MetadataShow full item record
The impact of GxE interaction on the response to three methods of selection was assessed over three locations and three crop-years. The three selection methods considered were two previously used procedures, mass (individual) selection using a visual appraisal of clonal performance and family selection using selection rate, and a new procedure, family selection using a grade based on weighed family plots. Within the two forms of family selection, light mass selection based on a visual appraisal of clonal performance was used to reject the poorest clones. The gains from selection, calculated as the deviation in performance of the select groups from the performance of a group of randomly chosen clones, were assessed for each of these three methods.
