“…The summer harvest provided a higher NCF and NDF (Table 3), as observed by Silva et al (2007). Martelleto et al (2011) evaluated the floral behavior of papaya in four cropping systems, and reported that the environmental and phenological conditions favorable to the production of normal fruits and carpeloids were the same, which confirms that there is a positive correlation between these variables.…”

-The objective of this work was to evaluate the productivity and quality of papaya fruits (Carica papaya) of the Solo (12 genotypes) and Formosa (9 genotypes) heterotic groups over two harvest seasons. The experiment was conducted under field conditions in the municipality of Pinheiros, in the state of Espírito Santo, Brazil, in a randomized complete block design. Ten morpho-agronomic and physicochemical variables of the fruits were measured in winter (210-300 days after planting) and summer (450-540 days after planting). The data were subjected to the combined analysis of variance, to the breakdown of the genotype x environment interactions, and to the grouping of means by the Scott-Knott test. Although harvest season affected the evaluated characteristics, it did not alter the classification of the genotype. In the Solo group, the H 36-45 and UC 15 hybrids stand out due to their greater productivity, fruit weight, and soluble solids contents. In the Formosa group, the Rubi Incaper 511 cultivar shows greater productivity, higher number of commercial fruits, and lower number of deformed fruits over both evaluated harvest seasons.Index terms: Carica papaya, agronomic performance, environmental effect, genotype evaluation. Produtividade e qualidade de frutos de mamão Formosa e Solo em duas épocas de colheitaResumo -O objetivo deste trabalho foi avaliar a produtividade e a qualidade de frutos de mamoeiro (Carica papaya) dos grupos heteróticos Solo (12 genótipos) e Formosa (9 genótipos), em duas épocas de colheita. O experimento foi conduzido em condições de campo em Pinheiros, ES, em delineamento de blocos ao acaso. Dez variáveis morfoagronômicas e físico-químicas dos frutos foram avaliadas no inverno (210 a 300 dias após o plantio) e no verão (450 a 540 dias após o plantio). Os dados foram submetidos à análise de variância conjunta, à decomposição da interação genótipo x ambiente e ao agrupamento das médias pelo teste de Scott-Knott. Embora a colheita em diferentes épocas tenha influenciado as características avaliadas, não alterou a classificação dos genótipos. No grupo Solo, destacam-se os híbridos H 36-45 e UC 15, por suas maiores produção e massa do fruto e por seu alto teor de sólidos solúveis. No grupo Formosa, a cultivar Rubi Incaper 511 apresenta maior produção, maior número de frutos comerciais e menor número de frutos deformados nas duas épocas de colheita avaliadas.Termos para indexação: Carica papaya, desempenho agronômico, efeito ambiental, avaliação de genótipos.

“…Papaya blooms and produces fruits continuously for up to two years after reaching reproductive maturity (Martelleto et al, 2013). Despite this, floral behavior, which is highly sensitive to environmental factors, may negatively affect fruit production, leading to sexual reversion, carpelloidy, and pentandry (Damasceno Júnior et al, 2008).…”

“…This phenomenon, known as summer sterility (Storey 1958), is one of the main causes of decreased production in some periods of the year, since it concentrates production in certain seasons. Martelleto et al (2011) carried out an experiment to compare fruiting in a variety of papaya in different seasons of the year, under greenhouse and field conditions, and estimated the number of carpelloid, pentandric, and normal (commercial) fruits. The data obtained by these authors corroborate the reports of Silva et al (2007a) and Damasceno Júnior et al (2008) on increased sterility and increased number of deformed fruits in different seasons of the year.…”

The present work aimed to estimate the adaptability and stability of new papaya hybrids. The experiments were carried out at the company Caliman Agrícola S/A, in the municipalities of Linhares-ES and Pureza-RN, with seven hybrids from inbred parents of the groups 'Solo' and 'Formosa' and three controls ('Golden', 'Calimosa', and 'Tainung 01'). The experiment consisted of a randomized block design with four replications and ten plants per plot. The variables mean fruit weight (MFW), number of commercial fruits (NCF), and production (PROD) were measured at 270, 360, 450, and 540 days after planting. Afterward, the adaptability and stability of the hybrids were estimated using the Lin and Binns, Eberhart and Russell, and Mixed Models. MFW was less affected by the evaluation periods and showed high behavior predictability. The hybrids UC10, UC12, UC14, UC15, and UC16 were the most adapted and predictable and can be recommended for the regions where the experiment took place.

“…Also in agreement with Damasceno Junior et al (2008) and Silva et al (2007), low temperatures may contribute to increased carpelloidy. Martelleto et al (2011) carried out a study with cultivar Baixinho de Santa Amália, with manually bifurcated trunks. The authors observed little occurrence of carpelloid fruits and a large number of summer sterile flowers.…”

Floral abnormalities in papaya cause fruit deformation and yield reduction in some periods of the year. This study aimed to evaluate 23 inbreed lines and 22 hybrids in crosses between the lines Solo and Formosa in relation to floral abnormalities, and to develop a methodology to estimate summer sterility by counting of nodes without fruits. The traits evaluated were: number of carpelloid and pentandric fruits (in March and July 2007); number of nodes without fruit and neck length (in December 2006 and April 2007); and sum of abnormalities. Hybrids presented means higher than those of the lines for all abnormalities. The capelloidy was seasonal only for lines, and the pentandry showed the lowest coefficients of determination for lines and hybrids. The number of nodes without fruit was adequate to infersummer sterility. This anomaly was the most important in the lines and hybrids.
