Abstract: The genetic effects of node of 1st female flower , fruit number per plant , individual fruit weight , fruit length , fruit width , pulp thickness in Momordica charantia L. were analysed on the data from the parents , F_1, F_2, B₁ and B₂ of two cross as ( ZH967281 ×G968031 and ZH961123 ×G968031) by using three inbred lines with significant difference. The results showed that genetic patterns of six economic characters all accorded with the pattern of additive-dominance and additive effect was major. Node of 1st female flower , fruit number per plant , individual fruit weight , fruit length and fruit width were all positive dominance partially and tended to the larger parent , but
pulp thickness was negative hyperdominance and tended to the smaller parent . The narrow heritability of node of 1st female flower , fruit number per plant , individuam fruit weight , fruit length , fruit width and pulp thickness were 69. 23 % , 61. 94 % , 61. 64 % , 76. 18 % , 28. 98 % , 35. 09 % ,
respectively.
