In the article described the results of the analysis of the dominancy and variability of the main components of early maturing, i.e. the “germination-50% flowering” and the “germination-50% maturing” periods of F1-F4 hybrids developed by the participation of the introgressive cotton progenies. As result of investigations there are found out mainly negative heterosis, full dominance and intermediate inheritance, i.e. early maturing occur for the “germination 50% flowering” and “germination-50% maturing” periods at hybrids developed by the participation of introgressive cotton progenies. It was concluded possibility of using of them in the breeding of F1 hybrids with high heterosis. The cotton progenies PL-4684-86/16 of; PL-470/1/16; PL-58/16 and PL-588/16 and hybrid combinations PL-4679-81/16 x Jarkurgan; PL-58/16 x Jarkurgan; PL-200/16 x Jarkurgan; PL-4747-48/16 x Jarqurgan and PLBSG/16 x Jarqurgan developed through introgressive selection method were recommended to be widely used in studies on improvement of early maturity.
