Factors affecting the sugar content of sugar cane in the wet tropics of Queensland: statistical analysis of ccs data at Babinda and Tully
(BSES, 1972) Sturgess, OW; Hogarth, DM; Hurney, AP; Leverington, KC
In the wet tropics, the sugar content of crops is usually below the state's average and is a critical factor in farm economy, particularly during years of low sugar prices. This aspect of sugar production has been the subject of detailed investigation.

Selection of superior crosses of sugarcane : SRDC final report BS6S
(1991) Bull, JK; Hogarth, DM
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.
