Amplification results of SSR primers of some parents and F₁ individual plants. a: Amplification of SSR specific primer H57 in the paternal inducible line (as paternal parent), 0933A (as maternal parent) and induced progeny, 0933A × Y3560 progeny, from left to right are M31–1, M31–2, M31–5, M31–7, M31–8, M31–12; 0933A × Y3380 progeny, from left to right are M30–1, M30–2, M30–3, M30–6, M30–10, M30–11. b: Amplification of specific SSR primer H38 in parents and hybrid progeny (0933A × ZS11). c: Amplification of SSR specific primer H57 in the paternal inducible line (as paternal parent), L0933A (as maternal parent) and induced progeny, L0933A × Y3560 progeny,from left to right are M35–1, M35–7, M35–9, M35–10, M35–12, M35–14; L0933A × Y3380 progeny, from left to right are M34–1, M34–2, M34–3, M34–5, M34–6, M34–9. d: Amplification of specific SSR primer H38 in parents and hybrid progeny (L0933A × ZS11). The samples derive from the same experiment and the full-length original gel is included in Additional file 5
