Variety Description

Varieties used for comparison: 'CDC Alamo' and 'CDC McGwire'

Summary: 'CDC Fibar' is a two-row, hulless, waxy barley variety that has a longer flag leaf than either 'CDC Alamo' or 'CDC McGwire'. The plants of 'CDC Fibar' are taller than the plants of 'CDC Alamo'. 'CDC Fibar' has a shorter spike than either of the reference varieties. The kernel of 'CDC Fibar' has long rachilla hairs, whereas 'CDC Alamo' has short rachilla hairs. The kernel basal markings of 'CDC Fibar' are incomplete horseshoe shaped, compared with both reference varieties which have transverse crease basal markings.


JUVENILE PLANT: erect to semi-erect growth habit
PLANT AT TILLERING: no pubescence on sheath of lower leaves, intermediate growth habit

FLAG LEAF: no pubescence on blade or sheath, moderate to strong anthocyanin on auricles

SPIKE: emergence mid-season, platform collar, erect to semi-erect attitude, weak glaucosity, parallel shape, dense, sterile spikelet parallel to weakly divergent, first segment of rachis medium length with moderate curvature
MEDIAN SPIKELET: glume and awn equal in length or longer than grain
LEMMA AWNS: weak anthocyanin at tips, longer than spike, rough (barbs from the tip to next to the kernel)

KERNEL: whitish aleurone layer, no husk, long rachilla hairs, no spiculation of inner lateral nerves of dorsal side of lemma, no hairs in ventral furrow, clasping lodicules, incomplete horseshoe basal markings, medium length, medium to broad width

AGRONOMIC TRAITS: good shattering resistance, good tolerance to straw breaking and neck breaking, fair to good tolerance to drought

DISEASE: moderately resistant to scald (Rhynchosporium secalis) and covered smut (Ustilago hordei), slightly susceptible to false loose smut, black semi-loose smut (Ustilago nigra), moderately susceptible to stem rust (Puccinia graminis) and net blotch (Pyrenophora teres) susceptible to fusarium head blight (Fusarium graminearum), very susceptible to spot blotch (Cochliobolus sativus) and true loose smut (Ustilago nuda)

Origin & Breeding History: 'CDC Fibar' was developed by the University of Saskatchewan, Crop Development Centre's non-malting barley breeding program, using a pedigee breeding system. It originated from the cross SB94789 x SB94892, made in 1994. The F1 through F3 generations were grown as bulk populations with the F1 and F3 grown in winter nurseries in New Zealand. 'CDC Fibar' (experimental number HB373) was grown and selected as a single F4 head in Saskatoon in 1996 and was subsequently sown as a F5 hill plot in 1997. The seed from that F5 hill plot was bulked as the line which became 'CDC Fibar'. It was tested in CDC yield trials in 1999-2001, followed by testing in the Western Canada Hulless Barley Cooop trial during 2002.

Tests & Trials: Tests and trials for 'CDC Fibar' were conducted in Neapolis, Alberta during 2005 and 2006. The trials consisted of 3 replicates of each variety, with each replicate consisting of 3 adjacent plots. The replicates were planted in an RCB design. Measured characteristics were based on a minimum of 15 measurements per variety per year.
