In a study of heat resistance of potato varieties, six plantlets of four varieties of potatoes were randomly assigned to each of four temperature regimes. Weights of tubers were recorded after 45 days. The resulting experiment is a 4 3 4 factorial. The data are shown in Table 9.30. Perform the analysis to determine the nature of differences in heat resistance among the varieties. Make recommendations indicated by the results.
