These markers were found to be associated with the corresponding traits when four models were used: 1, the naive model-without controlling for Q and K; 2, GLM used after controlling the population structure (Q); 3, MLM used after controlling the population structure (Q+K); and 4, MLM used without controlling for the population structure (K). When detected using various models, the P-values were obtained using model 2 or 3, which controlled for the population structure. The model information was the same as for Tables 5, 6, and Supplementary Materials 7, 9, 11.
