Abstract:
... Wheat stem rust (WSR), caused by Puccinia graminis subsp. graminis Pers., is a highly destructive disease of wheat and several other small grains. The discovery of P. graminis subsp. graminis race Ug99, which overcomes previously effective resistance in wheat, raises concerns for global wheat production and food security. There is currently no mathematical model that describes the duration of the ...
