SSW, single seed weight; NP, number of pods per plant; NOP, number of ovules per pod; RSS, rate of seed-set; SY, seed yield per plant.

Data were obtained from 12 plants (3 plants with 4 replications) for each genotype.

The flanking marker of qSw13-1 is indicated in boldface type.

N and T indicate the ‘Natto-shoryu’ and ‘Tachinagaha’ alleles at each marker locus, respectively.

Trait value of each genotype group is shown as mean ± standard deviation.

^{** and ***}represent statistical significance at P < 0.01 and 0.001 by Welch’s t-test, respectively; NS = not significant.
