摘要
本文总结了“六五”和“七五”期间,对4000多份花生种质资源抗锈性的鉴定结果。国内资源2508份,表现高抗和中抗的分别为21份和237份;国外资源1644份,表现高抗和中抗的分别为234和188份。不同类型的品种以及不同地区来源的花生品种,其抗性表现不同,即使是同一品种,在不同国家和地区,其抗性表现也不完全一致,本试验还从珍珠豆型花生品种中鉴定出抗锈资源,并首次对龙生型花生进行抗锈性鉴定。
More than 4000 groundnut germplasm accessions were screened for resistance to rust during 1981 to 1990 in China. From the 2508 lan-draces screened, 21 and 237 showed high and moderate resistance respectively.From the 1644 exotic lines, there were 234 with high or moderate resistance to the disease. The percentages of resistant accessions in different botanic types and even in groups from different regions were different. However, there was some differences of diseasereactions among different countries or regions, Rust resistance in Chinese Dragon groundnut (var.hirsuta )was first reported.
