Experiment fII:_ Bow_gpecins and Seedins
Rate Study
ANOYA were used to determíne the significance <strong>of</strong>
differences between genotypes, seeding rates, row spacings
and interactions <strong>of</strong> these for each <strong>of</strong> the seven parameters
measured. Single degree <strong>of</strong> freedom comparisons were used
to elucidate differences between the factor levels when
ANOVA indicated these to be significant "
Plan"b Heieht
Genotypíe hei.ght differences were significant at all
sites (Tab1e 54), as expected based on the choice <strong>of</strong> lines.
Seeding rate effects were not significant, but :.ow_spacings
effects were at irvo <strong>of</strong> the three locations (faUfe 5&).
