摘要 黄瓜嫩果果皮颜色是最重要的商品性状之一,在当前育种目标转向多样化和专用化的过程中引起了人们越来越多的关注。本研究以嫩果果皮颜色不同的3份黄瓜(Cucumis sativus L.)品系为亲本,分别配制2个杂交组合Q16(深绿色)× Q8(黄白色)及Q16 × Q24(黄白色),构建6个世代遗传群体,通过目测与色差仪相结合的方法对6个世代各单株的黄瓜嫩果果皮颜色性状进行观察和分级处理,并应用植物数量性状主基因+多基因模型进行世代联合分析,研究了黄瓜嫩果果皮颜色的遗传规律。结果表明,Q16×Q8和Q16×Q24两个杂交组合中,嫩果果皮颜色性状的分离群体世代呈现单峰或双峰偏态分布,这表明该性状为数量性状且有主基因控制。遗传分析表明,两杂交组合中黄瓜嫩果果色遗传都符合2对主基因的加性-显性-上位性遗传模型(B-1模型);说明黄瓜嫩果果皮颜色性状由 2对主基因控制,在两组合中,其主基因遗传力在F2群体中最高,分别为87.4%和93.1%,另外,两对主基因在两个组合中的加性效应近似相等,分别为1.368、-0.132和1.451、-0.049,两组合中两对主基因的显性效应分别为0.625、1.625和0.529、1.530,两对主基因中第一对主基因加性效应明显,而第二对主基因显性效应明显。两个组合主效基因表现的遗传力较高,表明在杂交育种中对黄瓜嫩果皮色可以进行早代选择。本研究结果为黄瓜嫩果果皮颜色性状的基因定位和新种质创制提供了理论依据。

Abstract:In current, cucumber fruit color is one of the most important commodity characters. When breeding towarded diversity and specialty, it has attracted more and more attention in the process. To study the inheritance of tender cucumber fruit peel color traits, this research used three inbred lines of cucumber(Cucumis sativus L.) which were distinct different in fruit color as the parents material, maked two hybrid combinations, respectively which were Q16(dark green of fruit color)×Q8(yellowish white of fruit color)and Q16×Q24(yellow white of fruit color)and maked six genetic populations (P1, P2, F1, B1, B2 and F2), respectively. And this research adopted the combination of visual and chromatic meter to observe and class for the fruit peel color traits of tender cucumber on each individual plant in six genetics populations. The data of fruit colors were analyzed by joint analysis of multiple generations of the major gene plus poly-genes model of plant quantitative traits. The results showed the generation of segregation population of fruit color traits of cucumber presented unimodal or bimodal skewness distribution in these two hybridized combinations Q16×Q8 and Q16×Q24. This phenomenon indicated that this traits was quantitative traits and part of this traits was controlled by major genes. By the genetic analysis, the results showed that the inheritance of fruit color in these two hybridized combinations (Q16×Q8 and Q16×Q24) were appropriate for the model of two major genes with additive-dominance-epitasis (model B-1). This indicated that fruit color traits of cucumber was controlled by two major genes and the heritability of major genes in two hybrid combinations was highest in F2 population which reached 87.4% and 93.1%, respectively. In addition, the additive effect of two major genes in two hybrid combinations approximately equal which were 1.368, -0.132 and 1.451, -0.049, respectively. And the dominance effect of two major genes respectively were 0.625, 1.625 and 0.529, 1.530 in two hybrid combinations. It could thus be seen that in these two pair major genes, the additive effect of the first pair gene was obvious, and dominant effect of the second for the major gene was notable. In these two crosses, the heritability of major genes was high, this showed that fruit color of cucumber was suited to breeding in earlier generation. This result lay a foundation for the gene location in fruit color traits of cucumber and creating new germplasm of cucumber.
