Map-based chromosome and trait tagging in sugarcane using cytological and RFLP markers
(1999)Sugarcane is a complex aneuploid, polyploid, interspecific hybrid. At the time that this project began, molecular mapping in sugarcane was in its infancy and was only being attempted in interspecific crosses or within the ... -
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: -
Field performance of transgenic sugarcane plants carrying genes for resistance to SCMV : final report BSS154
(2000)The field resistance of transgenic sugarcane plants to sugarcane mosaic potyvirus was successfully demonstrated, and a number of transgenic lines are available for consideration for agronomic evaluation. Some of the ... -
GxE interactions on ratooning of genotypes under trash blankets under cool/wet conditions : SRDC final report BS169S
(2000)This project was established to investigate the magnitude of the genotype by environment interaction effect for ratooning under a trash blanketing under cool/wet conditions. A population of 50 genotypes was deemed necessary ... -
Literature review of methods of improving the germination of sugarcane : SRDC final report BSS208
(2000)Sugarcane is propagated from vegetative cuttings of the stalk (setts or billets). The cuttings can be planted by hand or through mechanical whole-stalk or billet planters. Billet planters have given variable results ... -
High day temperature inhibition of sugarcane flowering : SRDC final report BSS158
(2000)The objectives of this project was to determine the sensitivity of the floral initiation process in sugarcane to day temperatures exceeding 32?C.The objective was not achieved because no meristems were initiated in the ... -
Sugarcane smut variety screening in the Ord : final report WAA002
(2000)A sugarcane smut screening trial was initiated in the Ord with planting in September 1999. Eighty-four cane varieties were rated for sugarcane smut susceptibility. Varieties included those introduced through SRDC project ... -
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 ... -
Transformation of sugarcane using Agrobacterium tumefaciens : final report on CTA027
(2000)A method for Agrobacterium-mediated transformation of sugarcane tissues has been developed in this project. This method offers an alternative technique for the introduction of transgenes into sugarcane. In general, ... -
Development of transformation cassettes for sugarcane : SRDC final report QT002
(2000)There are currently few gene regulation sequences (promoters/terminators) which have been shown to be effective in sugarcane. At present, the industry standard gene regulatory sequences used for genetic engineering of ... -
Duplication of photoperiodic initiation facility at BSES : SRDC Final report BSS218
(2000)Partnership-funded research by SRDC and BSES has resulted in excellent flowering being obtainable in populations of parental sugarcanes that flowered reluctantly, or never, under natural conditions at BSES Meringa. This ... -
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 ... -
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 ... -
Australian component Genetic diversity within Sugarcane yellow leaf virus : ICSB final report 99-15
(2001)Sugarcane yellow leaf virus (SCYLV) is widespread in many sugarcane growing countries of the world. The aim of this study was to determine the extent of genomic variation in SCYLV isolates from various countries. Isolates ... -
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 ... -
Analysis of sugarcane productivity trends in the wet tropics at a district level : SRDC final report
(2001)This project provided an in-depth re-analysis of district level data for cane yield, sugar content, and sugar content per hectare for the mill districts of Mulgrave, Babinda, and Tully and an evaluation of the estimates ... -
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 ... -
Breeding clones with high early sugar content : SRDC final report BSS93
(2002)The project BSS25 ?Breeding of clones with high early sugar content? concluded that the potential for increasing CCS through breeding and selection was greatest early in the season. BSS25 commenced a recurrent selection ... -
Evaluation and re-structuring of regional selection programs to maximise efficiency and speed of cultivar release
(2002)Continual delivery of new cultivars is required to maintain resistance to existing and new pests and diseases, and to provide constant improvement in crop productivity, quality and profitability for an internationally ...
