Trophy -- A New Winter Oat Cultivar for Both Grain and Forage1

Ann Blount, Ronald Barnett, Stephen A. Harrison, and Cheryl Mackowiak2

Trophy is a new winter oat cultivar that was co-developed by Louisiana State University Agricultural Center (LSUAC) and University of Florida (UF). It is released under the SUNGRAINS consortium. Trophy has considerable potential for grain, forage, conservation tillage, and wildlife purposes in the Southern U.S. It has good straw strength and excellent crown rust and stem rust resistance. As with most eastern oat varieties, Trophy is susceptible to Barley Yellow Dwarf Virus (BYDV) infection. Delaying planting until cooler weather prevails tends to alleviate the spread of the virus since it is aphid vectored. When planted early fall for forage, Trophy is very disease resistant although BYDV infection may result in some stunting and leaf discoloration.

Grain Production

Trophy (experimental line LA9810) has excellent grain yield and high test weight. Trophy had a two-year mean yield (2004 and 2005) of 114.1 bu/acre in LA (5.0 bu/acre greater than the leading variety (Plot Spike LA9339) and 13.6 bu/acre greater than the test mean). It had the highest test weight of all entries of 35.9 lbs/bu (3.0 lbs/bu greater than the test mean). Trophy heads about 4 days later than Horizon 474 and 2 days earlier than Horizon 321.

Trophy was tested in the USDA Uniform Winter Oat Yield Nursery across the region from 2003 though 2005 and competed favorable with high yield, high test weight, low lodging and excellent disease resistance.

Forage Production

Trophy was tested for forage yield at several locations in the southeastern U.S. during 2005. It had an average forage yield of 6795 lbs/acre in Georgia (Tifton, Plains, and Griffin). This was slightly below the test average of 7202 lbs/acre and equal to that of Harrison (6991 lbs/acre). Trophy had a two-year mean forage yield of 7608 lbs/acre compared to a mean of 7894 lbs/acre for all entries in the trial.

The 2005 forage data for Louisiana state variety testing is available at: http://www.agctr.lsu.edu/NR/rdonlyres/88015E34-531D-46ED-BE85-83D731A82F1A/14864/RS167.pdf. Trophy had a mean forage yield of 6208 lbs/acre across two locations in Louisiana for 2005. The mean of 12 oat entries was 6232 lbs/acre.

Trophy oat is considered to be an excellent choice for grain, forage and wildlife use across the southern and U.S.
