STEM: absent or very weak glaucosity of culm neck, weak curvature of culm neck, thin pith in cross section of straw, no anthocyanin colouration of straw at maturity

FLAG LEAF: very high frequency of recurving/drooping, glabrous sheath and blade, absent or very weak anthocyanin colouration of the auricles, medium glaucosity of the sheath

SPIKE: tapering shape, medium to dense density, erect attitude at maturity, weak to medium glaucosity, white colour at maturity, very short to short awnlets present, sparse to medium hairiness of convex surface of apical rachis
LOWER GLUME: narrow to medium width, short, glabrous, straight shoulder shape, medium width of the shoulder, straight beak shape, short to medium length beak, sparse internal hairs
LEMMA:straight beak shape
KERNEL: hard red type, dark red colour, small oval size, short length, narrow to midwide, angular to rounded cheek shape, short to midlong brush hairs, midsized round germ (embryo), midwide mid-deep crease

AGRONOMY: good shattering resistance, fair pre-harvest sprouting tendency, good bread qualities

DISEASE REACTION: susceptible to Common Root Rot (Cochliobolus sativus Fusarium species), Fusarium Head Blight (Fusarium graminearum Fusarium species) and Loose Smut (Ustilago tritici); moderately resistant to Black Point and Smudge (Cochliobolus sativus Alternaria species, Pseudomonas syringae pv. atrofaciens), Septoria tritici blotch (Septoria tritici), Septoria nordorum blotch (Septoria nodorum), Ergot (Claviceps purpurea) and Common Bunt (Tilletia caries, Tilletia foetida); moderately resistant to moderately susceptible to Leaf Rust (Puccinia triticina); and resistant to moderately resistant to Stem Rust (Puccinia graminis f. sp. tritici)

INSECT REACTION: moderately susceptible to sawfly

Origin & Breeding History: '5400IP' originated from the cross BW194//N93-0385/BW176 made by the breeder Joe A. Smith at Berthoud, Colorado in 1994. A modified pedigree breeding method using single seed descent was used to develop this variety. Individual head selections were made from an F2 population of this cross at AgriPro breeding nursery at Rosebank, Manitoba in 1995. Selections in the F2 were based on leaf rust resistance, height and maturity. Single seed descent was used to advance these selections throught the F3 and F4 generations in the greenhouse in Berhtoud, Colorado. In 1996, F5 headrows were individually bulked from a selection nursery in Rosebank, Manitoba. F5 selection criteria were height, maturity, and disease resistance to leaf rust, stem rust, tan spot and septoria leaf spots. The individual bulks (F6) were increased in an off-season nursery in New Zealand during 1996-1997. One of the selections was designated UGG97-2383 and tested in Proven Seed research plots from 1997 through to 2004. During those testing years '5400IP' was evaluated for yield, test weight, height, lodging, maturity, leaf rust, stem rust, foliar diseases, seed dormancy, kernel type and bread making quality. During 1998 to 2004, it also was grown in quality strips for industry evaluation. It was tested in the Central Bread Co-op as BW295 during 2001 and 2002 growing seasons. Sixty heads were picked for intitial purity from an F9 (F4 derived) increase plot at Berthoud, Colorado in 2001. It later became known as '5400IP'.

Tests & Trials: Tests and trials for '5400IP' were conducted during the summers of 2005 and 2006 at the Agricore United Research Farm in Rosebank, Manitoba. Plots consisted of 6 rows, 3 meters in length with a row spacing of 15 cm. There were 3 replicates arranged in a Random Complete Block Design.
