    Improving the Plant breeding selection system for Fiji Disease Resistance : SRDC final report BSS255
    (2005) Croft, BJ; Ridley, AW; Dhileepan, K; James, AP
    Fiji leaf gall (FLG) has caused major epidemics in the Australian sugar industry in the past. All new cultivars of sugarcane released in areas affected by FLG should be resistant to the disease. New cultivars have been tested for resistance in field trials in the past but the field trials are unreliable with only a third of trials in the last 28 years giving reliable ratings. The aim of this project was to develop a method of rating clones for resistance to FLG that would be accurate, reliable and practical to implement in the BSES-CSIRO variety improvement program.

    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.

    AGR2008150 : Provision of research and development services for the Ord Sugarcane project
    (2009) Croft, BJ; Webb, B; Piperidis, G
    BSES has provided the research and extension services to the Ord River Irrigation Area (ORIA) sugar industry under a cooperative agreement with the WA Dept of Agriculture and Food since 2003. This contract was terminated in April 2008 after the Ord sugar mill ceased operations in 2007. A new contract was signed to provide continued Plant breeding and plant pathology services to WA Dept of Agriculture and Food to continue plant-breeding trials, inspect sugarcane plots for diseases and pests and to advise WA Dept of Agriculture and Food on maintenance of sugarcane varieties so they could be available for potential new sugar industries in the ORIA.

    Reducing the Australian sugar industry's genetic vulnerability to sugarcane smut : SRDC final report BSS256
    (2007) Croft, BJ; Berding, N
    Sugarcane smut was recorded for the first time in Australia in July 1998 in the Ord River Irrigation Area (ORIA) and was identified in the Bundaberg/Isis, Central and Herbert regions of Queensland in 2006. Sugarcane smut can cause losses from 30-100% in susceptible varieties. The objective of this project was to rate Australian commercial varieties, advanced selections in the BSES/CSIRO selection programs, and parental clones for resistance to smut. The ratings will be used to provide smut- resistant varieties to the Australian sugar industry and to assist the breeding program to increase the frequency of smut-resistant genes in breeding populations.This project continues the work commenced in the SRDC project BSS214 Screening of Australian Germplasm for Resistance to Sugarcane Smut. The smut-screening trials were conducted on Madura Island by the Indonesian Sugar Research Institute (ISRI) under contract to BSES.

    Literature review of methods of improving the germination of sugarcane : SRDC final report BSS208
    (2000) Croft, BJ
    Sugarcane is propagated from vegetative cuttings of the stalk (setts or billets). The cuttings can be planted by hand or through mechanical whole-stalk or billet planters. Billet planters have given variable results because of damage to the billets and uneven delivery of the billets into the furrows. Germination of the buds on the sugarcane cuttings is affected by temperature, moisture in the sett and the soil, plant hormones and the availability and rate of release of reducing sugars (eg glucose) within setts. Pineapple disease caused by the fungus, Ceratocystis paradoxa, rots setts of cane and can cause total germination failures. Wireworms (Agrypnus variabilis and Heteroderes spp) attack the buds and can cause poor germination.The speed of germination and the percentage of buds that germinate can be improved by soaking setts in water, short hot water treatment, pre-treatment of planting material with nutrients including nitrogen and application of mercurial fungicides. Except for the fungicide, these treatments have practical problems for application in commercial planting. Coating setts with materials to protect them from fungal and insect attack and to provide ideal conditions for germination is an attractive concept but no practical methods for achieving this concept have been reported.
