Grain yield and some quality traits of naked oat cultivars

33949

Oat cultivars should have both high yield potential and some quality criteria in accordance with using targets. Therefore, grain yield and quality traits of eight naked oat cultivars grown at three locations were studied. This study was carried out during the 2007-2008 and 2008-2009 growing seasons in Samsun-Kurupelit and Bafra locations. Grain yield, hectoliter weight, thousand grain weight, grain composition(protein, fat, β-glucan, starch, fatty acid, K, Ca, P and Mg) were evaluated. Analysis of the combined datafor all locations showed significant genotypic differences for all traits except starch. Also, the cultivar × location interaction was significant for all traits. On average, among the cultivars, grain yield varied from2106.6 (Eva 1) to 3891.9 (AC Belmont) kg ha^-1, hectoliter weight from 52.3 (Lisbeth) to 60.8 (Eva 1) kg,thousand grain weight from 20.1 (Lisbeth) to 26.6 (Eva 1) g, protein content from 12.3 (AC Belmont) to15.3% (CROA 60), the starch content ranged from 57.5 (AC Belmont) to 60.2% (Eva 1), β-glucan content from 4.1 (AC Belmont) to 4.8% (CROA 60) and fat concentration from 5.0 (Eva 1) to 7.7% (Mozart). Small but significant differences in fatty acid composition were found between the naked oat cultivarsstudied. The results showed that the predominant component of the studied naked oat grain fat was oleicacid (35.7-42.2%), linoleic acid (35.5-40.5%) and palmitic acid (16.2-17.2%). Owing to high nutritive values, oat should be recommended to use in human diets.
