Geographical distribution of study sites at locations in agroecological zones and provinces used to assess grain quality and ethanol production assessment from 2006 to 2009.

 


Fig. 2.

Biplot of agronomic, grain quality, and ethanol responses (vectors) relative to cultivars (points) generated with multidimensional preference analysis (generalized form of principal components analysis) for data collected at locations across Canada from 2006 to 2009. The percentage of variance explained by the first two principal components (x axis = first component and y axis = second component) is indicated on the respective axes.

 


Fig. 3.

Biplot (mean on y axis vs. CV on x axis) summarized across and by zone or province for yield (Mg ha–1), protein concentration (g kg–1), and starch dry weight concentration (g kg–1) data in six agroecological zones and provinces collected at locations across Canada from 2006 to 2009. In addition to cultivar estimates, estimates are also provided for the Canada western soft white spring (CWSWS) and Canada prairie spring red (CPS Red) wheat classes and indicated with different symbols. Grouping categories: Group I—high mean, low variability; Group II—high mean, high variability; Group III—low mean, high variability; Group IV—low mean, low variability.

Biplot (mean on y axis vs. CV on x axis) summarized across and by agroecological zone for ethanol concentration (L Mg–1) and yield (L ha–1) in six agroecological zones and provinces collected at locations across Canada from 2006 to 2009. In addition to cultivar estimates, estimates are also provided for the Canada western soft white spring (CWSWS) and Canada prairie spring red (CPS Red) wheat classes and indicated with different symbols. Grouping categories: Group I—high mean, low variability; Group II—high mean, high variability; Group III—low mean, high variability; Group IV—low mean, low variability.
