The phenotypic contributions of two individual Gossypium barbadense L. chromosomes in a G. hirsutum L. background were evaluated. Monosomes 6 and 17 of G. hirsutum were used to transfer the individual intact homologues from a G. barbadense line (3‐79) into G. hirsutum . Following transfer, backcross‐derived substitution lines with 25 pairs of G. hirsutum chromosomes and one pair of G. barbadense chromosomes (6 or 17) were evaluated for the following agronomic properties: date of first flower; earliness; yield; boll size; lint percent; lint index; seed index; fiber length; fiber coarseness; fiber strength; and fiber elongation. Significantly associated with substitution line 6 was later flowering, higher lint percent, and finer fibers. Short fiber length was significantly associated with substitution line 17. However, no characteristic feature of 3‐79 was associated with either substitution line.
