Selection tool makes it easier to choose right cereal variety

A variety selection tool to help growers choose the most suitable winter wheats and spring barleys has been introduced by the Agriculture and Horticulture Development Board.

The tool is able to navigate AHDB recommended list trial data, make comparisons and identify the most promising varieties for individual farm situations. It will be expanded to cover additional crops on the recommended list this year.

Paul Gosling, head of the recommended list team, said the online tool was developed in response to requests by growers. “It doesn’t include any extra information but it makes it much easier to focus down on what is important to each individual farmer.”

Currently, the tool covers winter wheat and spring barley. Winter barley, winter oilseed rape and oats will be added this spring. At the same time, an RL app will be launched this spring to replace the AHDB’s crop specific pocketbooks.

Using the tool

The tool can be used in two main ways to narrow down the variety options available to farmers. The first is using  filters to select varieties with certain characteristics, explained Mr Gosling in an AHDB podcast to coincide with the launch of the tool.

“If you were looking for a Group 4 feed wheat in a second wheat position, you could use it to remove all the varieties with an eyespot rating of, say, below five. That immediately reduces you down to nine varieties.

“Then, if you said, well I don’t want to spend a fortune on fungicides, you could remove anything with a septoria rating of below 5.5. That leaves just one variety – Dunston. You may not want to grow Dunston for other reasons, but you can see how it would work.”

The second way to identify suitable varieties is agronomic merit. It is a way of combining multiple agronomic characteristics – such as disease resistance and lodging data – into a single measurement that can be assigned to a variety.

Adjusting settings

Different characteristics can be given different ratings. Septoria, for example, is given a higher rating than fusarium. Different areas of the country are given default ratings for each characteristic, depending on its likely impact. But these can be changed manually.

If you are in the west and you think yellow rust is of particularly high importance on your farm, you can can adjust the rating accordingly, says Mr Gosling. This really shines the spotlight on the varieties which can really make the biggest different on each individual farm.

Launched this spring, the RL app will be available for everyone to download. Unlike the old pocketbooks, which quickly went out of date, it will be updated throughout the season to reflect new developments, such as when candidate varieties are added to the recommended list.
