Abstract :

The research was conducted with aim to investigate adaptation capability oftwenty five hybrid dent corn cultivars, and to determine relationships among traits inmaize at Bingol, East Anatolia Region, conditions of Turkey during 2014 and 2015 growingseasons. The experiment was set up according to the Randomized Complete‐Block Designwith three replicates. Results of the research showed that differences among the grainyields and yield components of cultivars were statistically significant in both years. Thehighest 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 yearand in between 6362.0‐14296.7 kg ha‐1 in the second year. The highest grain yields weredetermined 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 correlatedwith ear length, ear diameter number of kernel per ear, ear weight and 1000 grain weightof maize. The non‐significant correlations were determined in between grain yield withplant height and stem diameter.
