*Parent- contributing desirable allele. For the additive effect, a positive value means that the desirable allele is from the recipient parent (WTR-1), while a negative value means that the desirable allele is from the donor parent (Y-134). Abbreviations: Chr, chromosome; LOD, logarithm of the odds; 1st GC, 1st germination count; 2nd GC, 2nd germination count; GP-1, germination percentage; TFGS, total fresh weight of germinated seeds; TDGS, total dry weight of germinated seeds; and VI-1, vigor index
