GENETIC ANALYSIS OF STALK LENGTH IN DIALLEL CROSS BREEDING OF WINTER WHEAT
Abstract
The author explored variability and system of genetic parameters in determination of ear length in F1 hybrids of soft winter wheat on the basis of diallel crossbreeding. Diallel crossbreeding is considered to be the most general and most informative for genetic analysis of quantitative traits in plants. When doing such crossbreeding, the researcher is provided with the complete set of all gene combinations of forecrops. The researcher faces the difficulties in crossbreeding, but he receives the rich initial material for crop breeding. The article describes the material about 5 varieties and 1 line of domestic and foreign breeding and their diallel hybrids. The study was conducted in the field conditions of Siberian Research Institute of Agriculture in Omsk in 2013-2014. Winter wheat is a crop of high fertility; winter wheat can reveal its biological crop yield capacity when it is genetically protected from abiotic and biotic stressors and appropriate growing conditions. Genetic control of this feature is mainly determined by over domination and complementary epistasis. Its lability results in the fact that being influenced by environmental conditions it can change genetic formulas (set of genes) of the stalk length. The genetic control system of changes in the parameter is controlled by dominant genes. It certifies that selection of unique genotypes becomes difficult due to the change of meteorological factors combination. The author highlights that selection on the basis of “stalk length” should begin in later generations of hybrids (F4 – F6), when most genotypes go into a homozygous state. The author suggests to consider Splav variety in the humid conditions and Minskaya variety in dry conditions as a short - stemming donor.
