A two-year study was conducted on 16 wheat genotypes with the aim of examining the
reaction of genotypes to different environmental conditions. Grain weight per spike is a
quantitative trait, which phenotypic expression is determined by the influence of a number of
minor genes and environmental factors. Therefore, this trait is a suitable phenotypic marker of
influence of environmental factors on the plant. The year factor had the largest share in the
variation of grain weight per spike (67.82%), while the share of the genotype and the genotype x year interaction was significantly smaller (14.98 and 10.95% respectively). Drought conditions, which characterized the 2016/2017 growing season, affected the
reduction of grain weight per spike by 41.7%. The greatest reduction in the value of trait
under stress conditions was recorded in Fundulea 4 genotype (63.14%), which achieved the
highest value in favorable environmental conditions (3.5 g), while in drought conditions it had
a b...elow-average value (1.29 g). Also, Dunavka genotype made good use of favorable
environmental conditions to achieve a high value of grain weight per spike (3.14 g), so it can
be recommended for breeding in favorable climatic conditions. On the other hand, the highest
tolerance to drought was exhibited by the Pitoma genotype, which recorded a 15.67%
decrease in grain weight per spike. The high tolerance of the mentioned genotype results from
the highest value of the trait achieved in the dry growing season (1.83 g), which makes this
genotype a good genetic resource for breeding for drought tolerance.
