Interpretive Summary:

Technical Abstract: Grey leaf spot caused by Magnaporthe grisea is a disease of increasing importance in the United States and Japan where perennial rye grass is used in turf. Currently, disease resistant varieties are not available and fungicide treatment is required to control the disease. The disease occurs in a sporadic but catastrophic manner, destroying whole fairways with a few days when environmental conditions are condusive. In order to breed new varieties of turf grass with resistance to this disease, genetic studies of resistance were conducted in crosses of perennial rye and winter rye. The location of regions of the rye genome that contribute to disease resistance was defined. This is the first step toward development of disease resistant varieties of perennial rye.
