摘　　要：对５７００份花生种质资源的植物学性状和经济性状、抗病性和种子品质性状进行了鉴定评价，筛选出高抗锈病种质９２份，高抗早斑病种质７７份，高抗晚斑病种质５３份，高抗根结线虫资源３份，高抗青枯病资源１０２份，抗锈病兼抗早斑病资源５８份，抗锈病兼抗晚斑病资源４９份，抗锈病兼抗早、晚斑病资源４５份，抗青枯病兼抗根结线虫资源２份，抗青枯病兼抗锈病资源１份。蛋白质含量达３４％以上的３３份，含油量达５８％以上的２４份，油酸含量达６７％以上的１８份，亚油酸含量达４７％以上的１５份。不同类型不同来源的花生品种的植物学性状、经济性状、抗病性和种子品质性状均有显著差异。The botanical and economic characters,resistance to diseases and seed quality of 5700 groundnut germplasm accessions were investigated and evaluated. Ninety two accessions were identified with rust resistance,77 accessions with early leafspot resistance,53 accessions with late leafspot resistance, 3 accessions with root knot resistance,102 with bacterial wilt resistance, 58 accessions with rust and early leafspot resistance, 49 with rust and late leafspot resistance, 45 accessions with rust ,early and late leafspot resistance, 2 accessions with root knot and bacterial wilt resistance,and 1 accession with rust and bacterial wilt.The result of testing seed quality indicated that there were 33 accessions with protein content more than 34%, 24 accessions with oil content more than 58%, 18 accessions with oleic acid more than 67% and 15 accessions with lineoleic acid more than 47%. There are significant differences in botanical and economic characters, resistant to diseases and seed quality characters among the different botanical groundnut types and different ecological regions where local germplasm was collected.
