Fig. 1From: Association mapping for yield traits in Paeonia rockii based on SSR markers within transcription factors of comparative transcriptomeEstimation of genetic structure of 420 accessions for P. rockii population using 58 EST-SSRs based on the STRUCTURE. a. Log probability data [LnP (D)] for each K value (10 replicates); b. ΔK estimates of the posterior probability distribution of the data for a given K; c. Estimated population structure and clustering of the 420 P. rockii individuals with K = 2 to 6. Individuals are shown by thin vertical lines, which are divided into four major well-separated genetic clusters (I, II, III and IV) standing for the estimated membership probabilities of each individualBack to article page
