Validation of molecular markers for wheat breeding

Abstract
Five sets of markers were assessed for their usefulness in breeding, two linked to wheat stem rust gene Sr2, several markers linked to a chromosome segment conferring Yr17/Lr37/Sr38 resistance, two reported markers for the linked genes Lr35 andSr39, one for Lr28, and one linked to flour colour. The gene for Sr2 confers adult plant resistance to stem rust (Puccinia graminis f.sp. tritici) and was originally transferred to bread wheat from the tetraploid emmer (‘Yaroslav’) to the cultivars Hope and H-44. The gene is located on the short arm of chromosome 3B and confers a durable adult plant resistance to stem rust usually expressed only in the field. The chromosome segment carrying the Lr37, Sr38, Yr17 resistance genes is located on 2AS and was originally introduced into wheat through an Aegilops ventricosa Triticum persicum cross, followed by a cross to the cultivar Marne (VPM1). The flour colour quantitative trait locus was originally described in a Yarralinka Schomburg cross and is located on chromosome 7A. The primers as originally developed required optimisation for more routine use in a breeding program.
