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 ... -
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 ... -
An assessment of the application of DNA markers to studies of genetic diversity and marker assisted selection in sugarcane : SRDC Final report SD99001
(1999)The project objectives were as follows: -
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) ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Genotype X environment interaction and selection of sugarcane families for the Burdekin River irrigation area : SRDC final report BS57S
(1995)The arable lands being developed for sugarcane production in the Burdekin River Irrigation Area (BRIA) are on markedly different soil types and, as a consequence, may present environmental challenges different to those ... -
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 ... -
The production of transgenic sugarcane plants : SRDC final report BS44S
(1994)Transgenic sugarcane plants, which expressed the coat protein of SCMV at a very low level, were produced by micoprojectile bombardment of sugarcane meristems. Transgenic plants expressing the luciferase (Luc) and B-glucuronidase ... -
The promotion and delay of flowering
(1979)Several aspects of promoted flowering and delayed flowering were examined in small experiments at Meringa. These have application in the controlled flowering of parent varieties to facilitate a greater range of parent ... -
Biomass accumulation in sugarcane : final report 79/9028
(1984)Growth analysis experiments were conducted at Ayr and Bundaberg from 1979 to 1982 to study biomass accumulation in plant and ratoon crops of sugarcane. Crops were planted and ratooned in March, June, September and December, ...
