“…Variações em características visuais e organolépticas do mamão podem ocorrer em função de diferenciações entre grupos da espécie, suas variedades e cultivares (FAO, 2003). No Brasil, as principais variedades e cultivares híbridas são dos grupos Solo e Formosa (Vivas et al, 2017;Carvalho et al, 2020). No grupo Solo encontra-se a maioria das cultivares de mamoeiros utilizadas no Brasil e no mundo, este grupo apresenta frutos pequenos, com peso de 350 a 600 g e de polpa avermelhada.…”

“…A percepção de novos cenários industriais e econômicos a serem explorados pelo Brasil, desperta a necessidade de compreender o perfil da produção de mamão no país, especialmente as suas atuais limitações. No Brasil, a produção comercial de mamão concentra-se principalmente nas Regiões Nordeste e Sudeste (EMBRAPA, 2019; IBGE, 2021) e é dependente de poucas cultivares híbridas de genótipos dos grupos Solo e Formosa, o que implica na baixa diversidade genética das plantas (Vivas et al, 2017;Carvalho et al, 2020). Esta baixa variabilidade genética está sujeita aos efeitos das condições edafoclimáticas e à incidência de pragas e doenças fúngicas e virais, fatores que afetam qualitativamente e quantitativamente a produção de mamão no país (Souza Júnior, Nickel & Gonsalves, 2005;EMBRAPA, 2013;Vivas et al, 2017;Carvalho et al, 2020).…”

O Brasil está entre os principais países produtores e exportadores de mamão (Carica papaya Linnaeus). O mamão é um dos frutos mais importantes na economia e alimentação brasileira, com inúmeras possibilidades industriais e de aplicações nutricionais, farmacológicas e medicinais. Contudo, sua produção no país apresenta aspectos particulares, os quais influenciam as pesquisas científicas sobre o fruto, bem como o mercado consumidor nacional e mundial. Este estudo consiste de uma revisão bibliográfica sobre aspectos e peculiaridades da produção de mamão no Brasil. Foi incluído um breve histórico do mamão; características gerais da planta mamoeiro e do fruto mamão; características de consumo e aplicabilidades industriais do fruto; produção comercial no Brasil; principais cultivares híbridas utilizadas e fatores de risco para a produção, especialmente doenças virais de impacto econômico; aspectos do melhoramento genético do mamoeiro no Brasil; as limitações da transgenia no país e novas estratégias sugeridas. A partir do conjunto de informações deste estudo, são consideradas necessárias pesquisas aplicadas sobre novas tecnologias para a manutenção da produtividade do mamão no Brasil. Para tanto, sugere-se a realização de pesquisas genéticas sobre a hibridização das cultivares comerciais utilizadas com variedades selvagens de mamoeiros da América do Sul e/ou América Central.

“…Lines 4 and 9, and the parent 'SEKATI' generated the best results in all the variables assessed [37]. Accordingly, the use of genetic parameter estimates is relevant to show the variability of genetic materials [38,39]. In Ethiopia, black spot disease of papaya was reported 19 years back [5] and now a day the pathogen is wide spread due to its nature.…”

Papaya (Carica papaya L.) is an important fruit crop which is cultivated widely for consumption as a fresh fruit and for use in drinks, jams, candies and as dried and crystallized fruit. It has high nutritive and medicinal value. Papaya is also used as a source of cash-income. Production of papaya in Ethiopia is increasing through time; yet the average production and export is very low due to various abiotic and biotic factors. Among which, diseases cause much of the damage. Papaya is attacked by several diseases like, anthracnose, powdery mildew, black spot and papaya ring spot. Among the emerging diseases of papaya in Ethiopia, black spot disease caused by Asperisporium caricae is the most lethal by causing disease on photosynthetic and economic (fruit) plant parts. The fruits are affected on the surface, reducing the fresh-market value. In Ethiopia, Asperisporium caricae has been observed in most papaya producing areas. However, the severity of the pathogen has not been well profiled. The pathogen was not also characterized, which is the base to device management options. Currently, the use of fungicides and resistant cultivars are the preferred management options. This disease is found to be serious in the recent past few years by causing substantial economic loss. Therefore, the aim of this paper is to review the newly emerging black spot disease of papaya, its distribution and management options.

“…Brazilian papaya production is based only on a few cultivars. Papaya narrow genetic diversity, high incidence of pests, and climatic conditions compromise productivity and limit cropped area expansion (Dias, Oliveira, & Dantas, 2011;Moretti, Mattos, Calbo, & Sargent, 2010;Vivas et al, 2017). Commercially cultivated genotypes are the groups Solo and Formosa, which are distinguished by their fruit physical, physicochemical, and sensory characteristics.…”

“…The development of papaya cultivars with superior agronomic traits, disease resistance, and quality fruits that meet consumer demands is a major challenge for crop breeders, as these traits are rarely found in a single genotype (Vivas et al, 2017).…”

This study aimed to evaluate papaya elite lines and hybrids as to fruit physicochemical and sensory characteristics, thus identifying the most promising ones for the market. Fruits from improved genotypes of the Solo group (CMF H10.60, CMF L78, and UC 14) and Formosa group (CMF L10, UC 10, and UC 12) were evaluated, and the commercial cultivars Golden and Tainung nº 1 were used as controls. The following physical and physicochemical evaluations were performed: fruit length and diameter, fruit inner cavity diameter, fruit weight, fruit and pulp firmness, soluble solids, pH, titratable acidity, Ratio (soluble solids and titratable acidit relation), and firmness of peeled and unpeeled ripe fruits. Sensory tests were performed with 50 papaya consumers. In general, the improved genotypes of the Solo and Formosa groups showed similar physical and physicochemical characteristics to the Golden and Tainung n° 1 controls. The CMF L78 line of the Solo group and the UC10 hybrid of the Formosa group showed similar fruit firmness and ratio characteristics compared to both commercial cultivars. The three new genotypes in the Solo group showed superior sensory characteristics to the commercial cultivar Golden. The internal preference mapping of this group revealed a higher preference for the genotypes UC 14 and CMF L78, for having fruits with more intense color, stronger flavor, and firmer texture than the others. In the Formosa group, the UC 10 genotype outperformed the cultivar Tainung nº 1, with a global acceptance percentage of 96.15%, due to a more intense aroma, color, and flavor. The CMF L78 line of the Solo group and the UC 10 hybrid of the Formosa group have excellent physicochemical and sensory characteristics and are therefore promising alternatives to replace both commercial cultivars (Golden and Tainung nº 1).
