Abstract
[Objective] The aim was to study the inheritance of pulp thickness, so as to provide a theoretical basis for breeding summer squash variety with thicker pulp. [ Method] Using mixed major gene and polygene inheritance model, a joint analysis of six generations from two crosses q-1 ×23-4G( cross 1) and q-1 × A-7 (cross 2 ) was conducted to investigate the inheritance of the pulp thickness of summer squash. [ Result] The results showed that the pulp thickness was controlled by D-2 model( a pair of additive major gene plus additive-dominant polygene) ; generic effect of pulp thickness in the two crosses was mainly the polygene dominant effect. Heritability values of the genes of F2 generation was relatively low, while the environmental effect was high. [ Conclusion ] To pulp thickness, the method of individual selection on high separated generations was effective in the breeding of summer squash with thick pulp.关键词
