Yield and cane-quality factors are important in determining the commercial success of each variety. These are determined by the Tully Variety Management Group through intensive small-scale sub-district trials to develop a voluntary Tully Recommended Variety list and associated guide. This provides confidence for commercial planting without having to conduct larger, longer-term strip trials or full-scale commercial crops that could fail early in the crop The commercial results show improvements in both yield and cane quality that reflect the success of TVMG through the speed of commercialisation (2-3 years instead of 4-5 years), and the commercialisation of pachymetra-resistant varieties in the higher risk areas. These improvements in yield and quality assist the milling process and its profitability.
