Registration of ‘Busby’ Barley

‘Busby’ (Reg. No. CV-343, PI 656596; CFIA Reg. No. 6540; Canadian PBR Appl. No. 08-6470) is a two-rowed, hulled, spring feed barley (Hordeum vulgare L.) developed at the Field Crop Development Centre (FCDC), Lacombe, AB, Canada. Busby was tested in FCDC trials as H94034003 from 2001 to 2005 and in Prairie Recommending Committee for Oat and Barley trials as TR06673 during 2006 and 2007. It was registered for production in western Canada due to its good combination of yield, agronomic performance, grain quality traits, and disease resistance. Busby is resistant to the surface-borne smuts (caused by Ustilago spp.) and moderately resistant to the spot form of net blotch (caused by Pyrenophora teres forma maculate Smedge). Busby has shown reactions to scald [caused by Rhynchosporium secalis (Oudem.) J.J. Davis] similar to the two-rowed cultivar Seebe that has proven to have durable resistance in Alberta, Canada.
