Recurrent selection in papaya: An effective strategy for the continuous development of new cultivars

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