Inhoud: For testing of winter hardiness and to obtain estimates of heritability (h2) for this character, field experiments are the most common method. In order to develop a supplement to the field method, artificial freezing to test for freezing hardiness in the laboratory has been carried out. The purpose of the present study was to compare estimates of broad sense heritability (h2b) for winter hardiness in white clover (Trifolium repens L.) based on an experiment in the field, and freezing hardiness based on a laboratory test. The plant material consisted of six local populations with origins between ca. 61°- and 70° northern Latitude. The northern related populations Nos. 06 and 22 showed the best winter hardiness in the field, while the more southern related population No. 38 showed the best freezing hardiness in the laboratory. The field data was generally more variable than the laboratory data. In the field, h2b
