• 1. Variations among plants of the same variety in fertility, plant height and heading date were observed on different generations of five tetraploid varieties. In general, tetraploid plants showed a wider range of variation than diploid plants.2. Having compared the variation among lines with that within lines (a line means plants raised from the seed of a plant of the preceding generation) by the analysis of variance, the variation among lines was in a greater part of cases found to be significant. In addition to this, significant correlations were found in some case between progeny and parent. Individual variation within a tetraploid variety seems, therefore, to be at least partly heritable.3. However, on account of the variation arising continually in every generation, selection seemed ineffective, and the average of measurements for a number of plants was recognized to be a character peculiar to the given variety. Fertility seemed not to be improved with the lapse of generations.
