Abstract: The hot pepper CMS 21A, sweet pepper CMS 8A and 9 different genotype fertility restoring lines were used to study the inheritance of fertility restoring genes. The results showed that Xiong 804, LS7, Xiangzi, Luozi, SI201, translated R-gene sweet pepper and hot pepper inbreds were fully restoring lines to CMS 21A and 8A and possessed a pair of dominate restoring genes. The restoring genes in Xiangzi, Luozi and translated R-gene hot pepper were allele, but non-allele in SI201. Nanchang 92-1 and Luotian No.2 were partial restoring lines to CMS 21A and 8A and there were differences in the fertility restoring rates. 414 combinations were made between CMS lines (21A, YanA and 8A) and 138 inbreds (hot and sweet pepper). Fertilities in 102 of them were fully restored, 146 partially restored and 166 unrestored. Among the fully restored combinations, 82.4% were hot pepper restoring lines, but only 17.6% were the sweet pepper restoring lines. It suggested that the restoring genes were mainly distributed in the hot pepper (inbreds).
