  • Patent number: PP4380
    Abstract: A Kentucky bluegrass plant that is highly apomictic, thus providing a more uniform turf when propagated from seeds. The plant has good resistance to most diseases such as stripe smut, Helminthosporium leafspot, dollarspot, and rust. The production of a high number of rhizomes presents a dense turf which keeps weed competition down. This low-growing cultivar has a medium-textured turf and maintains its medium-green color for a longer season than some other varieties of bluegrass. The new variety of Kentucky bluegrass plant was selected from a large number of other bluegrass plants released in 1969 by Rutgers University to FFR Cooperative for variety development. The new variety was the result of replicated tests in cultivated areas at West Lafayette, Indiana and Spokane, Washington as reported hereinafter and the variety subsequently has been named "Plush".
