Avena macrostachya is a perennial, autotetraploid oat. In its natural habitat it has a high degree of winter hardiness. The objective of this experiment was to screen 53 backcross progenies of an interspecific cross between the cultivar Brooks (A. sativa) and A. macrostachya using a controlled freezing test. No entry tested was more freezing tolerant than the recurrent parent Brooks. These results indicated that freeze tolerance from A. macrostachya had not been introgressed into the progeny. It was suggested that the mechanism for winter hardiness in A. macrostachya is different from that in A. sativa and may involve an escape mechanism rather than a genetically controlled freezing resistance mechanism.
