F, and F, generations of four G. barbadense crosses studied for varaiablity in bol number per plant, yield of seed cotton, ginning percent and halo length showec that crosses B (Allepo x suvin) and D (Sudan G. 45 x Giza 7) registered high mean fo boll number, yield of seed cotton and ginning percent, while cross C (suvin x sujata, recorded high mean for mean halo-length. High mean variability for all the four traits were found in cross D. Transgressive segregation beyond the parental means was observed in F generation, indicating that commencement of selection in F, would be ideal, Positive deviates over the means of the respectiva sibs indicated that crosses E and D had relatively high potentiality as compared to other two crosses.
