Variety Description

Varieties used for comparison: 'Major', 'AC Metcalfe' and 'Newdale'

Summary: The frequency of plants with recurved flag leaves is low in 'Cerveza' whereas it is absent or very low in 'AC Metcalfe'. The intensity of anthocyanin colouration of the flag leaf auricles of 'Cerveza' is medium whereas it is very weak on 'AC Metcalfe'. The intensity of anthocyanin colouration on the tips of the lemma awns of 'Cerveza' is very weak to weak to medium whereas it is very weak on 'AC Metcalfe'. The spikes of 'Cerveza' are longer than those of 'Major' and 'AC Metcalfe'. The first rachis segment of 'Cerveza' is longer than that of all reference varieties. The kernels of 'Cerveza' are longer than those of 'Major' and 'AC Metcalfe'. 'Cerveza' is resistant to true loose smut (Ustilago nuda) whereas 'Newdale' is very susceptible.

Description:

FLAG LEAF: low frequency of plants with recurved flag leafs, absent or very weak pubescence on blade
FLAG LEAF SHEATH: very strong glaucosity, absent or very weak pubescence
AURICLES: medium intensity of anthocyanin colouration, absent or very weak pubescence on the margins

SPIKE: emerges mid-season, medium to strong glaucosity, erect to semi-erect to horizontal attitude, v-shaped closed cup collar, tapering to parallel shape, medium density, parallel to weakly divergent to divergent attitude of sterile spikelet, glume and awn of the median spikelet is longer than the grain
FIRST SEGMENT OF RACHIS: short, very weak to strong curvature
LEMMA AWNS: very weak to medium intensity of anthocyanin colouration of the tips, longer than length of spike, rough spiculation on margins

KERNEL: absent or very weak intensity of anthocyanin colouration of nerves of the lemma at beginning of ripening, whitish aleurone layer, long rachilla hairs, husk present, weak to medium spiculation of inner lateral nerves of dorsal side of lemma, no hairiness of ventral furrow, clasping disposition of lodicules, horseshoe shape basal markings

AGRONOMY: fair to good resistance to lodging, very good malting quality

DISEASE REACTION: moderately resistant to moderately susceptible to Common root rot (Cochliobolus sativus, Fusarium spp.), Net blotch (Pyrenophora teres), Stem rust (Puccinia graminis) and Fusarium head blight (Scab) (Fusarium graminearum); perfect state (Gibberella zeae), resistant to moderately resistant to Spot blotch (Cochliobolus sativus), susceptible to Septoria speckled leaf blotch (Septoria passerinii), Scald (Rhynchosporium secalis) and Barley yellow dwarf virus and resistant to Covered smut (Ustilago hordie), False loose smut, Black semi-loose smut (Ustilago nigra) and True loose smut (Ustilago nuda)

Origin & Breeding History: 'Cerveza' (experimental designation 'TR06294') is a doubled haploid barley line developed from the cross 'TR251'/'Newdale'//'TR253'/'Newdale' made in the fall of 1998 at the Agriculture and Agri-Food Canada Brandon Research Centre, Brandon, Manitoba. Two seeds of the F1 generation were planted in each of 5 pots in July 1999. Spikes were collected for doubled haploid production and embryos developed. The anther culture treatment from the F1 plants produced numerous double haploid plants, one of which became BM9831D-290 which was transplanted in the greenhouse, grown to maturity and harvested in April 2000. In May 2000, BM9831D-290 was planted as a single progeny row in the field at Brandon and selected based on height, maturity, lodging resistance, general appearance and field disease reaction. It was bulk increased in a winter nursery in Leeston, New Zealand that winter. The following spring, BM9831D-290 was planted out as a single plot in a preliminary yield test with repeated checks in Brandon and further selected for various agronomic, disease resistance and quality characteristics. BM9831D-290 was advanced to replicated yield tests and further evaluated for malting quality from 2002-2004. In 2005, BM9831D-290 was advanced to the Eastern Prairie Barley Test. In 2006, BM9831D-290 was advanced to the Western Cooperative Two-row Barley Registration Test where is was tested for two years as TR06294. In 2007-08, further evaluations were conducted in the Collaborative Malting Barley Trials as part of the registration recommending process under the auspices of the Prairie Recommending Committee for Oat and Barley.

Tests & Trials: Tests and trials for 'Cerveza' were conducted in Brandon, Manitoba during the summers of 2009 and 2010. The trials consisted of 4 replicates of each variety arranged in complete randomized block design. Each plot measured approximately 4 metres long x 1 metre wide spaced approximately 0.5 metres apart with a row spacing of 0.18 metres. Measured characteristics were based on approximately 20 measurements per variety per year.
