Fig. 1From: Genetic dissection of eating and cooking qualities in different subpopulations of cultivated rice (Oryza sativa L.) through association mappingPopulation structure and divergence of 253 rice cultivars. a The mean LnP(D) changed with the number of subgroups. b The ΔK value changed with the number of subgroups. c Neighbor-joining tree constructed from simple matching distance of all markers. Red, japonica; green, indica. d Comparison of allele frequencies between indica and japonica. For each marker, we identified the minor allele across all landraces and then calculated the frequency of this allele in indica and japonica. e PCA plots of the first two components of 253 rice cultivarsBack to article page
