Variability of spike productivity in F2 hybrids obtained by crossing common wheat varieties Novosibirskaya 67, Saratovskaya 29, and Puza-4 with the Skle 123-09 multifloret line

Popis výsledku v původním jazyce

Parameters of spike productivity indices were evaluated in plants of F2 populations obtained by crossing the Novosibirskaya 67, Saratovskaya 29, and Puza-4 varieties with the Skle 123-09 line, characterized by "ultifloret". It is shown that the line Skle 123-09 differed significantly from the studied cultivars in spike density, but no significant differences were found in spike length or the number of spikelets. Two-way analysis of variance in F2 hybrids showed that the variability of the spike length was contributed mainly by the genotypic environment and the interaction of the factors "genotype x environment". The variability of the number of spikelet in spike was determined mainly by environmental conditions. This was particularly true for cultivars Saratovskaya 29 and Puza-4, which were created for the cultivation in arid regions. The variability of the resulting character "spike density" was affected by environmental conditions, genotype, and the "genotype x environment" interaction. Examination of the F2 populations revealed plants with fan-shaped spikelets; high grain content, as in Skle 123-09; and the best performance of other spike characters. The selected plants will be used to fix the multifloret character in the parental varieties.
