Özet
Bu çalışmada, farklı kökenli arpa (Hordeum vulgare L.) genotiplerinin sıcak ve kurak stresli yetiştirme sezonundaki performanslarının değerlendirilmesi amaçlanmıştır. Araştırma, 2020-2021 yetiştirme sezonunda Diyarbakır koşullarında yürütülmüştür. Toplamda 16 farklı arpa genotipi kullanılmıştır. Genotipler, morfolojik, fenolojik, agronomik ve kalite özellikleri açısından değerlendirilmiştir. Bulgular, incelenen özellikler yönünden genotipler arasında önemli farklılıkların olduğunu ortaya koymuştur. Özellikle, yerel çeşitlerin ticari çeşitlere göre daha yüksek verim ve kalite özelliklerine sahip olduğu tespit edilmiştir. Verim ve biyolojik verim, bitki boyu ve bin dane ağırlığı ile olumlu korelasyona sahiptir. Bu durum, bu iki özelliğin adaptasyon yeteneği yüksek olan arpa genotiplerinin belirlenmesinde kullanılabileceğini göstermektedir. Yüksek sıcaklık ve kuraklık tane verimini biyolojik verime göre daha fazla etkilemiş ve düşük hasat indeksi değerleri elde edilmiştir. Sonuçlar, yerel arpa çeşitlerinin modern çeşitlere göre avantajlı olduğunu ve ıslah çalışmalarında kullanımının faydalı olabileceğini ortaya koymuştur. Islah programlarında genel tane verimini artırmak için yüksek sıcaklıklara ve kuraklık koşullarına karşı daha toleranslı arpa genotipleri geliştirmeye odaklanılması gerekmektedir. Araştırma ayrıca, arpa üretiminde verimliliği ve sürdürülebilirliği en üst düzeye çıkarmak için tarımsal uygulamalarda yerel çeşitlerin kullanılmasının önemini ortaya koymaktadır.
Abstract The objective of this study was to assess the performance of barley (Hordeum vulgare L.) genotypes of diverse origins under conditions of drought and heat stress during a single growing season. The research was conducted at Diyarbakır condition, during the 2020-2021 growing season. A total of 16 different barley genotypes were employed. The genotypes were evaluated for morphological, phenological, agronomic and quality traits. The results demonstrated significant differences among the genotypes in terms of the examined traits. The range of variation for the barley genotypes examined were 57.0-131.3 kg/ha for grain yield, 859.6-1353.2 kg/ha for biological yield, 6.33-15.13.8 % for harvest index, 25.6-35.3 g for thousand grain weight and 13.05-15.82 % for protein content. Among the barley genotypes used, Keçiburcu registered variety was the earliest and had the highest grain yield. It was determined that the local varieties used in the study had higher yield and quality characteristics than the registered varieties. Among the traits examined, plant height and thousand grain weight were found to have positive and significant correlation with grain yield and biological yield at 5% level. This indicates that these two traits can be used to determine barley genotypes with high adaptability. The results showed that high temperatures and droughts had a greater impact on grain yield than biological yield, resulting in low harvest index values. The results revealed that local barley cultivars have advantages over modern cultivars and can be used as a gene source in breeding studies. Furthermore, the study suggested that breeding programs should focus on developing barley genotypes with increased tolerance to high temperatures and drought conditions in order to improve grain yield. Additionally, the research highlighted the importance of utilizing local cultivars in agricultural practices to maximize productivity and sustainability in barley production.
