Dendrogram of 187 nonglutinous Korean rice varieties by UPGMA cluster analysis based on 10 SSRG loci. A total of 20 unique SSRG haplotype groups were identified within the 187 rice varieties. For each haplotype group, the number of rice varieties is shown in parentheses, except for haplotype groups with only one entry. Variety names are shown beside the corresponding haplotype group; Arabic numeral prefixes show their designated maturity groups (see Table 2). Note that the node in gray (0.456) split 187 nonglutinous Korean rice varieties into two subspecies— 170 Japonica varieties and 17 Tongil-type varieties, in which 15 (A–O) and 5 (P–T) SSRG haplotypes were identified, respectively.
