We present the objectives and methods of a project to evaluate the genetic variability and to do mass genotypic selection of ancient olive variety Cobrancosa. Field work is based on an experimental population containing 153 genotypes of Cobrancosa, sampled all over the region where it is grown. First experimental data on plant height and shoot diameter were collected and analysed in order to obtain broad sense heritability and coefficient of genotypic variation estimates. Based on those estimates we discuss intravarietal heterogeneity and genetic gains of yield and of quality characteristics to be obtained next years
