- ... Using simple sequence repeat (SSR) and amplified fragment length polymorphism (AFLP) marker analyses, the genetic structure of selected South African wheat stem rust races was compared with Ug99. SSR analysis divided the population into two distinct groups with 24.5% similarity between them. A local race, UVPgt55 (North American race notation TTKSF), grouped with Ug99 (TTKSK) with a 100% similarit ...

- ... Continued genetic control of the cereal rusts depends on the availability of effective resistance genes. The wild relatives of wheat (Triticum aestivum L.) constitute a source of such genes. Wheat leaf rust (Puccinia triticina Eriks.) resistant Aegilops neglecta accession 155 was crossed with 'Chinese Spring'. Resistant progeny were initially backcrossed to Chinese Spring and later to Chinese Spri ...
