Polymorphism in the short arm of 1R rye chromosomes in wheat lines with 1RS.1BL translocation and 1R(1B) substitution from different sources

Abstract

Aim. The short arm of 1R rye (Secale cereale L.) chromosome is widely used in the breeding of bread wheat (Triticum aestivum L.), in particular 1RS.1BL, to introsgress genes of resistance to leaf (Lr26), stem (Sr31), striped (Yr9) rusts, as well as powdery mildew (Pm8); 1RS.1AL carries Gb2/Gb6 resistance genes to the wheat aphid (Schizaphis graminum Rondani), powdery mildew (Pm17), and the Cmc4 resistance gene to the Aceria tosichella Koifer mite, which is a vector for spreading of wheat mosaic virus. The aim of the research is to reveal molecular genetic polymorphisms of short arm rye 1RS chromosomes of different origins in bread wheat lines with 1RS.1BL translocation or 1R(1B) substitution from different sources. Methods. Genetic polymorphism of lines was analyzed by using PCR with a number of rye and wheat microsatellite markers. Results. It was shown that the CWXs line has a recombinant 1RS arm that contains the chromosomes parts of 1RS of the parental lines H242/97-2 and H273/97, due to crossover event, which led to the recombination of marked loci. Conclusions. Molecular genetic polymorphism has been reviled in 1RS.1BL translocations and 1R substituted rye chromosomes of different origins in H242/97-2, CWXs, H273/97, PavonMA1, Salmon lines, as there are different alleles present at loci: Xscm9, Xtsm422, Xgwm752, Xgwm18, Taglgap.
