Abstract | This project aimed to explore sugar cane variety improvement opportunities available through introgression in relation to 2-year cropping, temperate cane growing conditions of NSW and frosting. It provided an opportunity to review the NSW selection program that has been operating since early 2000. |
Abstract | Traditionally, the top 25 performing clones from the NSW 1-year program would enter the NSW 2-year program for testing as a 2-year cane. In this project, selected introgression clones from project BSS344 plus varieties imported from the USA were directly included in the NSW 2-year selection program without first being tested in the 1-year program. These clones plus current commercial varieties were also included in frost observation plots for assessment for frost tolerance. |
Abstract | Saccharum spontaneum introgression clones were the most successful group to fast-track directly into the NSW 2-year program. One S. spontaneum introgression clone (SRAW18) was released to NSW growers in 2019/20 and it is highly likely that another S. spontaneum introgression clone will be released in 2020/21. Erianthus arundinaceus introgression clones and varieties from the USA generally did not perform well. |
Abstract | For the three years (2015-2017) the frost observation plots were monitored there were relatively few nights with temperatures below freezing (0°C), the coldest being -0.9°C on 9th August 2017. The light frost events resulted in no/little differentiation between clones and negatively impacted the selection of NSW clones for release and use as parents for the crossing program. |
Abstract | Based on results from this project, the NSW selection program was modified and will place further emphasis on introgression material for the 2-year program. |
