Phenotypic and genetic correlations of quantitative traits were estimated in an auto sexing meat-type pigeon population. The pigeons were kept in pairs in a specially designed three tier cage system, in a windowless environmentaly controlled house at a constant 12 hour light period thro-ughout the year. For the estimation of correlations related to bodyweight at different ages, data of 220 sire-son and dam-daughter pairs were used. In the estimation of correlations related to production traits the data of 321 dam-daughter pairs were analysed. The phenotypic (rP) and genetic (rG) correlations between the traits studied were: 28 days body weight - adult body weight in males rP: 0.88, rG: 0.57, in females rP: 0.77, rG: 0.62, number of eggs produced per year - body weight at 28 days of age rP: -0.04, rG: -0.54, hatchability - number of eggs produced per year rP: 0.11, rG: 0.02, hatchability - number of squabs hatched per year rP: 0.78, rG: 0.17, hatchability - total weight of squabs produced per year rP: 0.74, rG: 0.17.
