Determination of forage yield and some plant characteristics of oat (Avena sativa L.) genotypes grown in different locations by biplot analysis

In this study, it was aimed to determine the forage yield of 10 oat cultivars and lines in Edirne, Biga and Tekirdağ locations, and to examine the hay yield with GGE Biplot technique. In terms of hay yield, the difference between cultivars in all locations was insignificant. In the second year of the study, the differences were found to be significant only in Edirne location. Hay yield was between 1.027.12 – 1.427.71 kg/da in the first year, 1.419.31 – 2.221.81 kg/da in the second year in Tekirdağ location, 1.417.00 – 1.726.00 kg/da in the first year, 1.239.75– 2.829.50 kg/da in the second year in Edirne location and it was 1.234.90 – 1.668.33 kg/da in the first year, 1.014.71 – 1.522.06 kg/da in the second year in Biga location. As a result, Sebat in Tekirdağ conditions, Kahraman and YBVD-24 in Edirne conditions, and Kahraman, Yeniçeri and YBVD-24 cultivars and lines in Biga conditions were determined as suitable in the cultivation of oats for hay production.
