Barley

Variety Description

Varieties used for comparison: 'CDC Maverick' and 'Oreana'

Summary: At booting, the frequency of plants with recurved flag leaves is medium to high for 'CDC Renegade' while the frequency of plants with recurved flag leaves is low for 'CDC Maverick'. The anthocyanin colouration on the flag leaf auricle for 'CDC Renegade' is absent or of a very weak to weak intensity while it is of a medium intensity on the flag leaf auricle of 'CDC Maverick'. The flag leaf of 'CDC Renegade' is larger than those of 'CDC Maverick' and 'Oreana'. At maturity, the plants, including the awns, of 'CDC Renegade' are shorter than the plants of 'CDC Maverick' and taller than those of 'Oreana'. The spike of 'CDC Renegade' is very lax to lax while that of 'Oreana' is of a medium density. The spike, excluding the awns, of 'CDC Renegade' is longer than those of the reference varieties. The lemma awns of 'CDC Renegade' are shorter or equal in length compared to the spike while the lemma awns of 'Oreana' are longer than the spike. The lemma awns of 'CDC Renegade' are smooth while those of 'Oreana' have rough spiculations on the margins. Spiculation of the inner lateral nerves of the dorsal side of the lemma on the kernel of 'CDC Renegade' is absent or very weak while it is of a medium degree for 'Oreana'. The kernel weight for 'CDC Renegade' is less than that of 'CDC Maverick'.

Description:

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

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

SPIKE: weak to medium glaucosity, semi-erect to horizontal attitude, v-shaped to open collar, parallel shape, very lax to lax, reduced sterile spikelet, glume and awn of the median spikelet are longer than grain
LEMMA AWNS: absent or very weak to weak intensity of anthocyanin colouration of tips, shorter to equal than length of spike, smooth spiculations on margins
FIRST SEGMENT OF RACHIS: medium length, weak to strong curvature

KERNEL: whitish aleurone layer, long rachilla hairs, husk present, weak anthocyanin colouration of nerves of lemma, absent or very weak spiculation of inner lateral nerves of dorsal side of lemma, hairless ventral furrow, clasping disposition of lodicules, horseshoe shaped basal markings, medium in length and width

AGRONOMIC CHARACTERISTICS: fair resistance to lodging, good resistance to shattering, good tolerance to straw breakage, fair to good tolerance to drought

Origin & Breeding History: 'CDC Renegade' (experimental designations FB209 and SB140071) originated from the cross conducted between the varieties 'Xena' and SB090601 conducted in 2010 at the University of Saskatchewan Crop Development Centre in Saskatoon, Saskatchewan. The F1 and F2 generations were bulked in New Zealand in the winter of 2010-2011 and in Saskatoon, Saskatchewan in 2011, respectively. The F3 was bulked in New Zealand in the winter of 2011-2012 and the F4 space planted in Saskatoon in 2012. Selected F5 heads were grown as hill plots in Saskatoon in 2013 and the bulked F6 seed from one selected hill plot was designated as SB140071. SB140071 underwent yield trials from 2014 to 2017 and was tested in the Western Cooperative Forage Barley Registration Trials as FB209 in 2018 and 2019. Selection criteria included hull presence, awn smoothness, forage yield and quality, grain yield, physical grain quality, lodging resistance, maturity and disease resistances.

Tests & Trials: The comparative trials for 'CDC Renegade' were conducted during the 2020 and 2021 growing seasons at the University of Saskatchewan Crop Science Field Laboratory in Saskatoon, Saskatchewan. The trial was arranged in a RCB design with 4 replicates. Each plot consisted of 4 or 5 rows with a row length of 3.66 metres and 0.2 metre inter row spacing. The seeding density was 215 seeds per squared metre resulting in approximately 4500 plants per variety. Measured characteristics were based on a minimum of 24 measurements per variety per year, except for kernel weight, which was based on 10 measurements per variety per year. Mean differences were significant at the 5% probability level based on LSD values.
