The aim of this study was to estimate the effects of the general and specific combining ability on the proportions of normal and deformed (carpelloid and pentandric) papaya fruits in hermaphrodite plants using mixed models. The ‘JS12-N’, ‘Waimanalo’ and ‘Golden’ parents showed the potential to decrease the number of deformed fruits. In contrast, the ‘Maradol x JS12-N’, ‘Maradol x Waimanalo’, ‘Maradol x Golden’, ‘JS12-N x JS12-4’, ‘JS12-N x Sekati’, ‘JS12-N x Waimanalo’, ‘Waimanalo x JS12-N’, ‘Waimanalo x JS12-4’, ‘Waimanalo x Golden’, ‘Waimanalo x Sunrise Solo 72/12’, ‘Golden x Maradol’, ‘Golden x JS12-N’, ‘Golden x Sekati’, ‘Golden x Waimanalo’ and ‘São Mateus x JS12-N’ hybrids have the potential to increase the number of marketable fruits while decreasing the number of carpelloid and pentandric fruits. Key words: Carica papaya, carpelloidy, pentandry, REML/BLUP. RESUMO - Alterações na forma dos frutos originários de flores hermafroditas são bastante comuns. Estas alterações são provocadas por anomalias florais. Este trabalho teve como objetivo obter via modelos mistos estimativas de capacidade geral e específica de combinação para proporção de frutos de mamoeiro normais e com deformidades: carpeloidia e pentandria, em plantas hermafroditas. Os genitores ‘JS12-N’, ‘Waimanalo’ e ‘Golden’ apresentam potencial para redução de frutos com deformidades. Os híbridos ‘Maradol x JS12-N’, ‘Maradol x Waimanalo’, ‘Maradol x Golden’, ‘JS 12-N x JS12-4’, ‘JS 12-N x Sekati’, ‘JS 12-N x Waimanalo’, ‘Waimanalo x JS12-N’, ‘Waimanalo x JS12-4’, ‘Waimanalo x Golden’, ‘Waimanalo x Sunrise Solo 72/12’, ‘Golden x Maradol’, ‘Golden x JS12-N’, ‘Golden x Sekati’, ‘Golden x Waimanalo’ e ‘São Mateus x JS12-N’ apresentaram potencial para aumento do número de frutos comerciais e redução de frutos carpelóides e pentândricos.
