Statistical determination of barley varietal adaptation
1934
Immer, F.R. | Hayes, H.K. | Powers, L.
1. The analysis of variance was applied to a variety test with barley. 2. The method for calculating the variance of the different components of the total variation was illustrated. 3. The interactions of varieties X stations, varieties X years, and varieties X stations X years were significantly larger than error, indicating that some varieties reacted differently in different stations, in different years, and in certain stations in specific years. 4. The variety mean square significantly exceeded the mean squares for interaction of varieties X stations and varieties X years, showing that some varieties were significantly superior to others in spite of the differential responses.
