The determination of winter-hardiness in oats

Abstract

When assessing the value of any variety of a commercial plant one is concerned with a number of different features of the plant's behaviour, among others winter-hardiness. The behaviour with regard to most of these features is tested by methods which have been carefully planned and whose reliability has been proved, but the determination of winter-hardiness is still a matter of observing the reaction of the plants to the conditions prevailing at that season of the year. However, in England, particularly in the southern counties, the winters are comparatively mild and it is only occasionally that the climate provides a really good test of the plant's resistance. On the other hand it is necessary to have some knowledge of the winter-hardiness of a variety, since otherwise disastrous results may follow on a really hard winter. A method of determining the resistance of new varieties in the laboratory would provide the solution to this problem.

Development of a Standard Artificial Freezing Technique for Evaluating Cold Resistance of Oats1

“…High correlations between .survival of wheats in artificial freezing tests and survival under field conditions have been reported by Martin ( 6), Quisenberry ( 10), Wiebe I and Quisenberry ( 12), and others. Mather and Anderson ( 7) concluded that artificial freezing tests of oat varieties in England and Sweden pro• vided a real test of the winterhardiness of the varieties. Murphy et al (9) employed artificial refrigeration in the selection of winter-hardy and disease resistant oat lines.…”
