Cultivar Selector Tool

Using the Forage Value Index (FVI), this tool allows you to objectively select the most suitable endophyte and ryegrass cultivar combination for your farm. Select the relevant filters to obtain a list of appropriate cultivars.

Note: Within each star rating category, cultivars are randomly assigned an order, so please choose cultivars within a star rating category based on seasonal performance values. Short term (winter feed and 12 month) ryegrass FVI are calculated based on cultivar-specific seasonal dry matter (DM) yield data. Whereas the perennial ryegrass FVI are based on cultivar-specific seasonal DM yield data, and functional group average data for the seasonal metabolisable energy (ME) content and persistence traits.

			Performance Values (1-5 rating) Seasonal dry matter (DM)					Performance Values (Relative to Mid Heading Diploids) Seasonal metabolisable energy (ME) The seasonal metabolisable energy (ME) content performance values for perennial ryegrass are calculated as the average of their functional group. Analysis of trials showed that there are three main ‘functional groups’ of perennial ryegrass for the seasonal ME content trait. These include mid heading diploids, late heading diploids and tetraploid perennial ryegrasses. We aim to include cultivar-specific data for this trait in the future. The 'genetic base' for the ME content trait was set as the average of the mid heading diploid cultivars, hence those cultivars have zero performance values for the ME content trait.

FVI (Star Rating)	FVI STAR RATING ($/ha)	Please note that in the Cultivar Selector Tool, cultivars within each star rating category are randomly assigned an order, but in the exportable FVI Lists, they are listed alphabetically. For more info please see the FVI Handbook at http://www.dairynz.co.nz/fvi	Cultivar	Winter	Early Spring	Late Spring	Summer	Autumn	Winter	Early Spring	Late Spring	Summer	Autumn	Persistence Scaler	The persistence scaling factor scales the 3-year National Forage Variety Trial (NFVT) data for seasonal dry matter yield by the expected yield over a 10-year period for diploid versus tetraploid perennial ryegrass cultivars. For more information, see the FVI Handbook at www.dairynz.co.nz/fvi.	Relative Renewal Cost ($/HA)	The relative renewal cost is the relative pasture renewal cost of diploid versus tetraploid perennial ryegrass cultivars, accounting for differences in relative persistence over the long term and costs of pasture renewal. For more information, see the FVI Handbook at www.dairynz.co.nz/fvi.	Endo	Ploidy	Heading Date	Marketer	Conf	Conf refers to the ‘Confidence’ based on the number of dry matter yield trials in the regions weighted by the DM trait correlations.
