Breeding and utilization of male sterile line of cauliflower

摘要: 以3份欧洲花椰菜细胞质雄性不育材料为不育源,用花椰菜小孢子培养的纯系和高代自交系为轮回亲本进行转育,连续回交4代,育成一批综合性状优良、配合力强、雄性不育株率和不育度均达100%的花椰菜胞质雄性不育系及相应的保持系。稳定的不育系用组培快繁技术繁育,并利用该不育系配制一代杂种,经田间鉴定筛选出3个不同类型的优良杂交组合。

Abstract: Some cauliflower cytoplasmic male sterile lines and their maintainer lines were obtained by crossing between three European cauliflower cytoplasmic male sterile materials with pure lines and inbred lines as recurrent parent.The sterile lines showed excellent general characteristics with high combining ability.All rates of sterile plant and sterility reached 100%.The lines were propagated by tissue culture.Three elite hybrids of the combinations crossed with the male sterile lines were obtained through field screening.
