Exploiting introgression for the development of productive and regionally adapted varieties for NSW : final report 2013/022
(Sugar Research Australia Limited, 2020)This project aimed to explore sugar cane variety improvement opportunities available through introgression in relation to 2-year cropping, temperate cane growing conditions of NSW and frosting. It provided an opportunity ... -
Exploiting Erianthus diversity to enhance sugarcane cultivars : ASSCT peer-reviewed paper
(ASSCT, 2019)Introgression of Erianthus arundinaceus into the SRA sugarcane-breeding program has been a goal for researchers for many years. The Erianthus genome was finally accessible to sugarcane breeders with the identification in ... -
Effect of neonicotinoid, pyrethroid and spirotetramat insecticides and a miticide on incidence and severity of Yellow Canopy Syndrome : ASSCT peer-reviewed paper
(ASSCT, 2019)Yellow Canopy Syndrome (YCS) is a condition affecting Australian sugarcane that can lead to yield losses in excess of 30% in severely affected crops. The causal agent of this condition is unknown. Insect pests are well ... -
Starch accumulation in sugarcane in response to stress
(ASSCT, 2016)Yellow Canopy Syndrome (YCS) is a new problem affecting the Australian sugar industry. It was first reported in 2012 and has increased in occurrence and spread from the initial reports in North Queensland to further south ... -
Field evaluation of selected introgression clones for their resistance to root-knot nematodes : ASSCT peer-reviewed paper
(ASSCT, 2019)Sugarcane nematodes, root-knot (RKN) and root-lesion (RLN), cause an estimated loss of over $80 million per year to the Australian sugar industry. In particular, RKN is a major problem if sugarcane is planted in sandy soil. ... -
Prospects for a genetic solution to the management of ratoon stunting disease : ASSCT peer-reviewed paper
(ASSCT, 2021)Ratoon stunting disease (RSD,) caused by a bacterium (Leifsonia xyli subsp. xyli), is one of the most important diseases of sugarcane in Australia. RSD is an inconspicuous and highly infectious disease and can spread ... -
Genomic organisation of sugarcane cultivars revealed by chromosome-specific oligonucleotide probes : ASSCT peer-reviewed paper
(ASSCT, 2021)Sugarcane (Saccharum spp.) is probably the crop with the most complex genome. Modern cultivars (2n=100-120) are derived from interspecific hybridization between the noble cane S. officinarum (2n=80) and the wild cane S. ... -
Seed-based in vitro propagation to accelerate variety development : ASSCT peer-reviewed paper
(ASSCT, 2021)To shorten the current lengthy selection process in sugarcane breeding and to accelerate genetic gain, Sugar Research Australia is implementing a range of novel breeding strategies and selection tactics. One strategy is ... -
A field experiment to evaluate the response of sugarcane varieties to waterlogging
(ASSCT, 2018)RECENT PRODUCTIVITY REVIEWS in the Herbert and Central regions identified strong negative correlations between excessive rainfall and productivity. Waterlogging has a significant effect on sugarcane productivity. It ... -
Genetic control and genomic selection for important traits in sugarcane, and comparison of elite Indian and Australian germplasm : final report AISRF/48454

Sugarcane root systems for increased productivity; development and application of a root health assay : final report 2015/002
(Sugar Research Australia Limited, 2018)A better understanding of the sugarcane root system has the potential to improve productivity and overcome soil constraints. By adapting the digital methods that have been developed in other crops, we have developed a ... -
SUMO wrestling - understanding the molecular basis of drought tolerance in sugarcane : final report 2017/401
(Sugar Research Australia Limited, 2018)We report here that neither the plant growth hormone gibberellin (GA) signalling, nor SUMOylation post-translational mechanism, a well-known phenomenon triggered by several abiotic stresses, are involved in water stress-induced ... -
Reviewing and extending knowledge of fibre quality assessment within the SRA breeding program to develop optimally adapted varieties for the Australian sugar industry
(Sugar Research Australia Limited, 2018)This project aimed to improve knowledge of the significance of fibre quality measurement data to improve its value for variety selection and to provide guidance on further research work to utilise fibre quality requirements ... -
Investigation of lignin biosynthesis in sugarcane for improved lignocellulosic ethanol production: final report 2010/068
(Sugar Research Australia Limited, 2015)Second generation bioethanol is a renewable energy resource produced from lignocellulosic biomass with the potential to reduce reliance on oil-based energy. Sugarcane bagasse is an abundant source of lignocellulosic material ... -
Faster flowering - new opportunities for genetic improvement: final report 2012/024
(Sugar Research Australia Limited, 2015)In sugarcane, flowering is essential to breeding but is not a pre-requisite for commercial production. Consequently, our knowledge of the processes that control flowering lags behind other crops where the seed is the ... -
Optimising productivity and variety recommendations through analysis of mill data : final report 2014/054
(Sugar Research Australia Limited, 2016)Production peaked in the Herbert River mills in 2005 at 5.5 Mt, and in 2015 was 4.5 Mt. Cane and sugar yields during this period have also been below average, particularly in 2011, and significant areas went from growing ... -
Profit based measures to capture, evaluate and prioritise genetic improvement of water use efficiency and nitrogen use efficiency in sugarcane : final report 2014/302
(Sugar Research Australia Limited, 2016)Sugar Research Australia (SRA) contracted AbacusBio Pty Ltd with IDA Economics Pty Ltd to undertake a systems modelling project to estimate the relative economic value of two potential new performance traits of sugarcane ...
