Doriane

Barley

Variety Description

Varieties used for comparison: 'Cyane' and 'Boroe'

Summary: At tillering, the plants of 'Doriane' have an intermediate, between semi-erect and semi-prostate, growth habit while the plants of 'Cyane' have a semi-erect growth habit and those of 'Boroe' have an erect to semi-erect growth habit. At booting, the frequency of plants with recurved flag leaves is medium to high for 'Doriane' while the frequency of plants with recurved flag leaves is low for 'Boroe'. The anthocyanin colouration on the auricles of the flag leaf of 'Doriane' is of a weak to medium intensity while it is absent or very weak on the auricles of the flag leaf of 'Boroe'. The flag leaf of 'Doriane' is shorter than the flag leaf of 'Boroe'. The lemma awns of 'Doriane' have a strong intensity of anthocyanin colouration on the tips while the lemma awns of 'Cyane' have a weak intensity of anthocyanin colouration on the tips. The first segment of the rachis for 'Doriane' is short to medium in length while the first segment of the rachis is medium to long for 'Boroe'. When the caryopsis is hard, the glume and awn of the median spikelet is longer than the grain for 'Doriane' while the glume and awn are equal in length to the grain for 'Boroe'. The inner lateral nerves of the dorsal side of the lemma on the kernel of 'Doriane' has a weak to medium degree of spiculation while that of 'Boroe' has absent or very weak spiculation.

Description:

YOUNG PLANT: intermediate between semi-erect and semi-prostrate growth habit at tillering, absent or very sparse pubescence on lower leaf sheaths
PLANT: six row, spring barley, medium to high frequency of plants with recurved flag leaves

FLAG LEAF (AT BOOTING): absent or very sparse pubescence on blade
FLAG LEAF SHEATH: strong glaucosity, absent or very sparse pubescence
AURICLES: weak to medium intensity of anthocyanin colouration, absent or very sparse pubescence on margins

SPIKE: emerges mid-season, absent or very weak glaucosity, semi-erect attitude, open collar, parallel shape, medium density, glume and awn of the median spikelet are longer than length of grain
LEMMA AWNS: strong intensity of anthocyanin colouration of tips, equal to longer than length of spike, semi-smooth to rough due to presence of spiculations on two thirds to entire margin
FIRST SEGMENT OF RACHIS: short to medium, absent to very weak curvature

KERNEL: short rachilla hairs, husk present, absent or very weak anthocyanin colouration of nerves of lemma, weak to medium spiculation of inner lateral nerves of dorsal side of lemma, hairless ventral furrow

Origin & Breeding History: 'Doriane' (experimental designation CFO1505) originated from the cross conducted between 'Cyane', as the female parent, and 99050.18000000001, as the male parent, conducted in 2008 at La Coop Fédérée in Saint-Hyacinthe, Quebec. A modified mass selection technique was used from the F1 to F5 generations based on yield, maturity, lodging resistance, test weight, 1000 kernel weight and disease resistance. At the F5 generation, one line was designated CFO1505. Individual spikes, representing 29 lines at the F9 generation, were selected and bulked to establish breeder seed in 2015.

Tests & Trials: The comparative trials for 'Doriane' were conducted at La Coop Fédérée Research Farm in Saint- Hyacinthe, Quebec in 2019 and 2021. There were 4 replicates per variety arranged in an RCB design. In 2019, the size of the plots were 6 square metres and consisted of seven 5 m long rows spaced 0.18 m apart. In 2021, the size of the plots were 5 square metres and consisted of seven 4.5 m long rows spaced 0.18 m apart. The seeding density was 375 seeds per metre squared resulting in a minimum of 6500 plants per variety per year. Measured characteristics were based on 20 measurements per variety per year. Mean differences were significant at the 5% probability level based on a Tukey test.
