"EARLY work on the performance of hybrid cottons was -*-' reviewed by Loden and Richmond (7) and by Fryxell. Some degree of heterosis for lint yield and other traits was found in most of the works reviewed, both in intraspecific and interspecific crosses. Fryxell et al. (2) have found that 17 of the 36 Gossypium hirsutum L. X G. barbadense L. crosses they evaluated yielded more than the better parent, but only a few of these crosses were better than the adapted check variety. Barries and Staten (1) reported a very high degree of heterosis for yield in the cross 'Pima 32' X 'Acala 1517C. The possibilities of practical utilization of hybrid cottons were discussed by Fryxell and Stroman (9).
