Summary of stripe rust infection type (IT) and relative disease severity (rDS, %) data of the winter wheat panel (465 entries) in the tests with seven races of Puccinia striiformis f. sp. tritici at the seedling stage under the controlled greenhouse conditions and at the adult-plant stages under natural infection of the pathogen in various year-location environments and broad-sense heritability (H 2) in the field tests.

Stdev, standard deviation; CV, coefficient of variation; NA, not applicable as the test did not have repeats.
The environment consists of the year and location: 18-21, the years of 2018–2021; MV, Mount Vernon, Washington; PCFS, Palouse Conservation Field Station; and SP, Spillman Farm near Pullman, Washington; BLUE, best linear unbiased estimator.
