摘　　要：运用灰色关联分析方法,研究20份中国南瓜种的不同农艺性状之间的关系,分析各性状对产量的贡献大小,明确各性状对南瓜育种目标性状影响的主次关系。结果表明:各农艺性状与总产量的关联度大小依次为单株产量、单瓜质量、瓜外横径、侧壁肉厚、第1雌花节位、瓜内腔横径、瓜外纵径、瓜纵径下果肉厚、瓜内腔纵径、种子千粒质量、瓜柄长、瓜柄直径、瓜形指数、瓜纵径上果肉厚。结果表明,以产量作为育种目标应着重从单株产量和单瓜质量,其次从瓜外横径、侧壁肉厚、第1雌花节位等农艺性状进行选育。In this paper, the relationship among different agronomic traits of 20 pumpkin （Cucurbita moschata Duch. ） cuhivars and their contribution to breeding objectives were analyzed with gray relational analysis, to identify the effect of different traits on breeding objectives. The main results were cited as following ： firstly, the biggest association degree of agronomic traits with total yield was the yield per plant, then, followed by weight of single fruit, fruit diameter, flesh thickness of fruit, nodes of first female flower appearance, inner diameter of fruit. It consider that yield as a breeding objective should focus on： the yield per plant, weight of single fruit, fruit diameter, flesh thickness of fruit, and nodes of first female flower appearance, etc.
