[Abstract]
In 2012 — 2014, the resistance of wheat stripe rust races and mixed bacterial inoculation of 1 226 wheat varieties (lines) from 23 breeding and related units is identified at the seedling stage and the adult stage. The result indicates that the material of disease resistance is 374 samples, which covers 30.51% of total number of identification materials of the current epidemic of wheat stripe rust physiological rust at the adult stage. The material of disease resistance is 87 samples, accounting for 7.10% of total number of identification material at the whole growth period. A number of wheat resistant materials for breeding and production have been selected.
