AB Hague

Barley

Variety Description

Variety used for comparison: 'CDC Austenson'

Summary: At booting, the flag leaf of 'AB Hague' is narrower than that of 'CDC Austenson'. The spike of 'AB Hague' is lax while that of 'CDC Austenson' is of a medium density. The spike, excluding the awns, of 'AB Hague' is longer than that of 'CDC Austenson'. The sterile spikelet of 'AB Hague' has a parallel attitude while that of 'CDC Austenson' has a parallel to weakly divergent attitude.

Description:

YOUNG PLANT: semi-erect growth habit at tillering, absent or very sparse pubescence on lower leaf sheaths
PLANT: two row, spring feed barley, low frequency of plants with recurved flag leaves, spike emergence occurs mid-season

FLAG LEAF (AT BOOTING): sparse pubescence on blade
FLAG LEAF SHEATH: medium glaucosity, sparse pubescence
AURICLES: medium intensity of anthocyanin colouration, sparse pubescence on margins

SPIKE: medium glaucosity, semi-erect attitude, cup shaped collar, tapering, lax, parallel attitude of sterile spikelet, glume and awn of the median spikelet are equal in length relative to the grain
LEMMA AWNS: weak intensity of anthocyanin colouration of tips, longer than spike, rough spiculations on margins
FIRST SEGMENT OF RACHIS: medium length, medium degree of curvature

KERNEL: long rachilla hairs, husk present, weak anthocyanin colouration of nerves of lemma, weak spiculation of inner lateral nerves of dorsal side of lemma, absent or very weak degree of hairiness of ventral furrow, clasping disposition of lodicules, transverse crease shaped basal markings, medium in length and width

AGRONOMIC CHARACTERISTICS: good resistance to lodging, good resistance to shattering, good tolerance to straw breakage, good tolerance to drought, poor malting quality

Origin & Breeding History: 'AB Hague' (experimental designations TR18647 and T07041002003) originated from the cross between varieties 'Xena', as the female parent, and H94061120, as the male parent, conducted in 2007 at the Alberta Agriculture and Forestry Field Crop Development Centre in Lacombe, Alberta. The F2 seed was bulked in Lacombe in 2008 and entered into a single seed descent program with the F3 and F4 grown indoors during the winter of 2008-2009, in Lacombe, Alberta. Selected F4 heads were grown as F5 headrows in the field, in 2009. One line was designated T07041002003 and was tested for yield and disease resistance from 2010 to 2014 and was entered in the Western Cooperative Six-row Barley Test (Coop) as TR18647 in 2015. Selection criteria included grain and forage yield, test weight, kernel weight, lodging resistance, disease resistance, maturity as well as feed and forage quality.

Tests & Trials: The comparative trials for 'AB Hague' were conducted during the 2020 and 2021 growing seasons at Olds College Field Crop Development Centre in Lacombe, Alberta. The trial was arranged in a RCB design with 3 replicates. Each plot consisted of 8 rows with a row length of 2.5 metres. There was 0.14 metre inter row spacing with 0.4 metres between the plots. The seeding density was 269 seeds per squared metre resulting in approximately 2250 plants per variety. Measured characteristics were based on 30 measurements per variety per year. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
