zGL: grain length, GT: grain thickness, RLW: ratio of length to width.

yChromosome number, xLogarithm of the odds score, wPhenotypic variation explained by the QTL.

vAdditive effect, add=(P1-P2)/2, the positive value of the additive effect indicates that the allele from Chamdongjin (P1) contributes to an increase in the trait value.
