  1. GDSSR: genetic distance calculated based on SSR marker; GDSNP: genetic distance calculated based on SNP marker. A, C, D, and E indicate the F1 population, respectively. PH, plant height; BW, boll weight; LP, lint percentage; BN, boll number; FL, fiber length; FS, fiber strength; MIC, micronaire; FU, fiber uniformity; FE, fiber elongation rate; SCI, spinning consistency index. *, ** Indicate significance at P < 0.05 and P < 0.01, respectively.
