- Title
Evidence of allelism between genes <em>Pm8</em> and <em>Pm17</em> and chromosomal location of powdery mildew and leaf rust resistance genes in the common wheat cultivar 'Amigo'

- Abstract
TIBL- IRS wheat-rye translocation cultivars utilized in wheat programmes worldwide carry powdery mildew resistance gene Pm8. Cultivar `Amigo' possesses resistance gene Pm17 on its TIAL- IRS translocated chromosome. To be able to use Pm l7 efficiently in breeding programmes, this gene was transferred to a TI BL-IRS translocation in line Helami-105, and allelism between Pm8 and Pm17 was studied. The progenies of the hybrids in the F2 generation and F3 families provided evidence that the two genes are allelic. Genetic studies using monosomic analyses confirmed that in cultivar `Amigo', Pm17 and leaf rust resistance gene Lr24 are located on a translocated chromosome involving IA and IB, respectively.
