摘　　要：丹1324玉米自交系于1985年以NN14BHt2为抗源亲本、以Mo17为轮回亲本组建的材料,经过Ht2基因定向回交转育技术、基因诱变技术、不育节养增产技术和田间扩大选择群体与轮回选择等方法选育而成,使多个优良性状集中于一体并使其遗传性得以稳定。丹1324玉米自交系为玉米种质资源创新提供了宝贵的基因资源及应用研究。Dan 1324 is a maize inbred line which was bred in Dandong academy of agricultural sciences. It was bred by using inbred line NN14Bna as the resistant resource and inbred line Mo17 as the backcrossing material through the directional backcrossing transferred technology of gene Ht2, gene inducing mutation technology, male sterile technology, nutrient saving and yield increasing technology, large group selection and backcrossing technology in 1985 and made many super characters gather in one inbred line and made the heredity steady. The breeding of Dan 1324 has provided new and valuable germplasm and technologies for maize breeding.
