摘　　要：为了对‘金蜜六号’甜瓜重要农艺性状进行改良,利用‘金蜜六号’父、母本材料杂交构建F_2分离群体,得到496株个体,对果皮底色、果肉颜色等14个性状进行调查、评价和分析。结果表明,果皮底色、果面网纹密度、果肉颜色和果肉质地4个农艺性状的分离比约为3∶1,为单基因控制的质量性状;叶长、叶宽、果柄粗度等7个性状指标都呈正态分布,说明这些性状是数量性状。除边部可溶性固形物含量和中心可溶性固形物含量外,其余7个性状都和果实质量具有极显著的相关性。回归分析表明,果肉厚度对果实质量的形成作用最大,可为甜瓜高产育种提供理论基础。In order to improve important agronomic traits of ‘ Jinmi No. 6 ＇ of melon, the F2 segregating population was constructed by hybridization of male and female parent materials of ‘Jinmi No. 6＇ and 496 individuals were obtained. A total of 14 agronomic traits such as primary skin color and flesh color were investigated. The results showed that the separation ratios of 4 agronomic traits including primary skin color, density of rind netting, flesh color and flesh texture were all about 3 ： 1, indicating the single gene controlled qualitative trait. A total of 7 traits such as leaf length, leaf width and pedicel diameter were normally distributed, indicating the quantitative trait. Except for the content of marginal soluble solids and central soluble solids, the other 7 traits and fruit weight were significandy correlated. The regression analysis showed that flesh thickness had the biggest effects on the formation of fruit weight and leaf length had a negative effect on the formation of fruit weight, which could provide theoretical basis for the high-yield breeding of melon.
