Variety Description

Varieties used for comparison: 'AC Barrie', 'AC Elsa', 'Infinity' and 'AC Intrepid'

Summary: 'Goodeve' has a more erect growth habit at the 5-9 tiller stage than 'AC Barrie' and 'Infinity'. The flag leaf of 'Goodeve' is wider and less waxy than in 'AC Intrepid'. 'Goodeve' heads earlier than 'AC Barrie', 'AC Elsa' and 'Infinity' and matures earlier than 'AC Barrie'. 'Goodeve' is shorter than 'Infinity'. The glaucosity of the neck of the culm of 'Goodeve' is stronger than 'AC Elsa' and 'Infinity'. 'Goodeve' has a waxier spike than 'AC Elsa'. The spike of 'Goodeve' is slightly shorter than 'Infinity'. 'Goodeve' has a narrower glume than 'Infinity' with a narrower shoulder than 'AC Barrie', 'AC Elsa', 'Infinity' and 'AC Intrepid'. 'Goodeve' carries the Sm1 gene for resistance to orange wheat blossom midge while the reference varieties do not.


PLANT: spring type, semi-erect growth habit
SEEDLING: weak to medium anthocyanin colouration of the coleoptile, weak pubescence on lower leaf sheaths, weak pubescence on lower leaf blades at the 4 leaf stage

FLAG LEAF: medium to high frequency of plants with recurved/drooping flag leaves, very weak to weak pubescence on the blades and sheaths, absent or very weak intensity of anthocyanin colouration of auricles, medium glaucosity of sheath

CULM NECK: medium to strong glaucosity, very weak to weak curvature
STRAW: thin, very weak to weak anthocyanin colouration at maturity

SPIKE: parallel-sided shape, medium density, erect to inclined at maturity, medium to strong glaucosity, white at maturity, awnlets present
LOWER GLUME: narrow to medium width, long to very long length, absent or very weak pubescence, sloping to straight very narrow to narrow shoulder, straight short beak

KERNEL: hard red type, medium red colour, small to medium size kernel, oval shape, angular cheek shape, midlong brush hairs, midsize germ, round shape of germ, mid-wide to wide crease, shallow to mid-deep crease

AGRONOMIC CHARACTERISTICS: good resistance to shattering, good tolerance to drought, good resistance to pre harvest sprouting, good bread quality, moderately susceptible to susceptible to Fusarium head blight (Fusarium graminearum, Fusarium species), susceptible to Common bunt (Tilletia caries, Tilletia foetida), resistant to Loose smut (Ustilago tritici), moderately resistant to Leaf rust (Puccinia triticina), resistant to Stem rust (Puccinia graminis f.s.p. tritici) and resistant to orange wheat blossom midge (Sitodiplosis mosellana).

Origin & Breeding History: 'Goodeve' (previously known as BW841) derives from the cross 94B43-BLW4 / AC Intrepid made in 1998 at the Agricuture & Agri-Food Canada Cereal Research Centre, Winnipeg, Manitoba. 94B43-BLW4 = BW174*2 / Clark, in which Clark is the source of the resistance to the orange wheat blossom midge. Four subpopulations were created having sprouting resistance. Shorter, stronger-stemmed rust resistant plants were selected and threshed as a bulk. 2000 F3 seeds of each subpopulation were planted near Lincoln, New Zealand. Disease free, shorter, stronger-stemmed F3 plants were selected and threshed as a bulk. Bulk F4 seed from each population was inoculated with common bunt and space planted in a leaf and stem rust epiphytotic nursery near Swift Current, Saskatchewan. About 200 disease free, strong-stemmed and early maturing plants were selected from each population, threshed and selected for kernel characteristics. Of these, 125, 92, 149 and 95 selections were tested and selected for midge resistance. In the F5 generation 86, 65, 93 and 55 lines from the four subpopulations were grown in a plant progeny row nursery near Lincoln, New Zealand. In the F6 generation 34, 27, 26 and 18 lines were grown near Swift Current, Saskatchewan to assess agronomic traits and and response to leaf and stem rust. In the F7 generation 4, 4, 7 and 3 families (3 to 5 lines per family) were grown out near Irwell, New Zealand. In the F8 generation, 7 lines from 2 families were grown in replicated trials near Swift Current and Indian Head, Saskatchewan. Reaction to leaf and stem rust was assessed near Glenlea, Manitoba. Selected lines were screened for reaction to loose smut, common bunt and the absence of the band (susceptibility to orange wheat blossom midge) linked to the marker WM1F3/WM1R214. The experimental line B9818B-323C was selected and further tested in the Western Bread Wheat 'A_4' test in 2003 and in the Western Bread Wheat Cooperative Trial as BW841 from 2004 to 2006.

Tests & Trials: Tests and trials were conducted during the summers of 2006 and 2007 at the Agriculture & Agri-Food Canada Research Station, Swift Current, Saskatchewan. Plots consisted of 4 rows, with a row length of 3 metres and a row spacing of 23 cm. There were 4 replications arranged in randomized complete block design.
