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.
