The creole melon cantaloupe is a horticultural species, whose fruits are used for human nutrition. However, no research has been reported on their genetic variability for starting breeding processes. The objective of this study was to take advantage of the variability of creole melons for genetic improvement. 20 creole melon half-sib families were selected and evaluated for production characteristics and fruit quality in order to obtain improved populations. The study was carried out in Palenque canton, Ecuador. Seeds from 20 half-sib families were used, arranged in a randomized complete block design with three replications. The differences between the families were significant for all the studied characteristics. Family 93 presented higher averages for fruit weight, fruit diameter and production (per hectare), and family 196 did so for soluble solids. The phenotypic correlations were positive and significant between the fruit weight and fruit diameter, fruit length, pulp thickness, fruit cavity, soluble solids and production. The coefficients of genetic variation, in general, were lower than the coefficients of environmental variation. The estimates of heritability broadly had a moderate magnitude (30-60%) for the 10 evaluated characteristics, and the magnitude of the expected genetic progress was low (<10%) for the fruit weight, production, and soluble solids, so the selection for high production should focus on fruit weight and soluble solids.

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

ABSTRACT The use of shading screen in vegetable crops sensitive to the radiation excess, associated with the effective water use via irrigation, allows for yield gains. This study aimed to evaluate the yield characteristics of cherry tomato cultivated with and without shading screen and different irrigation levels. A randomized block design was used, in a 4 x 2 factorial arrangement, with four irrigation levels (140 %, 160 %, 180 % and 200 % of the reference evapotranspiration - ETo) and two cherry tomato hybrids (Wanda and Dolcetto). The irrigation level corresponding to 200 % of the ETo provided the highest values for number of flowers and clusters formed, number of fruits per plant and fruit diameter. The Wanda hybrid was more fruitful, with a higher emission of clusters, while Dolcetto was more floriferous. The use of shade screen for cultivating cherry tomato provides an increase in the yield characteristics, if compared to the cultivation in open areas.

As parcelas foram as lâminas de irrigação:  60; 80; 100; e 120% da evapotranspiração da cultura (ETc), as subparcelas foram cinco doses do bioestimulante Stimulate®: 0; 0,6; 1,2; 2,4 e 4,8 L ha-1, e as subsubparcelas foram dois períodos de cultivo: quente e frio. Foram avaliadas as variáveis produtividade total e comercial, peso médio do fruto comercial, sólidos solúveis totais (SST), pH, acidez total titulável (ATT) e firmeza de polpa (FP). A dose de 4,8 L ha-1 com a lâmina de 120% da ETc, no período quente, promoveram melhores condições de desenvolvimento e, consequentemente, um maior incremento na produtividade quando comparado com o período frio do semiárido brasileiro. A qualidade dos frutos foi influenciada pelo maior teor de SST no período quente e ATT no período frio, submetida à dose de 4,8 L ha-1 do Stimulate® e às lâminas abaixo de 100% da evapotranspiração da cultura.   Palavras-chave: períodos, irrigação, Cucumis melo L., produtividade, qualidade do fruto.     LIMA, D.

The plots were the irrigation depths: 60; 80; 100; and 120% of the culture evapotranspiration (ETc), the subplots were five doses of the Stimulate® biostimulant: 0; 0.6; 1.2; 2.4 and 4.8 L ha-1, and the sub-plots were two growing periods: hot and cold. The variables total and commercial productivity, the average weight of the commercial fruit, total soluble solids (SST), pH, total titratable acidity (ATT) and pulp firmness (FP) were evaluated. The dose of 4.8 L ha-1 with a depth of 120% of ETc, in the hot period, promoted better conditions of development and, consequently, a greater increase in productivity compared to the cold period of the Brazilian semiarid region. The quality of the fruits was influenced by the higher SST content in the hot period and ATT in the cold period, submitted to a dose of 4.8 L ha-1 of Stimulate® and to the depths below 100% of the crop evapotranspiration.   Keywords: periods; irrigation, Cucumis melo L., productivity, fruit quality

Os tratamentos foram compostos mediante a combinação de três fatores: profundidade de instalação das linhas de porta-gotejadores (0 e 0,2 m da superfície do solo), três lâminas de irrigação (1, 1/3 e 2/3 da evaporação diária do mini tanque evaporimétrico) e quatro dosagens de potássio (0, 6, 9 e 12 g de K2O por planta). O delineamento estatístico adotado foi o de blocos casualizados completos com 3 repetições, arranjados em esquema fatorial 2 x 3 x 4. Os resultados mostraram que a firmeza da polpa foi menor para as dosagens de potássio de 0 e 9 g de K2O por planta, diminuindo com o incremento da lâmina de irrigação em linhas de porta-gotejadores subsuperficiais. Houve efeito linear decrescente da espessura da casca para maiores lâminas de irrigação e maiores dosagens de potássio aplicada em gotejamento subsuperficial, enquanto que, em gotejamento superficial, o efeito sobre a espessura da polpa foi linear crescente para maiores lâminas de irrigação e linear decrescente para aumentos da dose de potássio.  UNITERMOS: manejo da fertirrigação, portagotejadores, Cucumis melo L.   FOLEGATTI, M.

The statistical test was done in randomized blocks, with three repetitions, arranged in factorial design: 2 x 3 x 4. Results showed that flesh firmness was smaller for dosages of 0 and 9 g K2O plant-1. Flesh firmness also decreased when there was an increase in the irrigation level of the subsurface dripper installation. There was a linear decrease effect for skin thickness caused by greater irrigation levels and greater potassium dosages, using subsurface drippers. In surface drip fertirrigation, a linear increase effect for flesh thickness caused by greater irrigation levels was observed, while a linear decrease occurred because of potassium dosage increase.  KEYWORDS: fertigation management, dripper, Cucumis melo L.

In different crop plants, combining ability and heterosis are used as important diagnostic tools for assessing the performance of parental genotypes and their hybrids. This research aimed to evaluate heterotic and combining ability effects in the diallel crosses of melon (Cucumis melo L.) for yield- and quality-related traits. Seven melon (C. melo L.) genotypes were grown and crossed in a complete diallel fashion to produce F1 hybrids. During the 2019 crop season, 49 melon genotypes (7 parents + 42 F1 hybrids) were grown in a randomized complete block design with three replications. Observations were made for seven characters. Analysis of variance revealed significant (P ≤ 0.01) differences among the melon genotypes for harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit diameter and merely significant differences (P ≤ 0.05) for fruit weight. Combining ability analysis revealed that mean squares due to general combining ability (GCA) were significant for fruit diameter but were nonsignificant for all other traits. However, mean squares due to specific combining ability (SCA) were significant for all traits. The parental genotypes PK-165, PK-464, and PK-669 exhibited the highest and desirable GCA effects for yield and quality traits. Hence, these genotypes could be used to generate high-yielding hybrid/open-pollinated cultivars. GCA:SCA ratios further revealed that the traits of harvest age, fruit flesh thickness, fruit total soluble solids, fruit length, and fruit weight were controlled by dominant gene action, whereas fruit diameter was managed by additive and dominant genes. The majority of the traits were controlled by nonadditive gene action, verifying that the said breeding material could be efficiently used for the production of hybrid cultivars on the basis of heterotic effects.

The growth parameters that observed by the writer were stem diameter at 15, 30, and 45 Days After Planting (DAP) and main stem length at age 15 and 30 DAP. The variables of plant which was observed were plant age at flowering, the number of flowers aged 15,and 30 DAP, harvest age, fruit weight, fruit diameter, and production.The results showed that pruning had significant effect on fruit weight and diameter of melon fruit, but had no significant effect on stem diameter at age 15, 30, and 45 DAP, length of main stem at age 15 and 30 DAP, number of flowers at age 15 and 30 DAP, harvest age, and melon production. The best melon pruning is found on the main stem pruning on the 15th and left 2 lateral branches.The results showed that the arrangement of fruit amount had no significant effect on stem diameter at age 15, 30, and 45 DAP, length of main stem at age 15 and 30 DAP, number of flowers at age 15 and 30 DAP, harvest age, fruit weight, fruit diameter, and melon production. The best fruit that produces fruit weight tends to be greater in the treatment of 1 fruit per plant.There is no significant interaction between pruning and the arrangement of the number of fruits against all observed variables. It shows that the growth and yield of melon plats is not affected by pruning and arrangement of fruit amount. Keywords: Pruning, Arranging the Number of Fruits and Melon.
