Variety Description

Varieties used for comparison: 'CDC Ptarmigan' and 'Radiant'

Summary: The plant growth habit at the 5-9 tiller stage of 'Pintail' is semi-erect whereas it is semi-prostrate in 'CDC Ptarmigan'. 'Pintail' has medium frequency of plants with recurved flag leaves whereas it is high frequency for 'CDC Ptarmigan'. The flag leaf at booting of 'Pintail' is shorter and narrower than 'CDC Ptarmigan'. 'Pintail' has a medium glaucosity of the flag leaf sheath whereas it is weak for 'CDC Ptarmigan'. Heading of 'Pintail' is sooner than 'CDC Ptarmigan'. The spike of 'Pintail' has awnlets whereas 'CDC Ptarmigan' has no awns and 'Radiant' has awns. At maturity, the spike and awns of 'Pintail' are white whereas they are brown for 'Radiant'. 'Pintail' has a medium width shoulder of the lower glume whereas it is narrow for 'Radiant'. The shape of the shoulder of the lower glume for 'Pintail' is slightly sloping whereas it is sloping for 'Radiant'. 'Pintail' has a medium length lower glume whereas it is long for 'Radiant'. The width of the lower glume of 'Pintail' is medium whereas it is narrow for 'Radiant'. 'Pintail' has a medium length beak of the lower glume whereas it is long for 'Radiant'. 'Pintail' has a medium plant maturity whereas it is late for 'CDC Ptarmigan'. The kernel type is hard red for 'Pintail' whereas it is soft white for 'CDC Ptarmigan'. 'Pintail' has medium red kernel colour whereas they are white for 'CDC Ptarmigan'. The Stem Rust (Puccinia graminis f. sp. tritici) resistance of 'Pintail' is moderately resistant to moderately susceptible whereas it is susceptible for both 'CDC Ptarmigan' and 'Radiant'. 'Pintail' is moderately resistant to Stripe Rust (Puccinia striiformis) whereas 'CDC Ptarmigan' is susceptible.

Description:

PLANT: common hard red winter type, semi-erect growth habit at the 5-9 tiller stage, medium maturity

SEEDLING (4 LEAF STAGE): absent or very weak intensity of anthocyanin colouration of the coleoptile, glabrous sheath and blade of the lower leaves

FLAG LEAF (AT BOOTING): medium frequency of plants with recurved flag leaves, absent or very weak intensity of anthocyanin colouration of the auricles, medium glaucosity of the sheath, glabrous blade and sheath

SPIKE: weak glaucosity at heading, tapering shape in profile, lax to medium density, awnlets present, awnlets shorter than the length of the spike
SPIKE (AT MATURITY): white, incline attitude, absent or very sparse hairiness of convex surface of apical rachis segment
AWNS (AT MATURITY): white
CULM: weak glaucosity at heading, straight neck
STRAW (AT MATURITY): thin pith in cross-section, no anthocyanin colouration

LOWER GLUME: medium width, medium length, sparse extent of internal hairs
LOWER GLUME SHOULDER: medium width, slightly sloping shape
LOWER GLUME BEAK: medium length, slightly curved
LOWEST LEMMA: slightly curved beak
KERNEL: hard red type, medium red colour, small to medium size, short to medium length, medium width, oval to elliptical, rounded to angular cheek shape, short to medium brush hairs, round to oval medium sized germ, medium to wide crease, medium to deep crease

AGRONOMICS: good winter survival, poor resistance to pre-harvest sprouting, 29.5 grams per 1000 kernels, 10.5% protein

DISEASE REACTION: moderately resistant to Powdery Mildew (Erysiphe graminis f.sp. tritici) and Stripe Rust (Puccinia striiformis), moderately resistant to moderately susceptible to Stem Rust (Puccinia graminis f. sp. tritici), moderately susceptible to Leaf Rust (Puccinia triticina), susceptible to Fusarium Head Blight (Fusarium graminearum, Fusarium species) and highly susceptible to Common Bunt (Tilletia caries, Tilletia foetida)

Origin & Breeding History: 'Pintail' (experimental designations W460 and 00H050) is a double haploid line derived during 2001 from 98W049 in Lacombe, Alberta. 98W049 was created in 1998 and has the following pedigree: 93W022 / 'CDC KESTREL' // 'CDC CLAIR' / 3 / 'AC READYMADE' / 4 / 83W020007 / 5 / 'CDC HARRIER'. 83W020007 is the result of a cross between 78W005002 and 'Norstar'. Selection occurred in growth rooms and field plots in 2001 and 2002 based on the selection criteria of winter survival, plant type and disease resistance. Yield trials were conducted at various locations from 2003 to 2010. 'Pintail' was entered into the C level Coop Trials from 2008 to 2010.

Tests & Trials: Test and trials for 'Pintail' were conducted during the 2011 and 2012 growing seasons in Lacombe, Alberta. Plot size was 2.8 meters squared and consisted of 8 rows. The row length was 2.5 metres with 14 cm spacing between rows. There were 3 replicates arranged in a complete randomized block design. Measured characteristics were based on 20 measurements per variety per year.
