    Whole-farm planning for management of varieties to maximise productivity and reduce losses from diseases : SRDC final report BSS294
    (2009) Croft, BJ; Cox, MC; Millard, D; Burrows, A
    The appropriate selection of sugarcane varieties is critical for maximising profitability and sustainability for both growers and millers in the Australian sugarcane industry. Growers are faced with many complex decisions when selecting varieties such as yield potential, suitability to soil type, optimum mix of varieties to maximize sugar content throughout the season, resistance to diseases and pests, ratooning ability and tolerance to stresses such as drought, frost and flooding. This project has developed a web-based variety decision support tool and information resource for the Australian sugarcane industry named QCANESelect to help growers make the best variety choices.

    Estimates of breeding value of sugarcane clones and their impact on efficient parent management and cross pollination : SRDC final report STU060
    (2010) Atkin, F
    Sugarcane breeders in Australia use family trials from four regional programs to estimate breeding values of current parents. Genetic gain to the Australian sugarcane industry can be maximised through efficient parent selection and choosing specific family combinations for cross pollination. This project has resulted in a new system of estimating the breeding potential of sugarcane parents in the BSES CSIRO breeding program. More accurate assessment and selection of sugarcane parents for cross pollination is likely to result in increased genetic gain through managing parent populations more efficiently, selecting better cross combinations, and advancement of superior varieties into later stages of selection. The project has formed the basis of a PhD thesis submitted to the University of Queensland.

    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.
