Abstract:: The heat tolerant parents (L1 and L3)，susceptible parents (L6 and L4) and their reciprocal crosses F1 and F2 generations were used to analysis of the inheritance of heat tolerance in bottle gourd.The phenetic data of relative germination rate (ΔG)，relative germination index (ΔGI) and relative conductivity of seedling (ΔEC) were collected and analyzed by ‘Compare Means’ function of SPSS software.The results showed that the inheritance of heat tolerance of bottle gourd was controlled by the recessive gene and the maternal hereditary was not detected.The ‘Chi-square test’ of F2 generations results fit to the expected chi-square value of 1∶3，which suggested the heat tolerance of bottle gourd was controlled by one pare single gene.
