本研究采用植物数量性状主基因+多基因混合遗传模型多世代联合分析方法，对耐褐变丝瓜( P1)与易褐变丝瓜( P2)构建的P1、P2、F1、B1、B2和F26个群体果肉褐变特性进行分析。结果显示，普通丝瓜果肉耐褐变遗传符合2对加性-显性-上位性主基因+加性-显性-上位性多基因混合遗传模型(E 0)。其中B1、B2和F2的主基因遗传率分别为50.00%、50.00%和62.27%，多基因遗传率分别为40.07%、42.04%和31.63%，环境方差占总表型方差的6.10%~9.93%。

Six populations (P1, P2, F1, B1, B2 and F2) derived from the cross of anti-browning germplasm(P1) and browning germplasm( P2 ) in luffa were used to study the inheritance of anti-browning by the mixed major-gene plus pol-ygene inheritance model with joint analysis method of multiple generations. The inheritance of anti-browning of luffa fitted two pairs of additive-dominance-epitasis major genes plus additive-dominant-epitasis polygene model ( E 0 ) . The major gene heritabilities of B1 , B2 and F2 were estimated to be 50. 00%, 50. 00% and 62. 27%, respectively, and the polygene heritabilities to be 40. 07%, 42. 04% and 31. 63%, and the environmental variance accounted for 6. 10%-9. 93% of phe-notype variance.
