The effect of genotype, seed category and year on yield components (number of spikelets per spike, grain number per spike, grain weight per spike and thousand grain weight) for three wheat genotypes were studied during a two-year research. Genotype PKB Lepoklasa and seed category pre-basic seed had the highest values for the largest number of the studied traits, while the genotype BG Merkur and the certified seed of the first generation had the lowest values. Higher values for the studied traits were found in 2010, compared to 2009. AMMI analysis established a significant effect of the interaction of factors and main components (PCA 1 and PCA 2) for all investigated traits except thousand grain weight. The genotype PKB Talas was the most stable, while the genotype PKB Lepoklasa was the least stable. Seed categories certified seed of the first generation and basic seed had similar reactions to the interaction between factors.
