Narrative
Highest or not different from the highest forage yielding entries in almost all the ryegrass trials during the three seasons, 1997-98, 1998-99, and 1999-00 in Florida and other southeastern states. Later maturing and higher resistance to crown rust and gray leaf spot (Pyricularia grisea) than original Surrey diploid population. The crown rust index at Gainesville for year 2000 was 1.55, the highest crown rust resistance of all ryegrass genotypes studied. Also had high seed yields and resistance to stem rust (P. graminis) typically found in ryegrass seed production areas of the Willamette Valley, Oregon. Moderate resistance to Helminthosporium leaf spot disease (Dreschlera spp.) and was considerably more resistant than Surrey. Cold resistance may have increased from doubling the chromosomes as was disease resistance and maturity. Larger plant including stems, leaves, seed heads and seed than the diploid, Surrey. Protein content and IVOMD compares favorably with Surrey and other ryegrass cultivars. Because of its large size, expected to be primarily used for forage purposes. Later maturing and grows later into spring than Surrey.
