Wheat crops face threat of new yellow rust race
The National Institute of Agricultural Botany is investigating a potential new race of yellow rust on winter wheat.
In 2008 the United Kingdom Cereal Pathogen Virulence Survey (UKCPVS) collected two isolates of yellow rust from Group 1 wheat Solstice and confirmed that they were virulent on seedlings of the variety. Solstice currently has a resistance rating of 9 and, until last season, was resistant to all known races of yellow rust.
