱果率等农艺性状及其分类类型无显著相关。自然发病条件下花育 1 7和花育 1 6荚果产量较高 ,引进花生品种 UF91 1 0 8产量较低 ,但对晚斑病、网斑病等具高抗水平 ,可提供花生育种作抗源材料
: From 1998 to 1999, twenty hybrid peanut cultivars (lines) were evaluated for their integrated resistance to leaf disease under natural conditions. The results showed that there are differences in the resistance of the major leaf diseases such as late leaf spot, early spot blotch and net blotch in the peanut varieties widely planted in China, and the lack of high resistant and resistant materials. Peanut resistance to leaf disease and the main stem height, number of branches, the number of results, full fruit rate and other agronomic traits and their classification type no significant correlation. Under natural conditions, the yield of Huayu 1 7 and Huayu 1 6 was higher, and the yield of introduced peanut variety UF91 108 was lower, but had a high level of resistance to late leaf spot and net blotch, providing peanut breeding for resistance Source material
