Abstract

The aim of the research was to determine the genetic variation for the spike production capacity in F3 generation, and the identification of genotypes with higher genetic production potential, which is one of the ways of development and selection of new wheat cultivars. Experimental formula was: (10G x 3R x 10 plants) = 300 spikes x 4 parameters = 1200 results. The range of genetic variation for the spike components was determined for: the number of grains per spike (NGS), the spike weight (SW) g spike-1, the grains weight per spike (GWS) g spike-1 and spikes harvest index (HI%), for the 10 genotypes in F3 - generation. The variation values for the spike components compared with the average effects of genes or (μF3) were NGSμ (±57.78%), SWμ (±59.80%), GWSμ (±63.27%) and spike HIμ (±19.79%). The genotype G-8/F3 is the most promising for the spike production capacity. The results of the research, identified the highly significant differences for spike components in the genotypes of F3 generation for the level of LSDp0.05 and LSDp = 0.01.
