Book Description
Manitoba is a major producer of high quality oats (Avena sativa) destined for milling and food processing in domestic and export markets, particularly the United States. Strengthening the demand for Canadian oats requires continued improvement of oat cultivars to meet the changing needs of the agricultural and food industries. In order for plant breeders to achieve this, more information is needed regarding what factors affect variation in the milling, nutritional, functional and end-product quality of oats grown in western Canada. The objective of this study was to determine the relative effects of genotype, environment, nitrogen fertilization and their interactions on the quality of oats destined for human food. Replicated field tests were grown at each of six environments using a split plot design. Five genotypes were the main plots and four nitrogen fertilization treatments (0 to 120 kg/ha) were applied to the sub-plots. Hull content was significantly affected by a qualitative genotype-by-environment interaction, indicating the need for multiple testing sites. Growing conditions also had a strong influence on groat breakage, protein, and oil (36, 73, and 49 % of total variation respectively) but differences between genotypes remained consistent across environments. Genotype was the main factor affecting B-glucan content (78 % of total variation). Nitrogen fertilization had a greater impact on oat composition than on milling characteristics and in many cases the effect of nitrogen was dependant on the location. At sites where residual nitrogen was low (less than 36 kg/ha), fertilization resulted in increased levels of protein and B-glucan (by as much as 4.4% and 1% respectively), while oil decreased slightly (less than 1 %)...
