Abstract

Besides high grain yield, some quality attributes are also desired in oat (Avena sativa L.) grains. The present study was conducted to investigate some physical and chemical characteristics of oat grains located at top, middle and bottom sections of the panicle. A total of twenty five different oat varieties commonly grown in various parts of the world were experimented in randomized blocks design with three replications in for two growing seasons in Samsun, Turkey. Panicles were divided into three groups as of top, middle and bottom. Some physical (thousand-grain weight, grain length and width, groat percentage) and chemical (ash ratio, protein ratio, starch ratio, fat ratio and fatty acids) characteristics of grains in different panicle groups were determined. Significant differences were observed in all quality parameters based on the position of grains within the panicle. Cultivars and cultivar x panicle interactions had significant effects on quality parameters. While higher thousand-grain weight, grain length and width, groat percentage, starch ratio, fat ratio, stearic and oleic acid contents were observed in top grains, higher ash ratio, palmitic and linoleic acid contents were observed in bottom grains.
