Abstract: The paper aim to understand the genetic diversity and evolutionary status of 21 varieties of red beet.Genetic diversity of 21 red beets was studied by InDel and SSR markers.The results showed that the molecular markers of InDel had 25 gene loci, 24 of which were polymorphic. The Shannon''s information index average was 0.583, the Nei''s gene diversity index average was 0.370, the allele K was 2~4, and the average was 2.4. The average observed heterozygosity was 0.235, the expected heterozygosity was 0.398, and the PIC of polymorphic information content was 0.330.The average values of Shannon''s information index were 0.926, the average values of Nei''s gene diversity index were 0.548, the average values of alleles K were 2~7, with an average of 4.625. The average observed heterozygosity was 0.399, the expected heterozygosity was 0.587, and the PIC value of polymorphic information content was 0.523.In this study, it was found that most red beets were closely related to each other. Therefore, when selecting new varieties, it is suggested to select the varieties with longer genetic distance as parents.
