Resumo: Abstract: Part of the success of a breeding program depends on the composition of the base population. Superior genotypes and unimproved dioecious varieties are sources of genes for traits of interest and excellent options for the formation of segregating populations. Here we describe the first cycle of recurrent selection (RS) in papaya and propose an effective strategy, unprecedented in the crop, to generate variability and new cultivars. Initially, the RS base population (UCP-C0) was developed with wide variability. Subsequently, 196 S1 progenies were obtained, evaluated in a trial, and the superior 40 S1 progenies were recombined. Among the traits of the selected progenies, high fruit yield (producing two to five fruits per axil) stands out. The S1 progenies were recombined and their seed bulk corresponds to the base population for the second cycle (UCP-C1). The results of the first cycle demonstrate the genetic potential of this population for the development of superior cultivars, and the breeding strategy applied is promising.
