摘　　要：为了明确东北北部常用玉米自交系遗传基础,更好地改良和利用玉米种质,利用70对玉米SSR引物,对131个东北北部常用自交系和6个标准测验种共137个自交系进行遗传多样性分析。结果表明:将PA、BSSS和LRC划为A群,PB、Lan和SPT归为B群,有61个自交系属于A群,50个属于B群,中间型26个。In order to define the genetic basis of maize inbred lines, the genetic diversity of 131 maize inbred lines in the north of northeastern of China and 6 tests was analyzed by simple sequence repeat（SSR）. Seventy pairs of primers of maize were used. The results showed that if PA, BSSS, LRC were group A, PB, Lan, SPT were group B,61 inbred lines belonged to group A,50 inbred lines belonged to group B, and there were 26 inbred lines belong to the intermediate types.
