Figure 1. Gel electrophoresis showing segregation pattern of the four SSR markers, (A) Xgwm429, (B) Xgwm319, (C) Xwmc477, and (D) Xstm773-2, in a subset of the F₂ progenies from a cross between near-isogenic lines (Sr36/9*LMPG and LMPG); P1, resistant parent; P2, susceptible parent; R, resistant F₂; S, susceptible F₂; H, heterozygous F₂ progenies. The arrow points indicate the size of the band associated with Sr36.
