Figure 4From: Population- and genome-specific patterns of linkage disequilibrium and SNP variation in spring and winter wheat (Triticum aestivum L.)Principal component analysis of genotyping data. A) Clustering of winter and spring wheat lines; B) Clustering of pre-defined breeding populations; sCA, sCM, sID, sWA, sWB, sMN, sMT and sSD - spring wheat populations; wMT, wNE, wSD, wKS, wNY, sCO, wOK, wTX and wWB - winter wheat populations.Back to article page
