Correlation coefficients (r) of mean relative area under the disease progress curve (rAUDPC) and infection type (IT) of the Druchamp × Michigan Amber-derived recombinant inbred lines tested in the eight environments.

a The field tests in Pullman (eastern Washington) and Mt. Vernon (western Washington) were conducted under natural infection of Puccinia striiformis f. sp. tritici. Greenhouse tests were conducted under high-temperature cycle (10–30°C); plants were inoculated at the adult growth stage of booting with races PST-25 and PST-127 that were virulent on seedlings of Druchamp; and all growth stages of Michigan Amber were susceptible to the two races.b The r values based on IT data are given in the parentheses. All of the r values were significant at P Correlation coefficients (r) of mean relative area under the disease progress curve (rAUDPC) and infection type (IT) of the Druchamp × Michigan Amber-derived recombinant inbred lines tested in the eight environments.
