Haplotype analysis of the SSRs surrounding rym 11 locus in a set of winter barley

摘要

Haplotype analysis of the SSRs surrounding rym 11 locus in a set of winter barleyBreeding for Barley Mosaic Virus resistance is of great importance because of yield losses and the impossibility of plant protection using chemicals. Successful breeding of long-term resistant varieties requires widening of the genetic base of resistance, preferably by pyramiding of resistance genes. One of the perspective resistance genes is rym 11, resistant to all strains of Barley Mosaic Virus complex, but which is known to be present only in the cultivar Russia 57. In this work, the identification of potential new rym 11 resistance donors on the basis of haplotype analysis of the SSRs surrounding rym 11 locus is presented.
