ÖzBu çalışma, Trakya Tarımsal Araştırma Enstitüsünün ıslah çalışmaları sonucu geliştirilen yulaf genotiplerinin tane verimi, bazı kalite ve tarımsal özelliklerinin belirlenmesi amacıyla [2012][2013] This study was carried out at Edirne in 2012-2013 and at Edirne and Kırklareli locations in 2013-2014. Sixteen oat genotypes, and five standard varieties (Checota, Kırklar, Kahraman, Sebat and Y-330) were planted as research materials. It was aimed to determine grain yield, quality characteristics and agronomic traits of some oat genotypes developed by Thrace Agricultural Research Institute. This study was conducted in randomized complete block design technique with four replicates. The traits such as grain yield, plant height, ripening period and thousand grain weight, test weight, protein ratio, groat percentage, husk rate and kernel plumpness (P. sieved 2.2 mm slotted) quality parameter performances of genotypes were investigated. The variations among oat lines and locations for investigated properties were significant. The grain yield, plant height, ripening period, thousand grain weight, test weight, protein percent age, groat percent age, husk rate and kernel plumpness (P. sieved 2.2 mm slotted) of oat lines ranged between; 281. 4-688.3, 349.1-828.0 and 478.2-993.0 kg/da, 110.8-156.0, 141.3-177.5 and 126.3-171.3 cm, 29-37, 33-39 and 36-43 day, 18.7-31.6, 19.6-38.7 and 22.7-45.0 g, 43.9-55.5, 45.7-60.4 and 44.0-60.7 kg/hl, 12.7-15.2, 10.9-14.3 and 9.0-11.3%, 56.1-75.5, 62.5-77.7 and 61.5-78.4%, 24.5-43.6, 20.0-37.3 and 21.6-38.2%, 25.1-81.9, 17.3-93.7% and 28.3-95.5% at Edirne in 2012-13 and at Edirne and Kırklareli Locations in 2013-14 respectively. The oat line 10 had the highest mean grain yield with 734.8 kg/da and followed by oat line 7 with 728.1 kg/da and oat line 15 with 695.6 kg/da in terms of grain yield in all locations. In the control varieties, Kırklar variety had the highest grain yield with 690.2 kg/da followed by Kahraman variety with 686.3 kg/da while the lowest grain yield was obtained from the Y-330 variety with 372.1 kg/da and Checota variety with 397.0 kg/da. Short oat line 15, having short plant height and lodging resistance registered as a cultivar candidate to the Seed Registration and Certification Institution. Height and lodging resistance of oat line 15 was offered to registration in 2014.
