Abstract
Four Gossypium barbadense L. and three G. hirsutum L. cotton varieties were crossed to obtain a set of diallel excluding reciprocals. Estima tes of general combining ability were highly significant for days to f irst flower, days to 50% flowering and days to bell opening, which dem onstrated the importance of additive genetic effects for these traits. The variances for specific combining ability were not significant for any of the traits. The implications of these findings on breeding pro cedures in cotton are discussed.
