Abstract: Six generations (P1, P2, F1, F2, B1, B2) of cucumber were tested to characterize inheritance of heat tolerance based on heat injury symptom. The results indicated that the inheritance of heat tolerance in cucumber agreed with the additive and dominant model, and the additive component was predominant. Both broad sense herilability and narrow sense heritablity were relatively high. An incomplete dialer cross between three heat tolerant parents and four heat sensitive parents was also analyzed for heat tolerance. The results revealed that variation of GCA was more significant than variance of SCA.

Key words: Cucumber, Heat tolerance, Genetic model, Heritability
