About National Variety Trials

The NVT Program

The NVT program was established in 2005 by the Grains Research and Development Corporation (GRDC). It is a national program of comparative crop variety testing with standardised trial management, data generation, collection and dissemination. This is managed through an internet accessed database that ensures a common approach and uniformity across the system. The NVT program initiation was driven by the increasing commercial focus of plant breeding programs in Australia, and the NVT system has been developed to complement the plant breeding industry. NVT accept lines into the program for testing two years prior to their commercial release. This ensures sufficient data is available for growers on newly released varieties to make informed variety selection decisions. NVT trials are managed according to agreed protocols. Contracted Service Providers manage the trials and ensure the national collection of standardised trial data into a single database. NVT is supported by the Australian Government and growers through the Grains Research and Development Corporation (GRDC)

The NVT Online Website

The NVT Online website is the delivery method for the NVT program. It is a website that draws upon reports and tables generated from the NVT database. The Google Map delivery system enables all crop specific information (including trial results, sowing guides, End Point Royalty, etc) for an entire state to be delivered to the user at a "Site Near You". The Long Term Yield Reporter (https://app.nvtonline.com.au/) presents robust analysed yield predictions using data from the multi-year MET (Multi Environment Trial) analysis. This is the most reliable data for assessing and comparing yield performance. Crops tested
  • Wheat
  • Barley
  • Canola
  • Chickpea
  • Faba Bean
  • Field Pea
  • Lentil
  • Lupin
  • Oat
  • Sorghum
More than 650 trials are sown at over 300 locations each year in the NVT system. Prior to 2020, the NVT database also captured breeding trials from the National Breeding Initiatives for Chickpea, Faba Bean, Field Pea, Lentil, Lupin and Oat. An additional 100 National Breeding Initiative trial results are also available for years 2019 and earlier.   Follow us on Twitter:
