In this paper presents data of researches about fiber length in the 4-5 species. The largest number of plants with the indicated analyzed trait in hybrid combinations, obtained with the participation of the Omad variety, appeared with a number of variations in fiber length at 35.0-36.0 mm and above. Investigation of 4-species hybrids of F2 and back cross hybridization allowed some improvement in the average value of trait when compared with F1. Despite the emergence of transgressive plants with fiber length 36.1-37.0 mm and above, the average trait of composite 5 species hybrids F2 remained almost at the level of …
