A Latin square design is explained in which the cells are made up of groups of strains of tomatoes. A test for homogeneity was applied to the variances to determine whether or not certain sums of squares could be pooled to obtain an estimate of error. Applications were made showing how to test between means of strains within the same group and between means of strains in different groups. A method is presented for analyzing the entire Latin square after estimating yields for certain plots which appeared to be extraordinary.
