    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.

    Inheritance of Fiji disease resistance
    (BSES, 1981) Hogarth, DM; Ryan, CC
    Various projects have been conducted in recent years to study the inheritance of resistance to Fiji disease. In this report the results of these studies are presented and the implications for the plant breeding programme discussed.

    Review of the R&D response to sugarcane smut with special reference to the SmutBuster Research Program : 16-20 February 2009
    (BSES, 2009) Hoy, J; McIntosh, B; Hogarth, DM
    The BSES-CSIRO sugarcane improvement joint venture was successful in obtaining the funding for work towards the development of productive, smut-resistant varieties in a project called SmutBuster. The SRDC-BSES research agreement for the SmutBuster project includes a requirement to review the breeding strategy for smut resistance. In January 2009, BSES commissioned Professor Jeff Hoy, Louisiana State University, Professor Bob McIntosh, University of Sydney, and Dr Mac Hogarth, formerly with BSES and SRDC, to conduct the review.

    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.

    Sugarcane smut yield-loss estimates - eastern Australia 2006 : Responses to questions raised by the consultative committee on emergency plant pests
    (BSES, 2006) Croft, BJ; Allsopp, PG; Egan, BT; Hogarth, DM
    This document has been prepared by BSES scientists with extensive experience with sugarcane smut. It is based on our reviews of published literature and first-hand experience with smut in the Ord River Irrigation area and Childers-Bundaberg regions of Australia.

    The inheritance of ash in juice from sugar cane
    (1983) Hogarth, DM; Kingston, G
    Ash per cent juice data were obtained for varieties within 97 crosses in original seedlings in 1979 and for varieties within 86 crosses from three factorial polycrosses in 1981, on the Bundaberg Sugar Experiment Station. The data showed that many crosses had higher ash levels than the standard variety Q87. In experiment I, Q87 had slightly lower ash levels than Q109 and Q111, and all three were significantly lower than Q110. It was found for experiments I and II, that 65 and 54 per cent respectively of the phenotypic variation was associated with genetic characters. As 95 per cent of genetic variation was additive, the prospects for breeding lower ash canes from low ash parents are very good. However, selections based on ash assessment may reject many varieties with other desirable agronomic characters. Negative correlations existed between ash per cent juice and Brix. However, the correlations were too low to assume that selection for high Brix canes would result in selections with lower ash levels.
