摘　　要：番茄的颜色和色素含量是决定果实品质的两个重要特性。在本研究中,使用绿色和紫色番茄植株分别作为母本和父本,分别产生了6个遗传群体,即P1、P2、F1、BC1、BC2和F2。通过数量性状的多代联合分析研究果实颜色和色素含量的遗传规律。结果表明,绿色和紫色果之间的果实颜色的最佳遗传模型为MX1-AD-ADI。BC1、BC2和F2代色度值的主基因遗传率分别为82%、59%和77%,多基因遗传率分别为8%、10%和13%。番茄红素含量的遗传符合MX2-ADI-AD模型,BC1、BC2和F2的主基因遗传率分别为64%、74%和93%,而多基因的遗传率分别为20%、0%和0%。叶绿素的遗传模型为MX1-AD-ADI,BC1、BC2和F2的主基因遗传率分别为59%、74%和59%,多基因的遗传率均为0%。胡萝卜素的遗传符合MX2-ADI-ADI模型,BC1、BC2和F2的主基因遗传率分别为76%、4%/5%和54%,而多基因的遗传率分别为0%、0%和13%。The color and pigment content of tomato are two important characteristics that determine fruit quality.In this study, green and purple tomato plants were used as female and male parents, respectively, to make six genetic groups, namely P1, P2, F1, BC1, BC2, and F2. The genetic rule of fruit color and pigment content was studied by multi-generation joint analysis of quantitative traits. The results showed that the best genetic model of fruit color between green and purple fruits was MX1-AD-ADI. The heritability of the major genes of BC1, BC2, and F2 generations was 82%, 59%, and 77%, respectively, while the heritability of multiple genes was 8%, 10%, and 13%, respectively. The inheritance of lycopene content was consistent with the MX2-ADI-AD model, the heritability of the major genes of BC1, BC2, and F2 were 64%, 74%, and 93%, respectively, whereas the heritability of multiple genes was 20%, 0%, and 0%, respectively. The genetic model of chlorophyll was MX1-AD-ADI, and the heritability of BC1, BC2, and F2 were 59%, 74%, and 59%, respectively. The heritability of multiple genes was 0%. The inheritance of carotene conformed to the MX2-ADI-ADI model, the heritability of the major genes of BC1, BC2,and F2 were 76%, 4%/5%, and 54%, respectively, while the heritability of multiple genes was 0%、0%, and 13% respectively.
