摘　　要：对不同生态类型的50份黄瓜种质资源的单瓜种子产量进行检测,并对单瓜种子产量与种瓜性状进行相关分析。结果表明,黄瓜单瓜种子产量在品种间存在一定的差异,变幅在0.5-7.9 g之间;筛选出单瓜种子产量在6.2 g以上的高产黄瓜种质资源5份,单瓜种子产量在1.9 g以下的低产黄瓜种质资源5份。黄瓜单瓜种子产量与7个性状相关,其影响顺序为：单瓜籽粒数〉心腔横径〉百粒重〉单瓜重〉种子长〉种子宽〉心腔纵径。通径分析表明,单瓜籽粒数和百粒重是影响黄瓜单瓜种子产量的主要因素,直接通径系数分别为0.908、0.363。此外,4种生态类型之间的单瓜种子产量差异不显著。In this study, the seed yield per fruit and the fruit traits of 50 accessions of different types of cucumber（ Cucumis sativus L. ） were tested,and correlation and path analysis with characteristics of cucumber was carried out. The results showed that there were obvious variances of the seed yield per fruit in different varieties of cucumber germplasm, swinging in the range of 0.5 - 7.9 g. The output of five accessions was more than 6.2 g and 5 accessions was less than 1.0 g. The order of 7 related traits influence on the seed yield per fruit was as follows： number of seed per fruit 〉 fruit chamber diameter 〉 hundred-seed weight 〉 per fruit weight 〉 seed length 〉 seed wide 〉 fruit chamber length. Multiple regression analysis and Path analysis both showed number of seed per fruit and hundred-seed weight were the major factors to affect the seed yield per fruit, and the direct path coefficient were 0. 908,0. 363, respectively. In addition, between the four ecological types, per fruit seed production variance analysis was not significant.
