Marker–trait associations, chromosome location (Chr.), genetic positions (Pos., cM), number of surrounding markers (N), linkage disequilibrium (r2), and genetic distance (Dist., cM) pertaining to cases in which the log-likelihood ratio test of Jiang and Zeng (1995) rejected pleiotropy [H0: p(1)=p(2), P-value] in the population of 358 European winter plus 15 spring wheat varieties (GABI-WHEAT population)

aBivariate marker–trait associations as originally found by multiple-trait genome wide association mapping (MT-GWAS) in the GABI-WHEAT population (Fig. 1; Supplementary Tables S6, S8, S9).
bTraits involved in bivariate associations: grain yield (GY), thousand grain weight (TGW), grains per ear (GPE), and ear weight (EW).
cGenetic positions according to the reference map published by Wang et al. (2014).
dNumber of markers in the vicinity of markers with bivariate associations (r2>0.5).
eGenetic distance as well as r2 values were calculated between M1 and M2.
