Fitness and its components in Drosophila melanogaster were estimated under the homozygous condition. All of these parmeters, except for egg-to-adult viability and female fecundity, were measured under interspecific competition with D. hydei. The following results were obtained: (1) Significant genetic variation was detected in fitness, productivity, adult viability, total egg-to-adult viability and female fecundity. (2) Significant correlation was obtained between fitness and productivity (rp=0.792 for phenotypic correlation, rg=0.945 for genotypic correlation), between fitness and total egg-to-adult viability (rp = 0. 355, rg=0.395), and between fitness and female fecundity (rp=0.451, rg=0.511). (3) There was no significant correlation between total egg-to-adult viability and fecundity (rp= -0.046). The biological implications of the interrelationship between fitness and its components are discussed.
