Genetic-molecular characterization of backcross generations for sexual conversion in papaya (Carica papaya L.)

H. C. C. Ramos, Pereira, M. G., Pereira, T. N. S., Barros, G. B. A., and Ferreguetti, G. A., Genetic-molecular characterization of backcross generations for sexual conversion in papaya (Carica papaya L.), vol. 13, pp. 10367-10381, 2014.

The low number of improved cultivars limits the expansion of the papaya crop, particularly because of the time required for the development of new varieties using classical procedures. Molecular techniques associated with conventional procedures accelerate this process and allow targeted improvements. Thus, we used microsatellite markers to perform genetic-molecular characterization of papaya genotypes obtained from 3 backcross generations to monitor the inbreeding level and parental genome proportion in the evaluated genotypes.
