Optimisation of the initial stages of the New South Wales selection program : SRDC final project report BS96S
(2002)The main aim of this project was to obtain the basic information required to implement an efficient and effective breeding and selection program in NSW. However, the project suffered major difficulties that affected 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 ... -
Optimising productivity and variety recommendations through analysis of mill data : Final report 2016/32
(Sugar Research Australia Limited, 2021)The annual productivity of the Australia sugarcane industry fluctuates significantly across most sugarcane growing regions. Although some of this regional variation can be explained by extreme weather events or disease ... -
Optimum family felection for net merit grade : stage 2 trials BS45S
(1996)Mass selection of individuals in seedling or early clonal stage trials is routinely used in most sugarcane improvement programs throughout the world. It is, however, inefficient as the Heritability of cane yield on a ... -
Optimum plot shape for variety trials - effect of competition between varieties : Final report 39905083
(1991)Four plot shapes were compared using four replications of 60 clones. The shapes were 4-row long (4L), 4-row short (4S), 2-row long (2L) and 1-row long (1L). The standard length of 9.2m was used for long plots, short plots ... -
Optimum selection strategies in original seedlings particularly for heavily lodged crops : SRDC final report BS46S
(1999)The objectives for this project were: to evaluate the effectiveness of family selection in the plant crop of original seedlings of sugarcane grown to full crop potential in the Burdekin region. The crop will probably be ... -
Overcoming constraints to high yield and CCS in large and lodged cane crops
(2001)Past research indicates that large sugarcane crops (that usually also happen to be lodged) experience a slowdown in growth during winter, well before harvest (Muchow et al. 1996). The project examined factors affecting the ... -
Pathways to exploiting enhanced photosynthetic efficiency for higher sucrose and biomass yield
(2011)Australia has one of the highest commercial cane sugar (CCS) levels in the world but unfortunately CCS appears to have plateaud at about 14% of fresh cane weight over the past 20 years. Up to now in breeding programs, ... -
Perfect markers for sugarcane mapping
(2001)Sugarcane is a complex aneuploid, polyploid, interspecific hybrid. Most breeding traits are complex and molecular markers associated with these traits are a tool that may assist breeders to more efficiently identify sugarcane ... -
Production and evaluation of SCMV resistant transgenic sugarcane pests derived from transformed callus : SRDC final report BS94S
(1997)We have successfully demonstrated that sugarcane can be genetically engineered for resistance to sugarcane mosaic virus, using the coat protein gene of the virus to mediate resistance. At present the frequency of plants ... -
Production of an automated cane billet sampler for research trials : SRDC final report BSS156
(2000)Sugarcane breeding and research programs currently rely on hand-cut sound whole-stalk samples for determination of commercial cane sugar (CCS) and other quality components. These samples of sugarcane are free from extraneous ... -
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 ... -
Provision of improved varieties and pathology services for the Ord Sugar Industry : final report CTA043
(2003)This project was established to introduce and evaluate new sugarcane varieties into the Ord River Irrigation Area (ORIA), and to provide advice on pathology issues relating to the ORIA. Cultivars in the ORIA currently are ... -
Reducing the Australian sugar industry's genetic vulnerability to sugarcane smut : SRDC final report BSS256
(2007)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 ... -
Regeneration of sugarcane plants from protoplasts
(1991)This study aimed to develop a protoplast regeneration system for sugarcane so that gene transfer techniques could be applied for cultivar improvement. Published techniques for embryogenic callus culture, cell suspension ... -
Regeneration of sugarcane plants from protoplasts and application of genetic transformation systems to sugarcane
(1986)Current gene transfer systems developed for modifying plants include direct gene transfer to protoplasts and Agrobacterium mediated gene transfer. These studies have important practical implications for application of ... -
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 ... -
SaveN Cane : developing selection tools for N-efficient sugarcane
(2015)This project supports the sugar industry’s intensifying efforts to reduce its nitrogen (N) footprint that is caused by inefficient use of N fertiliser by the crop. The industry aims to minimise N pollution of coastal waters ... -
Seasonal distribution of growth and sugar accumulation in sugarcane : SRDC project BS5S Final report
(1995)At existing levels of cane yield, an extra unit of sugar content during May, June and July represented 47 6000 tonnes of sugar worth $13.3m at 1987 prices when this project was initiated. The situation now, with annual ...
