Abstract

The collection of 96 cultivars and promising lines of spring barley from Kazakhstan was studied for resistance to stem rust by using artificially infected field conditions of the Research Institute of problems for Biological Safety (Zhambul region). Obtained results of barley resistance at infected conditions were studied in relationship to grain yield recorded at 7 different locations of Kazakhstan during the period from 2009 to 2014. In addition, the results of 81 microsatellite markers screened for all 96 barley accessions were allowed to identify 9 DNA markers that statistically wise reliably associated with resistance to stem rust. A number of stem rust resistant lines for stem rust were identified for different regional barley breeding programs. The results of this work can be successfully used in studies associated with improved and efficient breeding for disease resistance and higher grain yield of barley in Kazakhstan.
