摘　　要：高粱雄性不育系吉2055A是吉林省农业科学院作物资源研究所以A_(1)型保持系314B作为母本,以印度高粱类型且对A_(1)型胞质恢复的871300为父本,经人工去雄杂交、自交、定向选择、回交转育等方法选育而成,该不育系具有不育性稳定、适应性广、抗逆性强、配合力高等特点,2009年申请国家植物新品种权,2015年获得授权。高粱雄性不育系吉2055A的成功选育,增加了吉林省高粱新资源类型,由其组配的多个高粱新品种均在北方春播早熟区生产中广泛应用。The sorghum male sterile line Ji 2055A was bred by the institute of crop resources of Jilin Academy of Agricultural Sciences with the A_(1) maintainer line 314B as the female parent and the Indian sorghum type 871300 recovered for the A_(1) cytoplasm as the male parent.It was bred by the methods such as artificial remove stamen,hybridization,directional selection,and backcrossing.This sterile line has the characteristics of stable sterility,wide adaptability,strong stress resistance,and high combining ability.It was applied for a new national plant variety in 2009 and got it in 2015.The successful selection and breeding of sorghum male sterility line Ji 2055A has increased new sorghum resource types in Jilin Province,and many new sorghum varieties assembled by it have been widely used in production in spring sowing early maturity areas in the north.
