Decreasing of stem height gave higher possibility of efficient utilization mineral
elements for the head development. Also translocation of mineral elements is more
efficient in semidwarf cultivars from the vegetative organs to grain.
During investigated periods the highest average value of of thousand grain weight had
Partiyanka cultivar (x=41.47) the lowest average value of thousand grain weight
expressed KG-3062/1-93 cultivar (x=30.62) Table 2. Number of grain per spike and
thousand grain weight have strong influence on spike productivity. Yield of analyzed
wheat genotypes varied between 2875 kg ha -1 (KG-3419-3/97) and 4756 kg ha -1 (KG-
3625/97) Table 2. Yield is in high relationships with the number of stems per m 2 a nd the
percentage of fertile spikes, number of kernels per spike, thousand grain weight. The
genetic controls of stem height and other yield components are very important, but
environment has influence on expression of analyzed traits. Generally speaking,
genotypes reacted similarly to environmental variation for plant height, and number of
spikiest per spike, number of kernels per spike, thousand grain weight, differing in main
effect. On the contrary, genotype reaction for yield components in interaction making
phenotypic expression for those trait more unpredictable. The remobilization of reserve
into harvested organs varies among the cultivars. Yield is very important agroeconomic
traits which will in the focus of investigation in the future.
