Papaya is a tropical fruit of high impact in Brazilian fruit crop. The main barriers to the expansion of the crop are reduced genetic variability and disease occurrence that results in the more expensive production. In this context it was made a cross between the genotypes ' JS12' and 'Golden' in the expectation of transferring the trait pale green peel of the fruit (Golden trait), associated as tolerant papaya skin freckles from the 'Golden' genitor to the 'JS12' genitor. The population BC1S1 was evaluated for its genetic variation between and within segregating progenies. Three individuals possessing the Golden characteristics (38BC1S1-11, 31BC1S1-10 and 30BC1S1-10-10) were selected. These progenies combine greater genomic proportion of the recurrent parent and good morphoagronomic attributes being the most suitable for the advancement of self pollination and backcrossing in papaya.
