Bingöl Koşullarında Hibrit Atdişi Mısır Çeşitlerinin Performansları

Araştırma 2014 ve 2015 yıllarında Türkiye’nin Doğu Anadolu Bölgesinde yer alan Bingöl şartlarında 25 atdişi hibrit mısır çeşidinin adaptasyon kapasitesini araştırmak ve incelenen özellikler arasındaki ilişkileri belirlemek amacıyla yürütülmüştür. Çalışma tesadüf blokları deneme desenine göre üç tekerrürlü olarak kurulmuştur. Araştırmanın sonuçlara göre her iki yılda da çeşitlerin verim ve verim özellikleri arasındaki farklar istatistiksel olarak önemli olmuştur. İncelenen verim özelliklerinin en yüksek ve en düşük değerleri çeşitlere ve yıllara göre değişmiştir. Mısır çeşitlerinin tane verimleri birinci yıl 552.13‐1044.20 kg/da, ikinci yıl 636.20‐1429.67 kg/da arasında değişmiştir. En yüksek tane verimi birinci yıl ADV‐2898 çeşidinde (1044.20 kg/da), ikinci yıl Tuano çeşidinde (1429.67 kg/da) belirlenmiştir. En düşük tane verimi ise birinci yıl Şafak çeşidinde (552.13 kg/da), ikinci yıl Dian çeşidinde (636.20 kg/da) kaydedilmiştir. Korelasyon analiz sonuçlarına göre, mısırda tane verimi ile koçan boyu, koçan çapı, koçanda tane sayısı, koçan ağırlığı ve 1000 tane ağırlığı arasında pozitif ve önemli ilişkiler belirlenmiştir. Tane verimi ile bitki boyu ve sap çapı arasındaki ilişki önemli çıkmamıştır.

Performances of Hybrid Dent Maize Cultivars in Bingöl Conditions

The research was conducted with aim to investigate adaptation capability of twenty five hybrid dent corn cultivars, and to determine relationships among traits in maize at Bingol, East Anatolia Region, conditions of Turkey during 2014 and 2015 growing seasons. The experiment was set up according to the Randomized Complete‐Block Design with three replicates. Results of the research showed that differences among the grain yields and yield components of cultivars were statistically significant in both years. The highest and the lowest value of yield components varied according to cultivars and years. The grain yield of maize cultivars varied in between 5521.3‐10442.0 kg ha‐1 in the first year and in between 6362.0‐14296.7 kg ha‐1 in the second year. The highest grain yields were determined in ADV‐2898 cultivar (10442.0 kg ha‐1) in the first year and Tuano cultivar (14296.7 kg ha‐1) in the second year. The lowest grain yield was identified in Şafak cultivar (5521.3 kg ha‐1) in the first year and Dian cultivar (6362.0 kg ha‐1) in the second year. According to correlation analysis, grain yield was positively and significantly correlated with ear length, ear diameter number of kernel per ear, ear weight and 1000 grain weight of maize. The non‐significant correlations were determined in between grain yield with plant height and stem diameter.
