Fig. 4. SSR band polymorphisms of a F₂ population derived from a cross between a tawny pubescence cultivar Karafuto-1 (TT) and a gray pubescence cultivar Toyosuzu (tt) using the SSR primer SoyF3'H. Genotypes at the T locus were determined by testing 15 progeny of each F₃ families. M, molecular size marker; 1, Karafuto-1; 2, Toyosuzu; T, F₂ plants with TT genotype; H, F₂ plants with Tt genotype; t, F₂ plants with tt genotype. The SSR bands cosegregated with the genotype at the T locus. The migration of size markers is shown to the right of the gel.
