Evaluation of Yellow Rust Reactions in some Bread and Durum Wheat Varieties by Using Spectral Band Regions

Yellow rust (caused by Puccinia striiformis f. sp. tritici) is an important fungal disease affecting wheat production and quality. The purpose of this study was to identify the spectral band regions that influence how changes throughout year determining plant responds yellow when it applied test materials at various doses (0%, 25%, 50%, 100%). Eser, Bayraktar 2000 Demir varieties showed high correlation in early-mid period for bread varieties, while Kenanbey variety exhibited mid-late period. Effective region all types are Red+Red Edge+ Near Infrared (NIR) range NIR both increase (+) severity values. Eminbey Çeşit-1252 durum displayed early period, followed Mirzabey medium Kızıltan-91 mid late Kızıltan 91 Edge+NIR region, Green+Red Green+Red+Red Edge were effective ranges reactions.
