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.

Grain Colour

Association between protein content and a gene for grain colour in Triticum aestivum L. was studied using partially isogenic populations developed from F2 plants heterozygous for a locus controlling grain colour. The dominant allelomorph (R) was found to be associated with higher protein content. The cause of the association seemed to be due to linkage between this locus and genes controlling protein content.

AC2000 is a hard white spring wheat (Triticum aestivum L.) with resistance to preharvest sprouting and prevalent races of common bunt [Tilletia laevis Kuhn in Rabenh. and T. caries (DC.) Tul. & C. Tul.]. It is eligible for grades of the Canada Prairie Spring (White) wheat class.

Soft White Spring Wheat

Field experiments were conducted over four growing seasons in southern Alberta to develop improved irrigation and nitrogen fertilizer recommendations for soft white spring wheat (Triticum aestivum L.). Irrigation to provide available water in the root zone to maturity maintained acceptably low protein content of soft wheat fertilizer-N plus soil test NO3-N levels from 140 to 208 kg ha−1. Nitrogen fertilizer increased protein content in all 4 yr of the study and increased yields each year except 1981 when the soil contained a high level of NO3-N. The protein content was not raised above the level considered acceptable for the domestic Canadian market (10.5%, moist basis) unless fertilizer rates in excess of the economic optimum level were applied. Fertilizer-N response curves were developed for each cultivar, irrigation treatment, and year combination. These were used to show the relationship between yield and the level of fertilizer N plus soil NO3-N which would result in economic optimum yields of soft white spring wheat of acceptable protein content. The results suggest N rates can be increased about 30 kg ha−1 for each t ha−1 increase in the target yield of the producer.Key words: Wheat (soft white spring), Triticum aestivum L., irrigation, nitrogen fertilizer, protein, target yield

Preharvest Sprouting Resistance

White-seeded spring wheat germplasm line W98616 was selected for improved levels of preharvest sprouting resistance. W98616 has levels of seed dormancy comparable to Columbus, a red-seeded sprouting-resistant cultivar. W98616 has similar test weight, kernel weight, maturity, plant height, grain protein, and kernel hardness, but is lower yielding and 2 d later heading relative to BW264, a hard white wheat cultivar. Key words: Triticum aestivum L., germplasm, white spring wheat, preharvest sprouting resistance
