Coralia

Wheat

Variety Description

Varieties used for comparison: 'AC Brio', 'Furano' and 'SS Blomidon'

Summary: At booting, the anthocyanin colouration of the auricles on the flag leaf of 'Coralia' is absent or very weak whereas it is of medium intensity for 'AC Brio' and of a weak intensity for those of 'Furano' and 'SS Blomidon'. The flag leaf of 'Coralia' is shorter than those of 'Furano' and 'SS Blomidon' and narrower than that of 'Furano'. The plants of 'Coralia' head earlier than the plants of 'Furano' and 'SS Blomidon'. At heading, 'Coralia' has a weak degree of glaucosity on the spike whereas the glaucosity is medium for 'Furano' and medium to strong for 'SS Blomidon'. At maturity, the plants of 'Coralia' are shorter than the plants of 'AC Brio' and 'Furano'. In profile, the spike shape of 'Coralia' is fusiform whereas it is tapering for 'Furano' and parallel-sided for 'SS Blomidon'. The hairiness of the convex surface of the apical rachis segment of 'Coralia' is sparse to medium whereas it is strong for 'Furano' and absent or very sparse to sparse for 'AC Brio'. 'Coralia' has a lower kernel weight than the reference varieties.

Description:

SEEDLING (4 LEAF STAGE): glabrous lower leaf sheaths

FLAG LEAF: absent or very weak intensity of anthocyanin colouration of auricles, medium to strong glaucosity of sheath, glabrous blade and sheath

STRAW (AT MATURITY): thin pith in cross-section

SPIKE: weak degree of glaucosity at heading, fusiform shape in profile, medium density, white at maturity, inclined attitude, sparse to medium hairiness of convex surface of apical rachis segment
AWNS: shorter than spike length, white at maturity
LOWER GLUME: glabrous
LOWER GLUME SHOULDER: narrow to medium width, straight
LOWER GLUME BEAK: short, slightly curved

KERNEL: medium red

Origin & Breeding History: 'Coralia' (experimental designations CFB1618 and C1M16057) was developed using the pedigree breeding method by Selgen a.s. in Stupice, Czech Republic. The initial cross took place in 2004 between 'Seance' and 'Prointa Oriental', which was subsequently crossed with 'SW Kadrilj'. The variety originates from a single plant selection in the F3 generation with subsequent selections in the F4, F5, F8, F9 and F10 generations. Breeder seed was established at the F11 generation in 2015. Selection criteria included yield, baking quality, lodging resistance and disease resistance.

Tests & Trials: The comparative trials for 'Coralia' were conducted at the La Coop Fédérée Research Farm in Saint-Hyacinthe, Québec in 2020 and 2021. There were 4 replicates arranged in a RCB design. In 2020, the size of the plots were 5 square metres and consisted of seven 5 m long rows spaced 0.18 m apart. In 2021, the size of the plots were 6 square metres and consisted of seven 4.5 m long rows spaced 0.18 m apart. The seeding density was 375 seeds per square metres resulting in a minimum of 6500 plants per variety per year. The measured characteristics were based on a 20 measurements per variety each year. Mean differences were significant at the 5% probability level based on a Tukey test.
