Abstract：Inheritance of plant type traits of summer squash（Cucurbita pepo L.）in P1, P2, F1, B1, B2 and F2 from two crosses q-1×23-4G（cross 1）and q-1×A-7（cross 2）was investigated by major gene and polygene mixed inheritance model of quantitative traits. The results showed that the plant type traits were both controlled by B-1 model; genetic effect of plant height of two crosses were mainly additive effect, but genetic effect of leaf number of two crosses were mainly additive effect and dominant effect. Heritability values of the major genes of F2 were relatively high and environmental effect was relatively low. These results indicated that plant type traits breeding of summer squash should be selected in early generation and the conventional cross breeding would be more effective for the improvement of plant type traits in summer squash.
