Interpretive Summary: The Uniform Oat Winter Hardiness Nursery (UOWHN) is a cooperative effort of the USDA-ARS and various state Agricultural Experiment Stations to allow plant breeders to evaluate promising experimental cultivars for their ability to survive the winter in a wide variety of growing conditions. The 2002-03 UOWHN consisted of 19 entries including four check varieties. The 15 experimental lines were contributions from the United States and one foreign country. Eleven of these fifteen lines were new entries this year. The nursery was planted at each location as two replications of single-row, 5-foot plots. Seed for 13 tests was sent to six US states and seven foreign countries. All plants survived at three locations. The data from 3 locations were analyzed statistically. Winter survival for the lines, averaged over 3 locations, ranged from 51.7% to 70.8%. Location averages ranged from 11.4 % 98.7 %. Winter Turf (check) had the highest survival (70.8 %) in the test averaged over 3 locations. NC99-3802 had the highest survival (67.5%) in the test among the experimental lines when averaged over 3 locations. Based on these tests, all other experimental lines had overall averages, which differed from NC99-3802 by an amount too small to determine if the differences were due to environmental variation or genetic differences in winter hardiness.
