摘    要: 以新疆厚皮甜瓜‘76-2’的60Co- γ射线诱变酸味突变自交系和‘黄皮脆’形成的P1、P2、F1与F2 为试验材料,通过4个世代联合分析法研究果实中糖含量、酸含量和糖酸比的遗传特点。结果表明, 酸味突变自交系ב黄皮脆’组合的糖含量性状遗传受两对等加性主基因和加性显性多基因模型 (E-4) 控制,主基因遗传率为88.8%,多基因遗传率为6.94%;酸含量性状遗传受一对加性—显性主基因和加性—显性上位性多基因 (D-0)模型控制,主基因遗传率为26.68%,多基因遗传率为72.77%;糖酸比性状遗传受两对加性—显性—上位性和加性—显性多基因混合遗传模型(E-1)控制,主基因遗传率为82.86%,多基因遗传率为16.02%。

Abstract:Four generations of P1, P2, F1 and F2 were used to study the inheritance of melon sugar content、sour content and sugar acid radio traits in mutation inbred line with sour taste (76-2 by 60Co- γ irradiation) and 'Huangpicui' by joint analysis method of multiple generations. The results showed that the sugar content was controlled by two pairs of equal additive major genes plus additive-dominant polygene (E-4 model). The major gene heritability is 88.8%; the polygene heritability is 6.94%. The inheritance of sour content fitted one pair of additive-dominance major gene plus additive-dominance-epitasis polygene (D-0 model). The major gene heritability is 26.68%; the polygene heritability is 72.77%. Sugar acid radio trait fitted two pairs of additive-dominance-epitasis major genes plus additive-dominant polygene (E-1 model). The major gene heritability is 82.86%; the polygene heritability is 16.02%.
Keywords:melon  sugar acid radio  genetic
