Breeding perennial ryegrass for resistance to gray leaf spot.(Turfgrass Science)

From: Crop Science | Date: March 1, 2004| Author: | Copyright information

Gray leaf spot, caused by the fungus Pyricularia grisea (Cooke) Sacc. [teleomorph Maguaporthe grisea (T.T. Herbert) Yaegashi & Udagawa], can be a devastating disease on perennial ryegrass (Lolium perenue L.). The identification and utilization of perennial ryegrass cultivars with improved resistance to gray leaf spot would reduce the need for fungicide applications. The objectives of this study were to: (i) evaluate cultivars, experimental selections, and single-plot progenies of perennial ryegrass for resistance to gray leaf spot, (it) develop populations from selected resistant parents to ...
