The genetic control of virulence was studied in four isolates of the fungus Pyrenophora teres f. teres, originating from various geographic regions in experiments with nine barley accessions, possessing known resistance genes. Experiments were performed with the ascospore progeny of two crosses. The results of segregation for virulence in the progeny of direct crosses were confirmed by analysis of backcrosses and sib crosses. One to four genes for avirulence toward various barley genotypes were found in the isolates under study. It is suggested that dominant suppressor genes are involved in the genetic control of avirulence toward four barley genotypes.
对来自不同地理区域的四种真菌网斑病菌圆斑专化型分离株的毒力遗传控制进行了研究，实验中使用了九个具有已知抗性基因的大麦种质。对两个杂交组合的子囊孢子后代进行了实验。通过回交和姊妹交分析证实了直接杂交后代中毒力分离的结果。在所研究的分离株中发现了一至四个针对不同大麦基因型的无毒力基因。研究表明，显性抑制基因参与了对四种大麦基因型无毒力的遗传控制。
