Abstract excerpt

Leaf stripe, caused by Pyrenophora graminea, is an important disease on highland barley in Qinghai Province, China. The pathogenicity and genetic diversity of P. graminea from six regions of Qinghai Province were examined. A total of 329 strains were collected, of which 230 were identified as P. graminea based on morphological characteristics and rDNA-ITS sequencing. The colony growth rate of P. graminea was...
