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 ... -
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 ... -
Selection of a non-sugarcane gene for control of canegrubs : SRDC final report BS95S
(1996)Four types of non-sugarcane genes were investigation for potential toxictiy to canegrubs. They were: toxins from the bacterium Bacillus thuringiensis (Bt); plant proteinase inhibitors; plant lectins; and avidin. Each of ... -
Evaluation of methods of estimating breeding value of sugarcane parental clones : SRDC final report BS75S
(1996)BSES uses an empirically based index to assess the breeding potential of sugarcane (Saccharum spp.) parents and this may take many years to provide reliable estimates. A rapid and efficient method of assessing the breeding ... -
Selecting clones for better ratooning under wet harvesting conditions : SRDC final report CSR10S
(1997)There were three broad aims of this project: (i) To develop and evaluate a method for screening genetic material under conditions where there is (a) stool damage from harvesting machinery under wet conditions, and (b) ... -
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 ... -
Genotype X environment interaction for clones and crosses planted in Southern Queensland and Northern New South Wales : SRDC final report BS15S
(1997)The main aims of this project were to assess whether original seedling families produced for south Queensland would be suitable for the New South Wales sugar industry and to determine whether clones selected at the Bundaberg ... -
An automated cane billet sampler for research trials : SRDC final report BS118S
(1998)The Australian sugar industry invests millions of dollars annually on sugarcane breeding programs and associated research. Improved selection efficiency as a result of more accurate estimates of commercial cane sugar (ccs) ... -
Construction of synthetic Fiji virus resistance genes for use in sugarcane : SRDC final report BS86S
(1998)Fiji disease of sugarcane, caused by Fiji disease fijivirus (FDV), is one of the most important diseases affecting sugarcane in Australia. FDV is a member of the reovirus family and has a multipartite genome consisting ... -
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 ... -
Assessment of bulk segregant analysis and marker- assisted selection for economically important traits in sugarcane : SRDC final report BS138
(1998)The main aim of this project was to assess the feasibility of bulk segregant analysis (BSA) and marker-assisted selection for important traits in sugarcane. The target trait for this feasibility study was rust resistance. ... -
Maintaining access to foreign germplasm by developing methods to detect unidentified viruses in sugarcane in quarantine : SRDC final report BS116S
(1998)Four types of gneeric tests for detecting unidentified viruses in plants were trialed for their suitability for sugarcane. The tests were; double stranded RNA (dsRNA) analysis, sap inoculation of indicator plants, sap ... -
Fine mapping of major rust resistance gene in cultivar R570 with a view towards it closing through map-bases chromosome walking
(1999)A major gene for rust resistance has been identified in cultivar R570 (Daugrois et ai, 19%). Rust disease is caused by the fungus Puccinia malenocephala Syd P. Syd and is distributed worldwide. Inheritance of resistance ... -
Best linear unbiased prediction as a method for predicting cross potential : SRDC final report BS119S
(1999)Until recently, BSES breeders used an empirical formula to assess the breeding potential of a parent (Hogarth and Skinner, 1986). Although this method uses data from many sources, it needs to draw on data accumulated for ... -
The role of root growth and activity in determining sugarcane productivity : SRDC final report CLW002 (previously CSS02 & CSS2S)
(1999)Research conducted in this project aimed to better understand the relationship between root and shoot growth, in areas such as how the size of the root system affects shoot growth, do particular root parameters have a ... -
Building strategic research capacity for the sugar industry aimed at overcoming physiological, biochemical and environmental constraints to cane growth, breeding and sucrose yield
(1999)Using the CSIRO Controlled Environment Facility, the discrete effects on the rate and extent of sucrose accumulation in sugarcane of four significant environmental parameters (daily light integral, radiation levels, ... -
Efficient use of water resources in sugar production: a physiological basis for crop response to water supply
(1999)Although sugar is produced in the some of the most humid regions of Australia, water remains a major limitation to production. Experience in other rainfed and irrigated production systems in Australia has shown that use ... -
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 ... -
Genotype selection and management strategies for exploitation of responses to high planting densities : SRDC final report BS137S
(1999)The objectives of this project were to: evaluate the potential for high density planting (close row spacings) to increase yields over a range of conditions; assess the genetic potential available to exploit higher planting ...
