| Abstract/Contents: | "The development of perennial ryegrass resistant to gray leaf spot (Pyricularia grisea) may be an effective way to control this disease. However, previous disease trials failed to identify varieties with acceptable levels of resistance. To identify novel sources of resistance, we screened 200 USDA accessions representing worldwide sources using a conidial suspension. While field trials were unsuccessful in 1999 and 2000, greenhouse screening identified accesssions that covered the spectrum of resistance and susceptibility. Commercial field evaluations in Sept. 2000 identified several varieties with moderate resistance. Two mapping populations were developed separately from a two-parent tall fescue cross and a perennial ryegrass topcross. We are currently identifying patterns of inheritance and DNA markers associated with resistance from these crosses. Further genetic studies will map these genes, compare homologues with related host-pathogen systems, and create expressed sequence tags to use in germ plasm screening." |
