Summary

Varieties differ in their ability to produce a, dependable crop. In New York experience has shown Katahdin and Cobbler to be favorable in this respect, whereas Green Mountain has a reputation of being variable

Yield data over locations were analysed in all possible combinations of pairs of varieties. Estimates of the variety × location component of variance were obtained for each of these analyses. The average of these components for all combinations having a variety in common was defined to be the relative contribution by that variety to the variety × location interaction. In four of five analyses, Green Mountain had the highest relative contribution to the variety × location interaction, and Cobbler and Katahdin had a low contribution.
