Abstract 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.
