Powdery mildew resistance of Amigo wheat has been analyzed and mapped by combining F 2 segregation data with cytogenetic and storage protein analyses. It is concluded that the powdery mildew resistance of Amigo is regulated by one gene with conditioned dominance. Cytogenetic and electrophoretic analyses revealed that the complete wheat chromosome arm 1AS is missing in Amigo and has been replaced by the rye chromosome arm 1RS. No susceptible recombinant was found among 1,034 F 2 plants of crosses of Amigo with Pm3 resistant lines; Pm3 is known to be located on 1AS (...)
