location as fixed effects with years as random effects. The significance level used
was a=0.05.
5.3 Results and Discussion
When the Bartlett test for homogeneity of the variance was conducted it
showed that 2005 and 2006 had variances that were not equal and should not be
analyzed together, therefore, 2005 and 2006 results are presented separately.
5.3.1 ANOVA for 2005 and 2006
From the 2005 analysis genotype, location, treatment, location x genotype,
and location x treatment effects were significant. The genotype x treatment
interaction was not significant in 2005 (Table 5.4).
Table 5.4 Main effects and F values for the preharvest treatment study in green
lentil grown at SPG and Goodale during 2005.
Effect df F Value
Genotype 14 7.21**
Treatment 1 152.42**
Location 1 43.33**
Location x genotype 14 4.96**
Location x treatment 1 25.85**
Genotype x treatment 14 1.68
** Denotes significance of greater than a=0.05
In 2006 all of the main effects and interactions were highly significant. This
was similar to 2005 except that the genotype x treatment interaction was also
significant (Figure 5.5). A significant genotype x treatment interaction is similar to
