Variety Description

Varieties used for comparison: 'AC Crystal', 'AC Karma' and 'AC Vista'

Summary: The intensity of anthocyanin colouration of the coleoptiles in 'NRG010' is absent or very weak while it is weak to medium in 'AC Crystal' and 'AC Karma'. 'NRG010' has absent or very weak anthocyanin colouration of the flag leaf auricles while it is weak to medium in 'AC Crystal' and medium in 'AC Vista'. The plants of 'NRG010' are taller than the reference varieties. 'NRG010' has longer spikes than those of 'AC Crystal'. 'NRG010' has white kernels while those of 'AC Crystal' are red in colour.

Description:

PLANT: common spring type
SEEDLING (at four leaf stage): absent or very weak intensity of anthocyanin colouration of coleoptiles, weak pubescence on lower leaf sheath and blade

GROWTH HABIT (at 5-9 tiller stage): semi-erect to intermediate
FLAG LEAF (at booting): medium frequency of plants with recurved flag leaves, no anthocyanin colouration on auricles, medium glaucosity on sheath, weak pubescence on blade and sheath

SPIKE: parallel sided, medium density, medium to strong glaucosity, white in colour with predominantly inclined attitude at maturity
CULM: medium glaucosity, very weak curvature at maturity
STRAW: thin pith in cross section, weak anthocyanin colouration at maturity
AWNS: present, predominantly spreading attitude, white

LOWER GLUME: narrow to medium width, medium long, glabrous
LOWER GLUME SHOULDER: sloping, absent or very narrow width
LOWER GLUME BEAK: slightly curved, short length

KERNEL: hard white, large, ovate in shape, predominantly angular cheek, midlong to long brush hairs, midsize to large oval germ, midwide width with mid-deep crease

PERFORMANCE CHARACTERISTICS: good resistance to shattering, good resistance to drought

DISEASE REACTION: moderately susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species) and Loose smut (Ustilago tritici), resistant to Stem rust (Puccinia graminis f.sp. tritici), Common bunt (Tilletia caries Tilletia foetida) and Leaf rust (Puccinia triticina)

Origin & Breeding History: 'NRG010' (experimental designation 'GP010') is the result of the cross 'ND2710'/'HY459'//'AC Vista' made in 2001 at the Semiarid Prairie Agricultural Research Centre of Agriculture and Agri-Food Canada, Swift Current, Saskatchewan. F2 seed were inoculated with Common bunt and grown in a Leaf and Stem rust epiphytotic nursery in Saskatchewan. Disease-free, strong-stemmed and early maturing individuals were selected and designated as CO104S. A subset of F2 seed was grown in a Fusarium head blight nursery in Manitoba. Spikes with low incidence of Fusarium head blight were selected and designated as CO104P. In the F3 generation, seeds from CO104S and CO104P were grown in New Zealand and plants with shorter stronger stature were selected. In the F4 generation, seeds were inoculated with Common bunt and grown in a Leaf and Stem rust nursery in Saskatchewan. The F5 generation was grown in New Zealand in a plant progeny row nursery. In the F6 generation, subpopulations were grown in replicated trials in Saskatchewan and Manitoba. The F7 generation was grown in New Zealand. The experimental line CO104P-DG44 was identified based on response to Leaf and Stem rust, Fusarium head blight, Loose smut and Common bunt and on grain quality and kernel characteristics. The experimental line CO104P-DG44 was evaluated in the Western Hard White 'B' test in 2006 and as 'GP010' in the 2007 High Yield Wheat Cooperative test and in the 2008 General Purpose Cooperative test.

Tests & Trials: The trials of 'NRG010' (experimental designation 'GP010') were conducted during 2008 and 2009 at the Agriculture and Agri-food Canada Research Station, Swift Current, Saskatchewan. A 4 repetition randomised complete block design was planted with each replicate consisting of 4 rows, measuring 3 metres in length spaced 23 cm apart, and seeded at a rate of 220 seeds/square meter. Kernel characteristics were described by the Inspection Division, Canadian Grain Commission. 'NRG010' was also trialed and tested for agronomic characteristics, disease reaction, and end-use suitability in the Western Bread Wheat Cooperative Test 2006-2008.
