摘　　要：我国甜瓜种质资源丰富,为了有效地保护和利用甜瓜资源,本研究调查分析了25份露地栽培甜瓜种质资源果实性状,结果表明25份甜瓜种质资源中,果实质量性状的多样性指数在0.00~1.98之间,变异系数在0.00%~59.20%之间。其中果皮底色的多样性指数最大,为1.98,变异系数为53.45%;果实形状次之,为1.68,变异系数为54.94%。数量性状的多样性指数在1.73~1.94之间,变异系数在2.67%~61.04%之间,其中总酸的多样性指数最高,为1.94,变异系数为20.09%。通过对果实的数量性状进行聚类分析,可将25份甜瓜种质资源分为5类,其中第Ⅳ类种质资源的可溶性蛋白、总酸、可溶性糖含量的平均值在5个类群中均最大。综上所述,参试甜瓜种质资源果实农艺性状具有丰富的多样性,可为甜瓜种质资源创新、新品种选育提供理论依据。China has abundant germplasm resources of cantaloupe.In order to effectively protect and utilize melon germplasm resources,this study investigated and analyzed the fruit traits of 25 open field cultivated melon germplasm resources.The results showed that the diversity index of fruit quality traits ranged from 0.00-1.98,and the coefficient of variation ranged from 0.00%-59.20%.The diversity index of the background color of the fruit peel is the highest,at 1.98,with a coefficient of variation of 53.45%;The shape of the fruit is second,with a coefficient of variation of 54.94%and a value of 1.68.The diversity index of quantitative traits ranges from 1.73-1.94,with a coefficient of variation between 2.67%-61.04%.Among them,the diversity index of total acids is the highest,at 1.94,with a coefficient of variation of 20.09%.Cluster analysis was conducted on the quantitative traits of fruits,and 25 melon germplasm resources were divided into 5 categories.Among them,theⅣcategory had the highest average content of soluble protein,total acid,and soluble sugar among the 5 groups.In summary,the fruit agronomic traits of the tested melon germplasm resources have rich diversity,which can provide a theoretical basis for the innovation of melon germplasm resources and the breeding of new varieties.
