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.
