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: dateof 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.
