Wheat

Variety Description

Varieties used for comparison: 'Carlisle' and 'Maxine'

Summary: The flag leaves of 'Stanford' are longer and narrower than those of both reference varieties. The plants of 'Stanford' are shorter than those of both reference varieties. 'Stanford' matures mid-season whereas 'Carlisle' matures early. The straw pith of 'Stanford' is thin in cross section whereas it is medium to thick in 'Carlisle'. The spike of 'Stanford' is shorter than that of 'Carlisle'. The lower glume of 'Stanford' is long with a moderately curved beak whereas it is medium length with a slightly curved beak in 'Maxine'. The beak of the lower glume of 'Stanford' is very long whereas it is long on 'Carlisle' and medium length on 'Maxine'.

Description:

PLANT: winter type, mid-season maturity
SEEDLING (at four leaf stage): absent or very weak intensity of anthocyanin colouration of coleoptile, glabrous lower leaf sheath and blade

GROWTH HABIT (at 5-9 tiller stage): erect
FLAG LEAF (at booting): very low frequency of plants with recurved/drooping flag leaves, no anthocyanin colouration on auricles, medium to strong glaucosity on sheath, glabrous blade and sheath

SPIKE: tapering, medium to dense, weak glaucosity,white in colour with inclined attitude at maturity
CULM: weak to medium glaucosity, medium curvature at maturity
STRAW: thin pith in cross section, no anthocyanin colouration at maturity
AWNS: awns present, short, spreading, white

LOWER GLUME: narrow to medium width, long, glabrous
LOWER GLUME SHOULDER: slightly sloping to straight, narrow
LOWER GLUME BEAK: moderately curved, very long

KERNEL: hard red type, dark red, medium to large, medium length, medium width, elliptical shape, rounded cheek, long brush hairs, large oval germ
KERNEL CREASE: medium width, mid-deep

PERFORMANCE CHARACTERISTICS: fair to good winter survival, good bread making quality

DISEASE REACTION: moderately susceptible to Septoria avenae blotch (Septoria avenae f. sp. triticea), moderately resistant to Powdery mildew (Erysiphe graminis f. sp. tritici), Fusarium head blight (Fusarium graminearum, Fusarium species), Leaf rust (Puccinia triticina), and Stem rust (Puccinia graminis f. sp. tritici)

Origin & Breeding History: 'Stanford' is the result of the cross 712-91/FR84-8 made in 1991 in Schwabisch Hall, Germany. Single plant selection was used from the F3 to F6 generations based on yield potential, resistance to lodging, milling and bread making quality and disease resistance. The F7 was bulked by random selection of the progeny of 600 single F6 plants. 'Stanford' was tested as ACS52062.

Tests & Trials: The tests and trials for 'Stanford' were conducted in Palmerston, Ontario during the 2008 and 2009 growing seasons. A 4 replicate RCB design was planted with each replicate consisting of 8 rows, measuring 4 metres in length, seeded at a rate of 400 seeds/square metre. Measured characteristics were based on a mean of two years, with 20 measurements recorded each year.
