Studies to assess the breeding samples of soft winter wheat by weight of grain from
the main ear anddetermine the indicators of adaptability were conducted at the Bila Tserkva
Research and Selection Station (BTRSS) in 2011–2013. The study revealed significant
differences in breeding lines in the range of variability of grain mass from the main ear and
identified small, medium and significantcoefficients of variation, which indicates their excellent
response to environmental conditions. It was due to genotype, year conditions and their
interaction. Line 42 KS had significantly higher than the standard grain weight of the main ear
(0.14 g) and the lowest value of the coefficient of variation (8.7%). According to the indicators of
adaptability(GAC, σ²(GxE)gi, σ²SACi, σSACi, etc.) the lines 42 KS, 24 KS and 44 KS were
distinguished. There was asignificant correlation between the weight of grain from the ear and
the weight of 1,000 grains (0.603–0.674) and the direct influence of the weight of grain from the
main ear on the weight of grain from the plantand grain yield (0.805–0.942). Selected lines as a
result of research (2015–2020) from these populations of soft winter wheat are competitively
tested in the conditions of Bila Tserkva Research and Selection Station, forming high grain yields
(7.39–8.12 t ha-1
) and will be transferred to 2021 for the State variety test for inclusion in the
Register of plant varieties suitable for distribution in Ukraine.
