In this paper,the relationship among different agronomic traits of 20 pumpkin（

Cucurbita moschata Duch.）cultivars 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.
