摘要: 以2 个嫩果皮颜色不同的黄瓜自交系为试验材料,通过目测分类、色彩色差仪测定果皮色L
值和C 值,并利用P1、P2、F1、B1、B2 和F2 等6 个世代联合分析方法,研究了黄瓜嫩果皮颜色的遗传规
律。结果表明:黄瓜嫩果皮颜色性状符合两对加性—显性—上位性主基因 + 加性—显性—上位性多基
因模型(E-0 模型);L 值和C 值F2 代主基因遗传力分别为93.61%和80.86%,遗传力较高;多基因遗传

Abstract: Hybrid combinations of cucumber(Cucumis sativus L.)were made with two inbred lines
with different immature fruit skin color. The C and L values of immature fruit skin color were measured by
color difference meter after visually classified. The generations of F1,F2,backcrosses B1 and B2 and their
parents P1 and P2 were used to explore the inheritance of immature fruit skin color traits with the method
of conjoint analysis. The results showed that the major gene and polygene(E-0 model)inheritance of
immature fruit skin color in cucumber accorded with the additive-dominance-epitasis pattern. The L value
and C value of major gene heritability in F2 are 93.61% and 80.86% respectively. The major gene
heritability in F2 is higher while the polygene heritability and environmental effect are lower,so we
suggest that the fruit skin color breeding of cucumber should be selected in the early generation.
