An important precondition for the reliable production of winter oats is for the varieties to have satisfactory winter hardiness. Oats have the poorest frost resistance of all the winter cereal species, so special attention must be paid to this trait. A phytotron testing method has been elaborated to test the frost resistance of winter oat varieties and lines, and the hard winter of 2002/2003 also allowed winter hardiness to be tested under natural conditions. The genotypes included in the experiment exhibited substantial differences in frost resistance and winter hardiness. The differences in frost resistance determined in the phytotron were reflected in the winter hardiness values recorded in 2002/2003. At both locations, two lines bred in Martonvá sár and two foreign varieties proved to have above-average winter hardiness. The grain yield was low in 2003, partly because of the high proportion of frost kill, and partly because the weather in the growing season was the driest experienced over the last decade. Even plant stands which over-wintered well were unable to produce good grain yields, because there was no rainfall during the most critical period, from shooting to heading, as in other parts of the country. The yield level was determined to the greatest extent by the overwintering value of the genotypes. Winter oats have not become a common crop in Hungary despite the fact that attempts at cultivating this species have been made for a long time. The present results indicated that there are significant differences between oat varieties as regards both frost resistance and overwintering. Oat varieties originating from America proved to have better winter hardiness than those bred in the UK, Germany or France. Comparative trials in Martonvásár on 36 winter oat genotypes and the same number of spring genotypes indicated that in four out of five years, when there was no frost damage, winter oats gave a higher yield than spring oats.
