  ABSTRACT: To confirm allelic relationship between Lr9 and the leaf rust resistance gene in KLM4-3B, genetics of resistance was studied using crosses (WL711 + Lr9) × WL711 and (WL711 + LrKLM4-3B) × WL711. The F2 populations in cross (WL711 + Lr9) × WL711 and (WL711 + LrKLM4-3B) × WL711 segregated in ratio of 3:1 for disease reaction at seedling stage against pathotype 77-5 of leaf rust. This suggests that rust resistance in these stocks are under the control of single dominant genes. Further, to study allelic relationship betweenLr 9 and LrKLM4-3B, F2 population of the cross (WL711 + LrKLM4-3B) × (WL711 + Lr9) was studied. A segregation ratio of 15:1 implies that the two genes Lr9 and LrKLM4-3B are non-allelic genes.
