Abstract

Annotation: The article presents the results of a study of the crossing ability of cotton varieties in terms of yield in 2019-2021. At the
same time, on average, high yields were observed in the varieties "Sultan", "S-7300", "Ilgar" from maternal forms, as well as
"UzPITI-202", "Andijan-36", "UzPITI-201" varieties from paternal forms. The efficiency of general crossability (OCS) was noted
among the maternal forms in the varieties "Sultan" and "Ilgar", and among the paternal forms in the variety "UzPITI-202".
In other varieties, the efficiency of ACS is unstable over the years, showing an inefficient indicator based on the average annual
indicator.
In terms of productivity, it was found that the overall crossability of the varieties "Sultan", "Ilgar" and "UzPITI-202" is high.These
varieties are recommended as primary material for cotton breeding.
