摘要:

【目的】利用F2代临时自交系的辣椒果实分析辣椒素和辣椒色素的遗传规律,探究F2代性状分离比,为培育高辣椒素、高辣椒色素含量的辣椒以及种质资源的创制提供理论依据。【方法】通过亲本杂交产生F1代群体,及F1代单株自交,构建F2代世代群体。分析F2代群体的辣椒素、辣椒色素性状,研究辣椒素、辣椒色素性状遗传规律。【结果】辣椒果实中辣椒素类物质变异系数均在60%以上,辣椒色素的变异系数为28.45%。F2代群体中以母本作参照辣椒果实中辣椒素的分离比为26∶1,辣椒色素的分离比为1∶1,辣椒素的分离比为35∶13∶5∶2∶1。【结论】可以利用种间杂交创制种质资源以及培育高辣椒素和高辣椒色素品种,影响辣椒果实中的辣椒素和辣椒色素的基因位点并不止一个。

Abstract:

【Objective】 To analyze the genetic patterns of capsaicinoids and carotenoids in chili fruits by using F2 generation self-pollinated lines, investigate the segregation ratios of traits in the F2 generation, and provide theoretical basis for breeding high-capsaicinoid and high-carotenoid chili varieties and creating germplasm resources. 【Methods】 By crossing parental lines to produce an F1 population, followed by single plant self-pollination of the F1 generation to establish the F2 generation population. The capsaicinoids and carotenoids contents in the F2 population were analyzed according to national standards, and the genetic patterns of these traits were studied. 【Results】 The coefficient of variation for capsaicinoid substances in chili fruits was over 60%, while for carotenoids it was 28.45%. In the F2 population, using the maternal line as a reference, the segregation ratio for capsaicinoids was 26∶1, for carotenoids it was 1∶1, and for capsaicinoids it was 35∶13∶5∶2∶1. 【Conclusion】 Interspecific hybridization can be used for creating germplasm resources and breeding high-capsaicinoid and high-carotenoid varieties; however, multiple gene loci influence the levels of capsaicinoids and carotenoids in chili fruits.
