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.

ÖzBu çalışma, 2014-2015 üretim sezonunda Kırklareli ve Edirne lokasyonlarında, altmış dört yulaf genotipin kullanıldığı denemede, dört adet standart çeşit (Kırklar, Kahraman, Yeniçeri ve Sebat) yer almıştır. Deneme Üçlü Alfa Latis Deneme Desenine (8 x 8=64) göre üç tekerrürlü olarak yürütülmüştür. Araştırmada, Trakya Tarımsal Araştırma Enstitüsü tarafından geliştirilen yulaf genotiplerinin tane verimi ve bazı kalite özellikleri incelenerek insan beslenmesi açısından bölgeye uygun genotiplerin belirlenmesi amaçlanmıştır. Bu kapsamda genotiplerin tane verimi ile kalite özelliklerinden bin tane ağırlığı, hektolitre ağırlığı, 2,2 mm elek üstü, kavuz oranı, tam tane yulafta protein, nişasta ve %β-glukan miktarları incelenmiştir. Araştırma sonucunda iki lokasyonda da tane verimi yönünden genotipler arasındaki fark istatistiki olarak önemli bulunmuştur. İncelenen kalite özellikleri yönünden genotipler arasında farklılıklar belirlenmiştir. Kırklareli lokasyonunda genotiplerin tane verimi; 369.7-865.0 (682.1) kg/da, bin tane ağırlığı 22.2-41.4 (31.6) g, hektolitre ağırlığı 48.2-58.6 (52.5) kg/hl, 2.2 mm elek üstü %20.0-96. AbstractThis study was carried out in 2014-2015 cropping year in Edirne and Kırklareli locations with 60 oat lines and 4 commercial varieties (Kırklar, Kahraman, Yeniçeri and Sebat). The experiment was established in an alpha lattice experimental design technique (8 x 8= 64) with three replications. In the research, it was aimed to determine genotypes of the region suitable for human nutrition by examining yield and some quality parameter performances of oat genotypes developed by Thrace Agricultural Research Institute. The traits such as grain yield (GY), thousand kernel weight (TKW), test weight (TW), plumpness (P, sieved 2.2 mm slotted), husk rate (HR), full grain oat protein (FGOP), starch (S), and β-glucan (β-G) content of genotypes were investigated. The variations among oat lines for grain yield was significant and differences for TKW, TW, P, HR, FGOP, S, and β-G were also determined. The GY, TKW, TW, P, HR, FGOP, S, and β-G of oat lines ranged between 369.7-865.0 (682.1) kg/da, 22
