Wheat production is under pressure due to climate change, increasing input production and higher demand for grain. Successful production depends on certain factors such as agroecological conditions, technical management and genotype, i.e., variety. The main goal was to determine yield, yield components and other morphological and agronomic characteristics of different wheat varieties and to analyze weather conditions during the 2020/2021 vegetative season. The research was conducted on agricultural holding in eastern Croatia according to RCB design in three replications. In general, the weather during 2020/2021 did not deviate too much compared to the observed long-term mean, but significant deviations in distribution were recorded during individual months. The precipitation deviation ranged from -99.7 % (June) to + 51.0 % (December), while air temperature oscillations were even more pronounced. The implemented agrotechnics were in accordance with the profession's recommendations for adequate plant protection and mineral fertilization. The analysis of variance revealed significance for five out of nine properties studied (number of grains per ear, 1000 grain mass, hectolitre mass, plant height and ear length). The average yield of all five varieties in this survey was 9.36 t ha-1. Each variety had certain advantages in terms of one and/or more characteristics, as the yield differences were not statistically justified. By sowing high yield varieties of different seed companies, it is possible to achieve higher and more stable yields, which is the goal of every production. Choosing the right varieties of wheat for a particular area is also important due to the increasingly pronounced climate changes.
