Agzone 4 (north and eastern wheatbelt) - variety performance in Western Australia (2009-13) Summary Review production value graphs for wheat varieties to support you with variety selection. You can get an indication of how much more a variety is likely to yield in kilograms per hectare (kg/ha) compared to other varieties in that environment. It also provides an indication of the stability of the variety over a number of locations and years within an agzone or region. The analysis is based on Grains Research Development Corporation’s (GRDC’s) National Variety Trials (NVT) from 2009–13. It is recommended you consider a number of locations and years. NVT locations included in this report are: Binnu, Buntine, Cadoux, Mullewa and Pithara in the northern districts of agzone 4 Kellerberrin, Merredin, Mukinbudin, Narembeen and Wyalkatchem in the eastern districts of agzone 4 Table 1 Location details for NVT’s at Binnu in 2009, 2010 and 2011 Location details Sowing Date Binnu in 2009 Binnu in 2010 Yuna in 2011 27/05/2009 11/06/2010 29/05/2011

contribution in the presentation of results in this report. In addition appreciation of the GRDC for their financial support of the Department of Agriculture and Food, Western Australia’s wheat agronomy project DAW00218 which has enabled the collaboration with SAGI. Further information When using PVs for variety selection decisions it is recommended that you consider not just a single environment, but a number of environments, both in terms of location (trial site) and season (trial year). This gives an indication of the stability of a varieties performance over a range of condition The locations displayed are based on the agzone however additional sites may have been included as they will have relevance from a regional or district perspective. To identify the type of environment experienced at that site and year, additional information for each NVT site has been provided. At present the trial sowing date, growing season rainfall, previous crop history and soil pH are reported. Site correlation is a relativity measure that is included in the reporting. It indicates how the variety ranking of the trial resembles neighbouring trial result rankings within the current region and year.
