摘　　要：近年来,糯玉米(ZeamaysL.var.certainaKulesh)因其独特的口感而广受欢迎,成为备受人们喜爱的农产品。然而,在糯玉米自交系方面,目前并没有明确的类群划分。为了提高东北地区鲜食糯玉米育种的效率,利用Maize6H-60K基因芯片对来自东北地区的96份糯玉米自交系进行基因型分析。结果表明,在96份自交系中,14312个SNP标记检测到基因多样性为0.098~0.500,平均值0.387;最小等位基因频率(MAF)为0~0.5,平均值0.380;多态性信息量(PIC)为0.094~0.375,平均值0.306。96份材料最终划分为3个类群,A类群为垦粘1母本血缘群,B类群为先糯父本血缘群,C类群为垦粘1父本血缘群。In recent years,waxy maize has been popular due to its unique texture and has become a favoured agricultural product widespread popularity.However,for waxy maize inbred lines,currently no clear classification has been reported.In order to improve the efficiency of fresh glutinous corn breeding in the Northeast of China,this study utilized the Maize 6H-60K gene chip to conduct genotype analysis on 96 waxy corn inbred lines from the Northeast of China.The results showed that among the 96 inbred lines,the gene diversity detected by 14312 SNP markers ranged from 0.098 to 0.500,with an average of 0.387.The minimum allele frequency ranged from 0 to 0.5,with an average of 0.380,and the polymorphic information content ranged from 0.094 to 0.375,with an average of 0.306.The 96 materials were ultimately classified into three clusters,group A was the Kennian 1 maternal group,group B was the Xiannuo paternal group,and group C was the Kennian 1 paternal group.
