摘要
耐冷玉米自交系是耐冷玉米品种选育的关键,为提供耐冷玉米品种的选育材料,以不同遗传背景的100份玉米自交系为试验材料,通过发芽期耐冷性筛选、幼苗期耐冷性筛选、低温下相对电导率测定、低温下抗氧化保护酶活性分析等试验,筛选得到相对耐冷性强的玉米自交系4份。
Cold tolerance maize inbred lines is the key to the cold tolerance maize variety breeding. In order to provide the material support for the cold tolerance maize variety breeding,taking 100 maize inbred lines with different genetic background,the cold resistance screening in germination period,the cold resistance screening in seedling stage,the relative electrical conductivity measurement and protective enzyme activity analysis under low temperature were studied. The results showed that four relatively cold resistance of maize inbred lines were obtained.
