Slope-b slopes of regression of variety means on site index values
*Indicates slope significantly different from the slope for the overall regression which is 1.00.
MS-TXL contribution of each variety to interaction.
MS-REG contribution of each variety to the regression component of the treatment by location interaction.
MS-DEV Deviations from regression component interaction.
R2 Squared correlation between residual from the main effects .model and its site index.
