摘要
摘 要 为探究辣椒株高与主茎长的遗传规律,以辣椒矮杆材料C152为母本,高杆材料A37为父本,构建P1P2、F1和F2四世代遗传群体,采用植物数量性状"主基因+多基因"混合遗传模型分析法对株高和主茎长进行多世代联合分析.结果表明:辣椒株高遗传受两对加性主基因+加性-显性多基因控制,第1对主基因加性效应值为32.803 8,第2对主基因加性效应值为19.653 5,主基因遗传率为91.83％;辣椒主茎长遗传受两对等显性主基因+加性-显性多基因控制,主基因加性效应值为-4.052 4,遗传率为55.69％.
Abstract
This study investigates the genetic mechanisms of plant height and main stem length in chili pepper.Four generations of genetic populations,namely P1,P2,F1,and F2,were developled using the dwarf accession C152 as the maternal parent and the tall material A37 as the paternal parent.Ge-netic analysis was conducted using a mixed inheritance model that integrates major gene and polygenic effects.The results demonstrated that the inheritance of plant height in chili pepper was regulated by two pairs of additive major genes along with additive-dominant polygenes.The additive effect value of the first pair of major genes was 32.803 8,and the additive effect value of the second pair of major genes was 19.653 5,and the heritability of the major gene was 91.83％.In contrast,the main stem length was regulated by two equal additive major genes plus additive dominant polygenes,with an ad-ditive effect value of-4.052 4 and a major gene heritability of 55.69％.
