Özet

The aim of this study was to determine the adaptability and kernel quality of new maize hybrids in Bayramic-Canakkale ecological conditions (West part of Turkey). The field trials were carried out during the 2016 and 2017 planting seasons (spring) with 10 maize hybrids (A49, A9C1, A9C2, B4A, B4C, B4C2, B6C, BA, BC and BC2). Grain yields, some yield components and some grain quality characteristics (yield, protein content, total oil content and content of oleic acid, linoleic acid and linolenic acid) of hybrids maize were examined in this study. All kernel quality traits were mostly determined by the effect of the genotype. There were statistically significant differences among genotypes for all investigated agronomical and compositional quality traits. According to the results, significant differences were found between the genotypes and the years but the interaction of the two factors also had effect on all parameters. The hybrid named BC was outstanding compared to other hybrids for traits such as the thousand kernel weight, ear width, number of kernels per ear, first ear height and ear length. The BA hybrid had the highest values for plant height, day of silking and day of tasseling. In addition, there were positive and significant correlations between traits like ear width, number of kernels per ear and thousand kernel weight.
