基于SNP芯片对96份糯玉米自交系遗传多样性分析
Genetic Diversity Analysis of 96 Waxy Maize Inbred Lines Based on SNP Chip
摘要
Abstract
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 14 312 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.关键词
