New germplasm to develop more productive varieties with enhanced resistance to nematodes, pachymetra root rot and smut : final report 2011/344
(Sugar Research Australia Limited, 2016)Sugarcane industries around the world were transformed in the early 1900s when Dutch plant breeders working in Indonesia, and Indian breeders, working independently, developed sugarcane varieties derived from the wild ... -
Optimal plot size and replication for testing clones in early stages of selection : SRDC final report CSR017
(1998)The aim of CSRO 17 was to identifY optimal plot design, replication and selection criteria for testing and selecting clones in small plots in early stages of selection in sugarcane breeding programs. Problems associated ... -
Optimisation of experimental design and analysis for variety trials to maximise genetic gain : SRDC final report UQ023
(2001)The analysis of field experimental data usually assumes independent observations. This method is often inappropriate if the data contain strong spatial trends. Methods of analysis (commonly used in cereal trials) which ... -
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 ... -
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 ... -
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 ... -
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 ...
