Pasture Variety Trial Network PVTN An evidence-based credible independent audited system for producers to assess pasture varieties
Genetic gain in perennial ryegrass forage yield in Australia and New Zealand 17800 Genetic gain = 0.76%*** 16800 Total annual yield - kgDM/ha 15800 14800 13800 Genetic gain = 0.02 %NS 12800 11800 10800 1960 1970 1980 Year of commercialisation 1990 2000 2010 2020 From: Harmer, Stewart & Woodfield 2016
Assumed profit map Worst case scenario profit map Poor adoption due information market failure. 0% return on levy investment if market had or would have X% increase in dry matter kg/Ha/annum Better variety bred project B.PBE.00XX levy funded 10% adoption in 10 years Uninformed and/or unaligned retail agronomist makes poor recommendation. Additional $0.5m in of-farm value by 2020 0.05% increase in beef kg/Ha/annum New and better variety of xxx bred as part of normal breeding activities - funded by firm X% increase in dry matter kg/Ha/annum provided comparable or better innovation.

Opportunities for researchers Risk analysis Stability analysis - Persistence data will allow development of species and variety specific risk models to guide fit for purpose decisions. Update models APSIM Victorian Perennial Ryegrass. On-farm investment analysis based on PTN data. Protocol development PTN MUST reflect on-farm performance. Iterative improvement of system necessary to improve prediction ability. Protocol A predicts X % of on farm outcome, protocol B predicts Y %
PTN likely outcomes Higher producer profits via: More informed and profitable decisions Low risk pasture investments Better targeting of levy funds to genuine market failure Kickstart breeding in minor species? Increased pull through and utilisation of important pre- breeding activities Increased rates of genetic gain via increased commercial incentive to be the best This further improves producer profits.
