Genotype selection is a key requirement for high yields in wheat crop management; higher yields can only be realized with good genetic potential. The performance of different varieties is also influenced by the environment, and it is important to understand that no genotype is perfect in all growing areas. To assess the behavior of 24 winter wheat genotypes regarding their germination energy, germination capacity, thousand kernel weight, grain yield, grain protein content and test weight, a study was conducted over two consecutive growing seasons at ARDS Turda, under two different amount of nitrogen fertilizer applied, and it has been investigated whether there is any connection between each of these traits. The experimental factors and their interactions had a different influence on the studied traits. The growing season and the nitrogen fertilization had a highly significant effect on yield, protein content and test weight. The genotype had a highly significant effect on all the studied traits. Thousand kernel weight in comparison with the other traits studied was strongly influenced by the genotype and less by the growing season and nitrogen fertilization.
