Two Senova varieties have been added to the winter oats Recommended List.


Balado is a conventional husked oat that yields 5% above Tardis, and a massive 9% improvement over market leader Gerald. But it is only a slight improvement in kernel content over those varieties, and nowhere near the quality of Brochan, Mascani and Dalguise.

“At the moment the breeders can either increase yield without increasing quality, or improve kernel content without the yields,” HGCA’s Jim McVittie said.

Balado was also a very short variety, with a provisional rating of nine for lodging resistance. Its straw length is 92cm compared with 111cm for Tardis and 120cm for Gerald.

“It’s a semi-dwarf,” explained Dr McVittie. Typically putting a dwarfing gene into oats had reduced height and yield, but the breeders were now including the dwarfing gene in their germplasm, and then breeding for height to get yield, he said.

“There is a desire to cut oat height to increase lodging resistance and negate the need for growth regulators on the crop, which processors are concerned about.”

The downside of Balado is its poor disease resistance. Its mildew resistance is only a four, while crown rust is a three. Despite that, and Tardis’s much better disease resistance, the untreated yield of both was similar, Dr McVittie said.

Fusion, a naked oat, could be a replacement for Grafton for growers aiming at markets requiring a higher specific weight, he said. “It has much less height and a similar specific weight.”

At just 93cm is it a almost 30cm shorter than Grafton, although not as short as Hendon at 84cm. Hendon, however, has a lower specific weight.

“It depends on the market you’re aiming at,” Dr McVittie said. “For poultry feed it doesn’t matter, but in the pet food market or buying for race horses it makes a difference.”

Fusion’s disease resistance was disappointing, he noted. Both mildew and crown rust are just threes.
