Phenotypic characterization of the seeds of Yuzhi 4 and BS lines.
(A) Seed size and shape phenotypes of Yuzhi 4 and BS lines; scale bar: 0.5 cm. (B) Comparison of the SL, SW, and L/W ratio of Yuzhi 4 and BS lines. The data are presented as the mean ± standard deviation (SD) (n = 3). The asterisks indicate significant differences (t-test; *P < 0.05; **P < 0.01; ***P < 0.001) between Yuzhi 4 and BS.

QTLs for traits related to seed size and shape detected in BC1 population.
The black bar on each LG column indicates a marker. The QTLs for SL, SW, and L/W are shown in red, blue, and black, respectively.

QTLs for traits related to seed size and shape detected in F2 and BC1 populations.
The black bar on each LG column indicates a marker. The QTLs for F2 and BC1 populations are shown in black and red, respectively.
