Genetic and ecological bases of KBGU breeding lines and hybrids

The creation of maize lines and hybrids requires a clearer and in-depth analysis of environmental factors affecting the phenotypic manifestations of the main economically valuable traits within the framework of the "interaction of genotype-limiting environmental factors" system. The role of the environment in this system becomes especially important in connection with climate change, the decrease (or increase) of stress factors and the shift of their manifestation by phases of development. Using the example of self-pollinated maize lines and hybrids of KBGU selection, the correlation between the main environmental bonds, the mean squares of the ACS and the SCS by their ratio, as well as the main parameters of the genetic determination of the trait is determined.
