Özet:

 To identify oat genotypes suitable for Ispartas ecological conditions, a field experiment was conducted in 2022 and 2024 with 12 genotypes including different varieties, advanced generation lines, and local populations. The trial was established using a randomized block design with three replications. In the study, 8 kg of nitrogen and 5 kg of phosphorus were applied per decare, and 500 seeds were sown per square meter. In the study, panicle emergence time, number of panicles per square meter, plant height, panicle length, number of grains per panicle, grain yield, biological yield, and harvest index were examined. Based on two-year averages, all traits showed statistically significant differences among genotypes P0.01. Panicle number ranged from 349.17 to 540.83 m2, grain yield from 183.39 to 284.29 kg da¹, biological yield from 701.09 to 940.80 kg da¹, and harvest index from 25.60 to 31.52. Principal component analysis revealed considerable variation among genotypes, particularly in grain yield, biological yield, and harvest index. According to grain yield averages, YBDU-4, YBDU-9, Küçükyayla, YP-1, and Kahraman genotypes showed better adaptation to Isparta conditions. These genotypes may serve as potential genetic resources for breeding programs aiming to develop high-yielding oat varieties suitable for the region.

 Isparta koşullarına uygun yulaf genotiplerinin belirlenmesi amacıyla, 2022 ve 2024 yıllarında farklı çeşit, ileri generasyon hattı ve yerel popülasyonlardan oluşan 12 yulaf genotipinin yer aldığı bir deneme yürütülmüştür. Çalışma, Tesadüf Blokları Deneme Desenine göre 3 tekerrürlü olacak şekilde kurulmuştur. Araştırmada dekara 8 kg azot ve 5 kg fosfor uygulanmış, m²ye 500 adet tohum ekilmiştir. Araştırmada salkım çıkarma süresi, metrekaredeki salkım sayısı, bitki boyu, salkım uzunluğu, salkımda tane sayısı, tane verimi, biyolojik verim ve hasat indeksi özellikleri incelenmiştir. İki yıllık ortalamalara göre tüm özellikler yönünden genotipler arasında istatistiksel olarak önemli farklılıklar belirlenmiştir P0.01. İki yıllık ortalamaya göre metrekaredeki salkım sayısı 349.17540.83 adet, tane verimi 183.39284.29 kg da¹, biyolojik verim 701.09940.80 kg da¹ ve hasat indeksi 25.6031.52 arasında değişmiştir. Temel bileşenler analizi, özellikle tane verimi, biyolojik verim ve hasat indeksi bakımından genotipler arasında önemli varyasyonlar olduğunu ortaya koymuştur. Ortalama tane verim değerlerine göre YBDU-4, YBDU-9, Küçükyayla, YP-1 ve Kahraman genotiplerinin Isparta koşullarına daha iyi uyum sağladığı belirlenmiştir. Bu genotiplerin, bölgeye uygun yüksek verimli çeşitlerin geliştirilmesinde genetik kaynak olarak değerlendirilebileceği sonucuna varılmıştır.
