Introgression of erianthus germplasm into the saccharum gene pool & Investigation of the saccharum spontaneum contribution to commercial clones by genomic DNA In SITU hybridisation : SRDC Final reports BS115 & BS139

Abstract

Project objectives:

BS115

Evaluate a range of methods and the use of genetic bridges to overcome barriers to hybridisation between commercial clones and Erianthus arundinaceus. Develop methods to reliably confirm integeneric hybrids. Develop a more complete understanding of chromosome behaviour in sugarcane, particularly during introgression of related species.BS139S: Identify the contribution of Saccharum spontaneum to a number of cultivars that perform well in either tropical or subtropical/temperature regions. Determine the level of recombination between S. officinarum and S. spontaneum chromosomes in these clones. Describe the S. spontaneum chromosome transmission during the nobilisation process. Assess the potential of irradiation to enhance recombination between S. officinarum and S. spontaneum in interspecific materials.
