Transmission and genetic stability of non-homoeologous small fragment wheat–haynaldia villosa translocation chromosomes with Pm21 in various cultivar backgrounds of common wheat

Pm21 (a powdery mildew resistance gene) is from Haynaldia villosa (a diploid wheat related species). The researchers have developed two small fragment translocation lines with Pm21 (terminal translocation line NAU418 and the small interstitial transl...
