Abstract:

The article reviewed the research advances of Ug99 and its resistance breeding, from the aspects of its discovery, race variation, pathogenicity, distribution, spread, exploration of relative resistant genes, linked marker screening, resistance breeding strategies and the research status of Ug99 in our country. It’s concluded that the Puccinia Graminis new race Ug99 and its rapid evolvement, broad and high virulence and rapid spread towards important wheat growing areas, now potentially threatens global wheat production. Exploiting novel genes of Ug99 resistance from wild relatives of wheat and developing new varieties with durable resistance should be emphasized for the protection of wheat production.
