PVE, the percentage of variation explained;
Additive effect, positive additivity indicated that G-type Barbarea vulgaris carries the allele for an increase in the trait value, while negative additivity means that P-type plants carries the allele for an increase in the trait value;
MLL, maximum leaf length; MLW, maximum leaf width;
L, lightness; a*, redness and greenness and b*, yellowness and blueness;
NAS, 2-phenylethylglucosinolate (gluconasturtiin); BAR, (2S)-2-hydroxy-2-phenylethylglucosinolate (glucobarbarin); EBAR, (2R)-2-hydroxy-2-phenylethylglucosinolate (epiglucobarbarin); IM, 3-indolylmethylglucosinolate (glucobrassicin); 4mIM, 4-methoxy-3-indolylmethylglucosinolate (4-methoxyglucobrassicin)
