Bu çalışmada; Orta Anadolu Bölgesi kuru koşullarda 10 arpa çeşidinin (Tarm 92, İnce 04, Karatay 94, Yalın, Çetin 2000, Osvit, Mizgin, Yüksel, Keykubad ve Misket) tane verimi bakımından, GGE-biplot analiz yöntemi ile stabilitelerinin belirlenmesi amaçlanmıştır. Denemeler; 2018-2019 yetiştirme döneminde Eskişehir, Konya, Ankara (Haymana ve Yenikent) lokasyonlarında, tesadüf blokları deneme desenine göre yürütülmüştür. Denemelerde 2 sıralı (Hordeum vulgare conv. distichon), 6 sıralı (Hordeum vulgare conv. hexastichon) ve çıplak taneli arpa (Hordeum vulgare var. nudum Hook. f.) genotipleri kullanılmıştır. Tane verimine ilişkin varyans analiz sonuçlarına göre genotip (G), çevre (E) ve genotip × çevre interaksiyonu (GEI) istatistiki olarak önemli (p<0.01) bulunmuştur. Çeşitler tane veriminde 441.0-587.2 kg da-1 arasında ortalama değerler göstermiştir. Tane verimine ait verilere uygulanan GGE-biplot analizinde varyasyonun %66.25’i PC1’de, %25.05’i PC2’de dağılım göstermiştir. Deneme çevreleri 2 mega-çevre oluşturmuştur. Ortalama çevre eksenine (AEC) göre yapılan değerlendirmede; 2020 yılında tescil edilen Keykubad, Mizgin, Yüksel ve Misket AEC ordinatının ilerisinde yer almışlardır. İki sıralı arpa çeşidi Keykubad en yüksek PC1 değerine sahip olup, en yüksek performansı göstermesi yanında, en stabil çeşit olarak belirlenmiştir. Çıplak taneli çeşitlerden Yalın ve Osvit AEC ordinatının gerisinde yer almalarına karşın, Yalın AEC apsisine daha yakın konumu ile daha kararlı bir yapı göstermiştir. Altı sıralı çeşitlerden Mizgin ise Çetin 2000’e göre AEC ordinatının oldukça üzerinde yer alarak daha stabil bir görünüme sahiptir. 2020 yılında tescil edilmiş arpa çeşitleri olan Keykubad, Mizgin, Yüksel, Misket ve Osvit’in tane verimi bakımından standart çeşitlere eşdeğer ve üstün özelliklere sahip oldukları belirlenmiştir.
In this study, the aim of the Central Anatolian Region is to determine its stability with the GGE-biplot analysis method in terms of productivity of 10 arpa varieties (Tarm 92, Ince 04, Karatay 94, Yalın, Çetin 2000, Osvit, Mizgin, Yüksel, Keykubad and Misket). Tests; in the 2018-2019 training period in Eskişehir, Konya, Ankara (Haymana and Yenikent) locations, random blocks have been carried out according to the test pattern. 2 in the trials (Hordeum vulgare conv. Hordeum vulgare conv (Hordeum vulgare conv. There are hexastichon) and naked taned arpa (Hordeum vulgare. The Nudum Hook. Genotypes are used. According to the variance analysis of the yield, the genotype (G), the environment (E) and the genotype × environmental interaction (GEI) were statistically important (p<0.01). The varieties showed average values between 441.0-587.2 kg and 1 in one production. In the GGE-biplot analysis, which applied to data related to the yield, 66.25% of variations were distributed in PC1 and 25.05% in PC2. The experimental environments have created 2 mega-environments. According to the average environmental axis (AEC), they were ranked ahead of the Keykubad, Mizgin, Yüksel and Misket AEC order, which was registered in 2020. The two-arranged arpa variety Keykubad has the highest PC1 value, and, in addition to its highest performance, is determined as the most stable variety. Although the naked dwarf varieties are behind the Yalin and Osvit AEC ordinances, Yalin has shown a more stable structure with its location closer to the AEC axis. Mizgin, of the six consecutive varieties, has a more stable appearance, ranging quite above the AEC order, compared to the 2000 hard. In 2020, the registered arpa varieties of Keykubad, Mizgin, Yüksel, Misket and Osvit are determined to have equivalent and superior characteristics to the standard varieties in terms of productivity.
In this study, it was aimed to determine the stability of 10 barley varieties (Tarm 92, Ince 04, Karatay 94, Yalin, Cetin 2000, Osvit, Mizgin, Yuksel, Keykubad and Misket) in dry conditions in the Central Anatolia Region in terms of grain yield by using GGE-biplot analysis method. The trials were carried out according to the randomized block trial design in 4 locations (Eskisehir, Konya, Yenikent and Haymana of Ankara) during the 2018-2019 growing season. Two-rowed barley (Hordeum vulgare conv. distichon), 6-rowed barley (Hordeum vulgare conv. hexastichon) and hulless barley (Hordeum vulgare var. nudum Hook. f.) genotypes were used in the experiments. According to the results of variance analysis related to grain yield, genotype (G), environment (E) and genotype × environment interaction (GEI) were found to be statistically significant (p<0.01). Cultivars showed average grain yield values between 441.0-587.2 kg da-1. In the GGE-biplot analysis applied to the grain yield data, 66.25% of the variation was distributed on PC1 and 25.05% on PC2. Trial environments created 2 mega-environments. In the evaluation according to the average environment coordinate (AEC); Keykubad, Mizgin, Yuksel and Misket, registered in 2020, were placed beyond the AEC ordinate. Two-row barley cultivar Keykubad has the highest PC1 value and has been determined as the most stable variety besides showing the highest performance. Although Yalin and Osvit cultivars of hulless barley are located behind the AEC ordinate, Yalin showed a more stable structure with its position closer to the AEC apsis. Mizgin, one of the six-row cultivars, has a more stable appearance by being well above the AEC ordinate compared to Cetin 2000. It was determined that Keykubad, Mizgin, Yuksel, Misket and Osvit, which are registered barley cultivars in 2020, have equivalent and superior characteristics to standard cultivars in terms of grain yield.
