摘要: 基因型为N(MsMs)、S(MsMs)的材料可直接做恢复系;基因型为N(msms)的优良自交系材料可采用胞质雄性不育三系配套杂交种为母本,与原材料为转回亲本,经回交3~5代,再自交2代,连续2代全恢复的株系为新恢复系;N(Msms)、S(Msms)2种基因型后代CMS基因型和植株特征特性都会出现分离,选全恢复的株系经自交纯化后为新的恢复系。并成功利用此技术转育6份恢复系。

关键词: 辣椒, 胞质雄性不育, 恢复系, 转育

Abstract: Breeding materials of N(MsMs)or S(MsMs)genotypes can be used as restorers directly.Excellent inbred lines which have N(msms)genotypes can be used as back-cross parents to get new restorers if they can restore fertility in recent 2 generations continuously by crossing with the CMS F1,then back-crossing 3-5 generations,selfing 2 generations at last.The fertility restore offsprings of N(Msms)or S(Msms)genotypes willl be new restorers by selfing.We transformed 6 restorer lines successfully.

Key words: Pepper, Cytoplasmic male sterility, Restores line, Transformation
