Abstract

This article presents an analysis of the results obtained on inheritance and variability of some morphoeconomic traits in F1-F2 descendants. Based on the results obtained, it was noted that in all F1 hybrid combinations, traits are inherited in intermediate, dominant and heterotic states. The average values of F2 hybrids were mainly within the parameters of the parent forms, while the inheritance of the trait acquired a polygenic character. Large-scale separation was observed according to some characteristics, and transgressive plants were isolated. As a result of research, salt-resistant, precocious, productive, large-flowered hybrids with high fiber yield and quality were created as starting materials for practical breeding.
