In 28 hybrids of F1 and F2 generations obtained from diallelic crossing 6 diversified lines were investigated. 15 features of crop structure were analysed and statistic variability factors, effect of heterosis, heritabilities and genetic advance were computed. Heritability estimates for individual features enabled identification of features: high values (52-60%) of height of the plant, compactness of ear and number of days from sowing to coming into ear; average values (38-45%) of width of flag leaf lamina, length of ear, number of spikelets in an ear and mass of 1000 grains; low values (19-25%) of average mass of grains from an ear, number of grains from an ear, mass of grains from the main ear, length and surface area of the flag leaf lamina, number of productive tillers in a plant, total number of tillers in a plant and mass of grains from a plant. The cultivation assessment of lines and hybrids was based on: arithmetic mean, heterosis effect, heritabilities and genetic advance
