摘　　要：为筛选耐盐玉米自交系,为玉米耐盐品种的选育提供基础,通过盐胁迫下玉米自交系发芽试验,从200份玉米自交系中初步筛选获得一份耐盐自交系NY71。又通过盐胁迫下幼苗生长量、含水量、叶片盐害指数、叶绿素含量以及渗透物质含量的测定试验,最终确定自交系NY71为耐盐玉米自交系。In order to select salt tolerance maize inbred lines for the salt tolerance maize variety breeding,200 maize inbred lines germination rate was detected under salt stress.A maize inbred lines NY71 germination rate was the highest.NY71 was identified as a salt tolerance maize line by the determination of maize seeding dry weight,water content,salt stress index,chlorophyll content and osmotic adjustment substance content.

关 键 词：玉米自交系 耐盐性 盐害指数
