Özet:

In this study, 251 oat populations and 4 oat cultivars collected from 10 provinces (Düzce, Bolu, Zonguldak, Karabük, Kastamonu, Ordu, Sinop, Samsun, Amasya ve Tokat) in the Central and Western Black Sea region were used. According to the results of the two-year, it was determined that there were significant differences between years and genotypes in terms of all characteristics examined. Year × genotype interaction was found to be significant only for the number of spikelet per panicle, the number of kernels per panicle, kernel weight per panicle, kernel length and groat percentage. In the study, a large variation was determined among genotypes in terms of characteristics examined, and the panicle length ranged from 21.27 to 37.70 cm, number of spikelet per panicle from 26.08 to 75.35 pieces, number of kernel per spikelet from 1.64 to 2.43 pieces, number of kernel per panicle from 51.54 to 155.00 pieces, kernel weight per panicle from 1.44 to 4.85 g, thousand-kernel weight from 18.55 to 38.41 g, kernel length from 9.81 to 15.72 mm, kernel width from 1.96 to 2.94 mm, groat percentage 51.85 to 77.78 % and glume length from 18.12 to 29.76 mm.
