Fig. 2From: Association mapping for yield traits in Paeonia rockii based on SSR markers within transcription factors of comparative transcriptomePairwise LD (r2) between EST-SSRs. X and Y axis represent the 58 EST-SSRs. The different colors correspond to the thresholds of r2 and P. r2 < 0.1 and P < 0.001 represent linkage equilibrium, r2 > 0.1 and P < 0.001 represent LDBack to article page
