Wheat

Variety Description

Variety used for comparison: 'McClintock'

Summary: 'Peregrine' has medium intensity of anthocyanin colouration of the coleoptile while it is weak in 'McClintock'. At the 4 leaf stage, 'Peregrine' has very sparse to sparse pubescence of the sheaths of the lower leaves and glabrous blades of the lower leaves while it is medium pubescence on the sheaths and sparse pubescence on the blades in 'McClintock'. 'Peregrine' has a high frequency of plants with recurved flag leaves while it is medium frequency in 'McClintock'. The glaucosity of the flag leaf sheath in 'Peregrine' is medium while it is strong in 'McClintock'. 'Peregrine' has a longer flag leaf than 'McClintock'. 'Peregrine' heads slightly later than 'McClintock'. At maturity, the convex surface of the apical rachis segment of 'Peregrine' has absent or very sparse hairiness while it is medium hairiness in 'McClintock'. 'Peregrine' has a long beak length of the lower glume while it is medium length in 'McClintock'. The kernel of 'Peregrine' has a medium crease width while it is narrow in 'McClintock'.

Description:

PLANT: winter type, common wheat, prostrate growth habit at the 5-9 tiller stage, medium glaucosity of the culm at heading, high frequency of plants with recurved flag leaves

SEEDLING (4 leaf stage): medium intensity of anthocyanin colouration of the coleoptile, pubescent sheaths and glabrous blades of the lower leaves

FLAG LEAF: weak intensity of anthocyanin colouration of the auricles, medium glaucosity of the sheath, glabrous blade and sheath

STRAW (AT MATURITY): thin pith in cross-section, no anthocyanin colouration
SPIKE: weak glaucosity at heading, tapering profile, lax to medium density, awns present, awns shorter than the length of the spike
SPIKE AT MATURITY: white, whitish awns, nodding attitude, straight neck of the culm, absent or very sparse hairiness of convex surface of apical rachis segment
LOWER GLUME: very narrow to narrow shoulder, sloping to slightly sloping shoulder, medium length, narrow, pubescent, long moderately curved beak

KERNEL: hard red type, dark red colour, small to medium size, medium length, medium width, elliptical, angular cheek shape, medium to long brush hairs, small to medium sized round to oval germ, medium crease width, very shallow crease depth

AGRONOMY: good resistance to shattering, fair to good drought tolerance, good winter survival, fair to good resistance to pre-harvest sprouting

DISEASE REACTION: moderately susceptible to powdery mildew (Erysiphe graminis, f. sp. tritici) and moderately susceptible to Septoria tritici blotch (Septoria tritici)

Origin & Breeding History: 'Peregrine' (experimental designation DH99-37-100) is a winter wheat variety developed by the Department of Plant Sciences, University of Saskatchewan, Saskatoon, Saskatchewan. 'Peregrine' originates from the cross made in 1999 of McClintock / S86-808 using the doubled haploid method. Selection was made in field trials during 2001 to 2003 for agronomic traits and disease resistance.

Tests & Trials: Test and trials were conducted in 2009 and 2010 at C&M Seeds in Palmerston, Ontario. Plots consisted of 8 rows with a row length of 4 meters and a row spacing of 15 cm. Planting density was 400 seeds per meter squared. There were 4 replicates arranged in an RCB design.
