Abstract

Twin-sets and a few triplet-sets from ‘Belturf,’ ‘Fylking,’ and ‘Cougar’ Kentucky bluegrass (Poa pratensis L.) were inoculated with Drechslera triseptata (Drechs.) Subram. Jain, Erysiphe graminis DC. ex Merat, or both. Plants were identified that differed from their parent cultivar in reaction to each pathogen. When inoculated with D. triseptata, 10 plants from 32 Belturf sets were more resistant than the cultivar. In 27 Fylking sets, 2 plants were more resistant and 12 more susceptible than the cultivar. When inoculated with E. graminis, 8 plants in 34 Belturf sets were more resistant than the cultivar. In 30 Fylking sets, 1 plant was more resistant and 4 more susceptible than the cultivar. In 26 Cougar sets, 4 plants were more susceptible than the cultivar. Populations of polyembryonic seedlings appear to be valuable sources of disease resistance in Kentucky bluegrass.
