Abstract:

China is the birthplace of foxtail millet, four traditional foxtail millet accessions of Qinzhouhuang, Taohuami, Longshanxiaomi, and Jingumi because of its good quality characteristics, has been selected as the royal tribute and is loved by people in Chinese history. To explore the genetic diversity of four Chinese famous foxtail millet and the genetic relationships among the namesakes, SSR and SRAP markers were used to analyze the genetic difference of 179 foxtail millet varieties. Results based on SSR markers showed that the genetic distance ranged from 0.0435 to 0.6304 with an average of 0.3267, the PIC was 0.2406, the allele frequency was 0.7845, and the genetic diversity was 0.2968. Based on UPGMA, 179 materials were clustered into 10 groups, and the clusters had certain correlation with their sources. The materials were divided into three groups based on structure and three groups based on principal component analysis. SRAP marker analysis revealed that the genetic distance ranged from 0.1818 to 0.9545 with an average of 0.6001, and the PIC, the allele frequency, and the genetic diversity were 0.5257, 0.5718, and 0.5688, respectively. Based on UPGMA, 179 materials were clustered into 14 groups. The materials were divided into three groups based on structure and principal component analysis. The groups were clearly divided and the origin of the groups was consistent with their source.

Key words: Chinese traditional foxtail millet accessions, Qinzhouhuang, Taohuami, SSR, SRAP, genetic diversity
