Genetic similarity coefficient and cluster analysis of 200 maize accessions using SSR data. (a) Genetic similarity coefficient frequency distribution. The genetic similarity coefficient was calculated by SSRAnalyzer V1.0 (Software copyright registration number: 2018SR003610). (b) Cluster analysis of waxy lines. Cluster analysis based on allele identity was carried out using PowerMarker V3.25 with the neighbor-joining method. Different colors of taxon names represent different mutant alleles in waxy gene. Different colors of subtree markers represent different origin regions of waxy maize. Different colors of branch lines represent different waxy maize groups. wx-hAT: waxy maize with wx-hAT mutant allele; wx-D7: waxy maize with wx-D7 mutant allele; wx-D10: waxy maize with wx-D10 mutant allele; wx-124: waxy maize with wx-124 mutant allele; Other: waxy maize had other mutation in waxy gene, which was different from wx-hAT, wx-D7, wx-D10 and wx-124; Not analyzed: the sequence of these waxy maize lines were not obtained; Beijing, China: waxy maize originated from Beijing city in China; Jilin, China: waxy maize originated from Jilin province of China; Shanxi, China: waxy maize originated from Shanxi province of China; Korea: waxy maize originated from Korea; Group A: waxy maize classified into group A; Group B: waxy maize classified into group B; Group C: waxy maize classified into group C.
