P values are for comparison between phenotypic values of favorable allele and others.

*, **, *** indicate significance at P = 0.05, 0.01 and 0.001, respectively. Underlined values indicate that lines with the single favorable WSC allele produced significantly (P < 0.05) higher TGW at maturity than accessions with other alleles.
