Using 5 pairs of specific SSR primers to analyze the genetic diversity of 40 broomcorn millet germplasm resources. The results showed that a total of 13 allelic variations were detected, the allele number of each pair primer and each SSR locus was 2~3 and 2.6 separately. The Shannon index ranged from 0.67 to 1.08,with an average of 0.88. The polymorphism information index ranged from 0.46 to 0.67, with an average of 0.58.Cluster analysis was conducted and the 40 materials were classified into 6 groups at th...
