To be included in the FVI database, each cultivar must have data from at least three trials that have been conducted using strict industry approved protocols. For Perennial ryegrass, trials must be three years in length, while Annual and Italian ryegrass trials must be a minimum of one full growing season.  \nReference varieties  \nAcross the three different species of ryegrass, the Performance Value is expressed asthe percentage change in yield relative to a selected reference cultivar that effectively acts as the genetic base for that species in the FVI.  \nFigure 1 Map of trial locations in Western Australia and South Australia that contributed to the FVI in 2026  \nBunbury  \nDardanup Boyanup  \nBusselton  \n Forest Grove  \nManjimup   \nFrankland  River  \nAlbany  \nThe reference cultivar is a well-known variety for each ryegrass species, where farmers and advisors are more likely to have a good understanding and knowledge of its performance over many years across various environments. The reference cultivars for each species are as follows:  \n• Perennial ryegrass: Victorian Ryegrass (Vic Rye).  \n• Annual ryegrass: Tetila (from a certified source to ensure consistency across trials).  \n• Italian ryegrass: Crusader.  \nWestern Australia FVI now available for 2026 sowing season  \nThe annual ryegrass FVI was first developed for Western Australia in 2024. This year, three additional trials were added to the database, including two trials from South Australia which are very similar agro-ecological zones to WA-Angaston and Gomersal. Unlike other trials locations in eastern Australia, these two sites were considered suitable for inclusion in the WA FVI due to the similarities in seasonal growing patterns with Western Australia's dairy farming regions. Before 2024, it was not possible to produce an FVI for the region as the PTN variety trials done in the eastern states of Australia, which have been used to create FVI lists for Victoria, Tasmania and NSW, were not suitable for use to create a WA-specific FVI. The reason for this is explained in greater detail in the Frequently Asked Questions document that can be found HERE on the Dairy Australia website. Briefly, it was evident that there was a substantial difference between how the same varieties of Annual and Italian ryegrass ranked in trials in WA, compared to on trial sites in the eastern states.  \nFor this reason, it was originally to use local trial data from WA only to create an   \nFVI for the region. It has taken a few years to obtain a critical mass of trial data that can be used to make an aggregated FVI list for WA. For the 2026 sowing season, 12 trials were completed and available to use that were conducted over the previous nine years in the high rainfall area of South-west WA, along with the 2 new trials from South Australia. The map shows the locations of each trial site in the WA FVI for 2026.  \nMain FVI list for Western Australia  \nUnlike the other regions in the FVI, there are no economic values used in the Western Australia FVI. Instead, varieties are ranked only on the basis of differences in total dry matter yield across the full growing season. The reference variety for the Annual ryegrass FVI in WA is Tetila, and this has a nominal value of 100 (representing 100 per cent). Every other variety in the list is measured against this standard. The cultivar at the top of the FVI list has a value of 105, for example. This means it produced 105 per cent of the total annual DM yield produced by Tetila on average,","cbCaimMeQFglXVA2","https://ap.wps.com/l/cbCaimMeQFglXVA2","pdf",1971205,10,"English","# Forage Value Index (FVI) overview\n# Reference varieties and performance value\n# Western Australia FVI for the 2026 sowing season\n# Main FVI list for Western Australia\n## Seasonal yield tables\n## Forage Quality","[{\"question\":\"What is the Forage Value Index (FVI) used for in Western Australia?\",\"answer\":\"The FVI helps Australian dairy farmers and advisors make informed decisions when selecting ryegrass cultivars by assessing their potential economic value and performance.
