以果实口感无酸味的甜瓜材料60和酸甜味的材料61为亲本，构建P1、P2、F1、BC1、BC2及F2六世代群体，利用主基因+多基因混合遗传模型的六世代联合分析法，分析甜瓜果实柠檬酸含量、可滴定酸值（TA）和pH值的遗传效应。结果表明：柠檬酸含量的遗传模型为1对加性-显性主基因+加性-显性-上位性多基因模型，F2群体的主基因遗传率为31.06%，多基因遗传率为30.48%；TA值的遗传模型为2对加性-显性-上位性主基因+加性-显性-上位性多基因模型，F2群体的主基因遗传率为78.06%，多基因遗传率为0；pH值的遗传模型为1对加性-显性主基因+加性-显性-上位性多基因模型，F2群体的主基因遗传率为84.07%，多基因遗传率为12.90%。

Six generations of P1,P2,F1,BC1,BC2 and F2 derived from a crossing between parent‘60’(acidless)and‘61’(acid)were used to study the hereditary effects of melon fruit in citric content,titratable acidity(TA)and pH value by the mixed major gene plus polygene inheritance model with joint analysis method of multiple generations.The results showed that the genetic model of citric content was“one pair of additive-dominant major gene plus additive-dominant-epistasis polygene”. Heritability of the major gene and polygene in F2 population was 31.06% and 30.48%,respectively. Genetic model of TA was“two pairs of additive-dominant-epistasis major gene plus additive-dominant-epistasis polygene”.Major gene heritability of TA in F2 population was 78.06%,while that of polygene was 0.The genetic model of pH value was also“one pair of additive-dominant major gene plus additive-dominant-epitasis polygene”,and the major gene heritability in F2 was 84.07%,while that of polygene was 12.09%.
