| 摘 要： | 以辣椒胞质雄性不育系8A 及其恢复系F19 为原始材料，利用主基因 + 多基因联合分析方
法对辣椒胞质雄性不育恢复性进行遗传分析。结果表明，辣椒胞质雄性不育恢复性的遗传受两对加性—
显性上位性主基因 + 加性—显性多基因控制。第1 对主基因的加性效应与显性效应分别为0.9314 和
1.1549，均使恢复性增加。第2 对主基因的加性效应与显性效应分别为–0.5276 和–0.1930，均使恢复性
降低。多基因的加性效应与显性效应分别为–2.4038 和0.1036。主基因的遗传率高达97.57%，表现出很
高的遗传力，说明在早期世代就可对恢复性进行有效选择。

| Abstract: | In this study，hybrid of combination of pepper（Capsicum annuum L.）were made with
cytoplasmic male sterility line 8A and it’s restorer line F19. In addition to F1 and F2，two parents were used
to explore the restorer genetic pattern of cytoplasmic male sterility by mixed model of major gene plus
polygene. The results showed that the restoration of cytoplasmic male sterility was controlled by two
major additive-dominant epistasis genes and additive-dominant polygenes. The additive effects and the
dominant effects of the first major gene make the restoration add with a value of 0.9314 and 1.1549
respectively，and that of the second major gene make the restoration descend with a value of–0.5276 and
–0.1930 respectively. The absolute values of the first major gene’s effects were higher than that of the
second major gene apparently. The value of additive effects and dominant effects of polygene were
–2.4038 and 0.1036 respectively，the dominant effects make the restoration add and the additive effects
make the restoration descend. Two major genes exhibited a good heritability with a value of 97.57%，it was
indicated that the restoration could be selected in early generations. |
