【摘要】 以西瓜为试材,采用2种鉴定方法研究了18份种质资源的枯萎病抗性情况。结果表明:供试种质中没有西瓜枯萎病免疫的品种。苗期人工接种法鉴定出高抗西瓜枯萎病材料9份,占参试材料50%;抗病材料1份,感病材料4份,高感病材料4份。其中高抗材料中K1和K4死苗率最低为2%,比高抗对照品种Sugarlee死苗率低。用分子鉴定的方法鉴定出抗病材料6份。苗期田间接种鉴定和分子鉴定结果吻合率达到66.67%。更多还原

【Abstract】 Watermelon was used as test material,Fusarium wilt resistance of 18 watermelon germplasms were identified by two methods.The results showed that immune varieties were not found in tested material.9 cultivars were high resistance,accounted for 50%;1 cultivar was resistance;4 cultivars were susceptibility;4 cultivars were high susceptibility.Dead seedingsrate of K1 and K4 were 2%,less than the sugarlee control cultivars.6 cultivars showed resistance by using molecular identification.The coincident rate of artificial inoculation at seedling stage and molecular identification was 66.67%.更多还原
