Abstract: The dependence of Brazil on imported improved papaya seeds was the main motivation for this research that primarily intended to evaluate the combining ability of eight genotypes from the 'Solo' group, crossed with eight genotypes from the 'Formosa' group following a partial diallel scheme. The traits mean fruit weight, brix degree and flavor revealed prevalence of additive effects in both genetic groups, while plant height was preponderantly additive only for the 'Solo' genotypes. On the other hand, the yield … Show more

“…Semelhantemente ao observado com os híbridos oriundos do cruzamento com o testador 1 ('JS-12'), houve baixa variação para esta característica (Tabela 4). Marin et al (2006) também encontraram baixa variação para este caráter, de -0,8 a 0,5 em híbridos de mamão obtidos de 'SS-72/12' ao avaliarem um conjunto de híbridos oriundos de um dialelo parcial.…”

“…Por outro lado, a linhagem L33 foi o único genótipo que apresentou valor médio inferior a 11,0 °Brix, com média igual a 9,9 °Brix, diferindo dos demais. Marin et al (2006) corroboram estes resultados, ao observarem variação de 7,85 a 12,65 °Brix na análise de híbridos de mamoeiro; Oliveira et al (2010) detectaram ampla variabilidade na análise de germoplasma, encontrando valores de 5,0 a 16,2 °Brix, e Dias et al (2011), avaliando 27 genótipos de mamoeiro, obtiveram médias de 7,25 a 11,53 °Brix.…”

“…However, Marin et al (2006a) evaluated different traits of papaya and reported low heterosis (2.79%) for traits such as cSS, as well as heterobeltiosis in some traits, in Formosa x Solo hybrids, though. otherwise, Marin et al (2006b) corroborated the possible exploitation of Formosa intragroup heterosis, and indicated the parent Maradol as a candidate. they also reported that good intragroup hybrid combinations can be achieved for Solo parents, but the genotypes used by the authors are not included in this analysis.…”

“…Papaya breeding is usually based on hybrids obtained between different heterotic groups (MaRiN et al, 2006b). two heterotic groups are reported in papaya, i.e., "Solo" and "Formosa", but the definition of the groups is based almost exclusively on the trait fruit weight, which is around 500 g per fruit for genotypes from the Solo group, and above 800 g per fruit for genotypes from the Formosa group.…”
