Lukow, O. M., Adams, K., Suchy, J., DePauw, R. M. and Humphreys, G. 2013. The effect of the environment on the grain colour and quality of commercially grown Canada hard white spring wheat, Triticum aestivum L. ‘Snowbird’. Can. J. Plant Sci. 93: 1–11. One of the main advantages of hard white wheat is its lighter grain colour, which can produce visually appealing lighter-coloured end-products. However, grain colour variation can be a concern due to a lack of consistency. This study was carried out to determine the effect of the environment on commercially grown hard white wheat grain colour and wheat grading. More than 1100 samples of the cultivar Snowbird were collected from elevators across western Canada during the 2003 to 2007 crop years. Grain and wholemeal colours were recorded using the CIE L* a* b* scale. Samples were analyzed for grain properties including dimensions, hardness and protein content. Variation in grain colour was mostly attributed to annual fluctuations in climatic conditions (71–79%) and agro-climates (13–18%). Grain ranged in colour from white and bright to dark grey-red. Grain brightness was very highly correlated with grain yellowness. Grain a* and b* were inversely related to grade indicating that higher quality grain was redder and more yellow than lower grades. Warmer and drier environments showed reduced grain yields but produced on average better quality grain with higher protein content.

With the recent interest in genetically engineered (GE) wheat and the commercialization of novel-trait imidazolinone herbicide-resistant wheat in North America, volunteer wheat as a weed has also been the subject of renewed interest, specifically, its recruitment and persistence in annual cropping systems. The recruitment of seed from a wheat seedbank established the previous autumn was monitored in a flax crop at two field sites in southern Manitoba, Canada, in 2003 and 2004. Seeds of eight Canadian Western Hard Red spring wheat cultivars, which exhibit a range of preharvest sprouting-resistance characteristics, were broadcast and incorporated into the soil in the autumn at 500 seeds m−2. Tillage treatments consisted of autumn tillage only, and autumn and spring tillage. Recruitment the following spring occurred very early in terms of accumulated growing–degree days (base temperature of 0 C) but expressed as a proportion of total seeds broadcast was low and variable. Total cumulative emergence of wheat over all 4 site yr ranged from 0.9 to 13.1%, with an overall average of 4.3%. There was no relationship between preharvest sprouting-resistance characteristics and recruitment proportion, and no significant influence of tillage treatment on wheat recruitment. Wheat seed that did not recruit was rapidly degraded in the soil and did not persist for more than 12 mo. However, some emerged volunteer wheat plants escaped all control measures normally used in establishing and growing a typical flax crop, and these escaped volunteer wheat plants set viable seed. Therefore, results of this study indicate that efforts and attention should be directed toward achieving very high levels of volunteer wheat control in subsequent rotational crops and that reseeding by escaped volunteer wheat plants may be a more important persistence mechanism for spring wheat than multiyear soil seedbank persistence.

Preharvest Sprouting Resistance

Mature wheat (Triticum spp.) kernels subjected to high moisture often incur preharvest sprouting damage. The experiments described here sought to evaluate two methods of measuring preharvest sprouting susceptibility, and to determine the environmental sensitivity of the methods, for use in selection and testing of sprouting-resistant wheat genotypes. Preharvest sprouting of eight hexaploid wheat (Triticum aestivum L. em Thell) lines was measured by artificial wetting of intact spikes, and by germination tests on threshed seed from each of four location near Ithaca, N. Y., in 3 consecutive years. The relative size of genotypic and nongenetic effects varied over the course of the experiments. At optimal measurement times, genotype accounted for over 40% of phenotypic variation, with another 20% attributed to environment and interactions. Effects of nongenetic factors were minimal when phenotypes were based on germination percent at day 4 or spike sprouting score at day 6. A storage technique previously reported to preserve dormancy was found effective for up to 3 mo, increasing the number of treatments that can be tested at comparable levels of dormancy. These data will be useful in planning basic investigations of preharvest sprouting resistance, and incorporating sprouting resistance testing procedures into wheat breeding programs.Key words: Wheat, preharvest sprouting, resistance, germination, dormancy, white kernel color

KANE is a hard red spring wheat that meets the end-use quality and kernel visual distinguishability specifications of the Canada Western Red Spring market class. KANE was found to be adapted to the wheat-growing regions of Manitoba and eastern Saskatchewan from the data provided by the Central Bread Wheat Cooperative registration test in 2003–2005. In comparison with the check cultivars Katepwa, McKenzie, CDC Teal, AC Barrie, and Superb, the overall grain yield of KANE was similar to the high yield checks McKenzie and Superb. Compared with the highest yielding check McKenzie, KANE was 1.7 d later maturing, was 6 cm shorter, had stronger straw, and was significantly higher (1.1 kg hL-1) in test weight. KANE is resistant to the prevalent races of leaf rust and stem rust. Resistance to common bunt and loose smut was intermediate, being similar to CDC Teal and McKenzie, respectively. Resistance to fusarium head blight was similar to AC Barrie. KANE has good preharvest sprouting resistance with similar or lower sprouting scores compared to the best check in 4 out of 5 yr of testing. End-use quality tests showed that KANE had a 0.7% higher flour extraction rate than the best checks and was within the range of the checks for the other quality traits.
