Evaluation of Winter Hardness in Field Grown Winter Wheat

This experiment for evaluation method of winter hardiness, relationship among the winter hardiness related traits and their relations with heading time in wheat were carried out. The mean squares estimated among cultivar and heritabilities estimated were higher at 20cm high ridges than the 10cm high ridges. The rate of winter killed plant remarkably noticed and easier to identify the varietal differences at 20cm high ridges, The correlation coefficients estimated between winter hardiness related traits was highly positive, significance especially between winter killed tillers and plants were 0.8627**, -0.8238** at Suweon and Yeoncheon. Also, Correlation coefficients estimated among the heading time and winter killed leaves, tillers and plants were -0.2283**, -0.2820** and -0.3050, respectively. High ridge top seeded method for evaluation of winter hardiness were effective to distinguish its varietal differences and found to be the methods that can screen number of varieties and segregating materials.
