Ten varieties and a mixture of alfalfa were grown at 60°, 70°, and 80° F. at 8-, 12-, and 16-hour daylengths for each temperature. Growth responses measured in cm. showed the greatest height differences at 60° F. and 12-hour daylength. At this temperature, the varieties and mixtures could be divided into three groups according to the magnitude of the variances. Varieties within each group were significantly different in height from varieties in other groups.
