Environmental stimuli for sugarcane suckering in the wet tropics : SRDC final report BSS221
(2003)The northern section of the industry has been in crisis for most of the years in the decade up to 2002 because of declining CCS. This decline has been due to increased extraneous matter levels due largely to increased ... -
Maximising whole-of-industry benefits from the Australian sugarcane improvement program through an optimal genetic evaluation system
(2007)An optimal genetic evaluation system (GES) is the backbone of any breeding program because maximising genetic gains is primarily a matter of efficient selection. A GES provides information to breeders about which individuals ... -
Application of molecular markers to sugarcane breeding
(2006)The CRC SIIB marker application research aims to develop and evaluate ways to apply DNA markers to Australian sugarcane breeding programs to improve breeding, selection and fast release of high performing cultivars. This ... -
Understanding the reproductive biology and ecology of sugarcane to manage the safe release of genetically modified cultivars
(2010)This project set out to obtain basic and previously unavailable information on the ecology and sexual reproduction of sugarcane primarily so advances in sugarcane biotechnology can be utilised to the benefit of the Australian ... -
SRDC Research Project final report Increased CCS, cane yield and water use efficiency by exploiting interactions between genetics and management
(2009)In October 2003 delegates at an international workshop on sugarcane physiology funded by SRDC concluded that priority should be directed at a better understanding of traits responsible for high yield and high sucrose ... -
Knowledge of sugarcane physiology and climate-crop-soil interactions : SRDC final report
(2003)Compared to other crops, knowledge of growth mechanisms in sugarcane is inadequate. The question arises as to how much longer can we continue to prosper from sugarcane if knowledge of the growth processes on which our ... -
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 ... -
Development and application of spatial analysis to improve precision in selection trials : SRDC final report BSS231
(2004)In the early stages of selection, a sugarcane breeder tests a large number of genotypes. As the amount of planting material for each genotype for testing is typically limited, selections are usually made on small, ... -
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, ... -
Introgression of new genes from Saccharum officinarum
(SRDC, 2004)Modern sugarcane cultivars are derived from two main ancestral species: Saccharum officinarum, which is the main source of high sucrose levels, and S. spontaneum. Only a small number of clones of either species have ever ... -
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 ... -
Effect of far-red radiation on flowering of Saccharum spp. hybrids : SRDC Final report BS1S
(1990)Many tropical sugarcane clones (Saccharum spp. hybrids) are unavailable for hybridization because of poor flowering. Methods are required to improve the flowering of such clones. This study was conducted to determine whether ... -
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 ... -
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. ... -
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, ... -
Molecular tagging of economically important genes and promoters in sugarcane
(1992)Project Objectives : The overall aim of this project was to develop techniques for the isolation of useful gene control sequences (promoters) in sugarcane. Early in the project we also undertook preliminary studies to lay ... -
Effect of far-red radiation on flowering of Saccharum spp. Hybrids : SRDC final report BS1S
(1990)Many tropical sugarcane clones (Saccharum spp. hybr ids) are unavailable for hybridization because of poor flowering. Methods are required to improve the flowering of such clones. This study was conducted to determine ... -
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 ... -
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 ...
