Like the new winter malting barley, spring type Scout from Nickerson is very susceptible to yellow rust (rated 2) and so merits only specific recommendation – as a feed variety for the north-east region.
“It couldn’t be considered for full recommendation,” says Mr Hanson.
However, it matches Waggon for treated yield and has outperformed that variety in north-east trials.
“It’s short and stiff and has good resistance to brackling.”
Its mildew and brown rust resistances are good. “But its five for rhynchosporium is really as low as you want to go.”
The three other newcomers, all fully recommended, are also short and stiff, he notes.
Sweeney is top rated for mildew and brown rust resistance. “But it’s a bit weak for yellow rust.”
“They tell me that it’s likely that Jolika will be a better bet to meet some of their requirements than the Tipple types.”
Jolika matches Tipple for yield, has good mildew resistance and is “pretty good” against rhynchosporium. But its brown rust resistance at four is low, he warns.
It may also have potential in the smaller grain distilling market which currently uses the much lower-yielding Decanter, notes Mr Hanson.
Its only moderate brown rust resistance should not be a problem in the areas likely to be growing it, and its rhynchosporium resistance rating of 7 should be of particular interest to Scottish growers, he suggests.
