Conteúdo: | The high cost of imported papaya seed in Brazil has motivated the conduction of the present study, which aimed at estimating heterosis effects and the indication of superior papaya hybrids, by means of a partial diallel scheme of eight genotypes from the groups 'Solo' and 'Formosa'. Parents and hybrids were evaluate in a randomized complete block design with four replications and 80 treatments (64 hybrids and 16 parents). Nine traits were evaluated and heterobeltiosis was verified for all traits. It was concluded that the diallel is a suitable strategy for the generation of papaya hybrids that meet national and international market standards. Superior hybrids with a view to further evaluation and cultivar release are those formed by the parents 'JS11' and JS 12' with parents: 'Sunrise Solo-TJ', 'Sunrise Solo-72/12-IS', 'Santa Bárbara', 'Baixinho de Santa Amália', 'São Mateus' and ' Sunrise Solo-783'.
