 The variety ‘Tyto’ is a 6-row hulless barley developed by the Field Crop Development Centre in Lacombe and marketed by Progressive Seeds Ltd.

Tyto is taller, higher yielding and slightly later than Falcon with 7% higher silage yield. We expect that it will replace Falcon in the dairy silage market. In Alberta, Tyto has higher grain yield than Falcon. It has good seed weight, test weight and high silage production.

Tyto was tested in the Western Cooperative Hulless Barley Trials and Field Crop Development Centre yield trials as HB513 and T89047103NX from 1996 to 2001 and received registration in 2002. It is a 6-row, smooth-awned, hulless feed barley. Tyto is semi-dwarf in height, with semi-compact medium-sized nodding spikes.

This variety has intermediate scald resistance, good resistance to surface-borne smuts, and resistance to stem rust and septoria. Similar to the check varieties, Tyto is susceptible to common root rot.

The Field Crop Development Centre data show Tyto tends to yield 2% to 12% more grain than Falcon in the 6.0 t/ha to 8.0 t/ha or greater production areas. Tyto also showed 7% higher silage yield than Falcon.
