The wheat variety selection tool is comprised of two main interfaces, the wheat class and region selector and the wheat variety comparison grid. For users on mobile devices there is also a mobile specific version of the tool designed for easier use with touch screens and smaller resolutions.
To start using the tool you will select the class of wheat you wish to see data for and then select what precipitation region you are in. You can do this either by clicking on the precipitation map in the area you are considering planting, or you can click directly on the legend icons that represent the different rainfall zones. As you move your mouse cursor around the precipitation map you will see the corresponding legend icon become highlighted. Additionally you will notice that there is a legend icon titled 'irrigated'. There is no corresponding map region for the irrigated legend so you must click on the legend icon in order to view data for irrigated trials.
Once you have selected a wheat class and clicked either on the precipitation map or legend icon you will be redirected to a page with a data grid for that wheat class and precipitation zone. Note that not all wheat classes have data for all precipitation zones, such as hard wheat not having data for irrigated trials. When the data grid loads you can drag and drop the column headers to re-order the columns as well as click the column headers to sort the data in various ways. You can also perform a multi-column sort with as many columns as you wish by shift-clicking on the column headers in the order that you want the sort order to occur. When you click on the same column header multiple times you will toggle the sort order between ascending and descending.
You can access additional data about each variety listed by clicking on the name of the variety in the data grid. This will redirect you to a variety details page that includes some descriptor data not included in the grid such as originator, glume, and awn, as well as a image and summary of the variety. Additionally you can bookmark any of the pages and be able to return to exactly those results at a later time, including the data grid and detailed views.
Some of the data in the grid uses numerical values to indicate aspects of the varieties performance. The following key explains what these values mean.
Disease Scale Key
- 1,2 = Resistant
- 3,4 = Moderately Resistant
- 5 = Moderate
- 6,7 = Moderately Susceptible
- 8,9 = Susceptible
Disease ratings are based on recently observed symptoms but data are limited in scope. Disease ratings can change and should be used as relative comparisons.
- '--' Indicates that no data is available
