摘要: 用苦瓜3 个差异显著的自交系为材料, 通过自交、杂交和回交, 获得两个杂交组合(ZH967281 ×G968031 和ZH961123 ×G968031) 的亲本、F1 、F2 、B1 和B2 各世代, 按照数量遗传学理论对其6 个世代群体的第1 雌花节位、单株坐果数、单果质量、果长、果径、果肉厚的遗传效应进行了研究。结果表明: 6 个经济性状的遗传均符合加性- 显性效应模型, 且均以加性效应为主。第1 雌花节位、单株坐果数、单果质量、果长、果径在遗传中表现部分性, 有倾大值亲本的现象。果肉厚表现倾小值亲本的负向超显性。第1 雌花节位、单株坐果数、单果质量、果长、果径、果肉厚的狭义遗传力依次为69. 23 %、61. 94 %、61. 46 %、76. 18 %、28. 98 %和35. 09 %。

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 , F1, F2, 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.
