Analysis of linked leaf and stem rust resistance genes in wheat-rye recombinant ‘Selection 212’

Correlated behaviour analysis of F₃ and BC₁F₂ families of crosses involving ‘Selection 212’, a rust resistant stock developed through exploitation of homoeologous recombination between wheat and rye chromosomes, demonstrated that a common recessive gene effective to leaf rust pathotypes 77-1, 77-3, 77-4 and 77-5 individually and a recessive gene conferring resistance to stem rust pathotype 40A in Sel. 212 are closely linked.
