Journal of Crop Production. 5:165-189. Interpretive Summary: Oats are a nutritious, high protein grain crop with important food, feed and value-added applications. For commercial purposes, oat quality is frequently expressed as a grade, based on test weight, foreign matter, and the physical appearance of the grain. More detailed quality analyses may include evaluations for percent groat, kernel size and uniformity, and groat composition. Compositional components of economic importance include protein, lipid, beta-glucan and antioxidant concentrations. Exact quality specification for quality requirements can vary widely among applications. Feed applications favor higher protein and fat concentrations, and lower fiber. Food applications favor lower fat concentrations, and higher beta-glucan. Production of high quality oat grain is dependent on the planting of high quality seed with current local adaptation, sound cultural practices, and favorable weather conditions. It is particularly important that seed planted produce plants resistant plant diseases. Disease infestation is a common source of quality loss. Unfavorable environmental conditions can also result in quality loss, but breeders continue to strive to create oat cultivars that will produce superior quality grain across diverse environments through genetic improvement of oats.

It is particularly important that seed planted produce plants resistant to current races of pathogens. Disease infestation is a common source of quality loss. Whereas, unfavorable environmental conditions can frequently result in quality loss, breeders continue to strive for environmental stability of quality traits through genetic improvement of oats. |
