Quality Features

While supermarkets devote whole aisles to hybrids, traditional varieties are hard to find, and becoming scarcer day by day. Unfortunately, countless old melon varieties have already been lost. Luckily we succeded in collecting most of these varieties, and thus conserving them in Gene Banks. Landraces, local types, and old breed races show many characteristics that could be useful in organic farming. It is important to get acquainted with these varieties and cultivars, because they have greatly adapted to the climatic and pedological conditions of the Carpathian basin. Therefore their conservation is essential for the protection of Hungarian genetic variability. With the help of utilising our landraces in organic farming; careful selection; and the usage of marketing strategy in order to enhance quality features, such as unique flavour; we could reclaim the one-time excellent reputation of Hungarian melon.

E-mail: [email protected]  1 RESUMO  Neste trabalho, estudou-se o efeito da água com diferentes níveis salinos em termos de condutividade elétrica (CE = 1,1; 2,5 e 4,5 dS.m-1) e duas frequências de irrigação (1 e 2 dias) na produção da cultivar de melão do tipo HoneyDew (Orange Flesh) e a do tipo cantaloupe (Trusty), em solos de textura franco-arenosa na Fazenda São João Ltda, município de Mossoró-RN. Adotou-se o delineamento experimental em blocos ao acaso no esquema fatorial 3x2x2 com quatro repetições. Dos resultados obtidos, concluiu-se que mesmo sob estresse, a produção de melão irrigado com águas nos níveis salinos de 1,1 dS.m-1 até 2,5 dS.m-1, consegue-se produções economicamente viáveis em relação ao irrigado com as águas de 4,5 dS.m-1. A cultivar Orange Flesh mostrou ser mais sensível aos efeitos dos sais que a Trusty em todos os parâmetros avaliados, demonstrando ser esta última medianamente tolerante aos efeitos deletéricos, reduzindo sua produtividade apenas no nível salino 4,5 dS.m-1, em conformidade com a literatura.  UNITERMOS: Cucumis melo L., salinidade, produção, freqüência  BARROS, A. D.; SOUSA, A. P.; MEDEIROS, J. F. MELON PRODUCTIVE BEHAVIOR IN RELATION TO WATER SALINITY AND IRRIGATION FREQUENCY  2 ABSTRACT  This work has studied the effect of different water salinity levels in terms of electrical conductivity (CE = 1.1; 2.5 and 4.5 dS.m-1) and two irrigation frequencies (1 and 2 days) on HoneyDew (Orange Flesh) and cantaloupe (Trusty) melon production, in loam sand soils in São João Ltda farm, municipal district of Mossoró-RN. The experiment was a 3x2x2 factorial randomized block design with four replications. The results allowed to conclude that even under stress, irrigated melon production at 1.1 dS.m-1 up to 2.5 dS.m-1 saline level water , make production economically feasible in relation to the one at 4.5 dS.m-1 saline level water. Orange Flesh seemed to be more sensitive to the salt effects than the Trusty cultivar in all appraised parameters. Trusty cultivar has shown to be reasonably tolerant to the deleterious effects, decreasing its  productivity only at  4.5 dS.m-1 saline level , which is according to the literature.  KEY-WORDS: Cucumis melo L., salinity, production, frequency

O experimento foi conduzido na área experimental do Departamento de Engenharia da Universidade Federal de Lavras, Lavras/MG. A cultivar utilizada foi a Vereda, variedade Inodorus, e a irrigação da cultura foi por gotejamento sendo aplicada quatro lâminas, com turno de rega de dois dias. A evapotranspiração da cultura (ETc) foi calculada com base na evaporação do tanque classe A reduzido (ECA) a as lâminas líquidas (LL) aplicadas foram equivalentes a 0,5.LL, 0,75.LL, 1,0.LL e 1,25.LL. Cada parcela foi composta de 3 linhas com oito plantas por linha. Foi considerado planta útil as seis plantas da linha central de cada tratamento. As características avaliadas foram a altura de planta e diâmetro do caule, o peso médio, o diâmetro longitudinal e transversal dos frutos colhidos das plantas úteis de cada tratamento. O peso médio e os diâmetros longitudinal e transversal dos frutos não foram influenciados significativamente pelas lâminas aplicadas, entretanto apresentou tamanho abaixo do exigido pelo mercado. A altura e o diâmetro do caule tendem a ser maior na lâmina de irrigação equivalente a 0,75LL. UNITERMOS: lâmina de irrigação, Cucumis melo L., peso de fruto, LIMA, E.

GROWTH AND PRODUCTION OF MELON CULTIVATED IN GREENHOUSE UNDER DRIP IRRIGATION   2 ABSTRACT The objective of this study was to evaluate the effect of different irrigation depths on melon growing in greenhouse. The experiment was conducted in an experimental area of the Engineering Departament of the Universidade Federal de Lavras, Lavras/MG. Melon (Cucumis melo L., var. Inodorus, cv. Vereda) was drip irrigated, in a two-day interval, with four different depths. Crop evapotranspiration (ETc) was calculated with a reduced class A pan evaporimeter (ECA). Irrigation depths were input using four different fractions of the net depth (LL): 0.5.LL, 0.75 LL, 1.0.LL and 1.25.LL. Each irrigation treatment was applied to three plants rows, each one containing 8 plants. Only 6 plants located at the central row of each treatment were used for measurement. Evaluated parameters were: plant height, stem diameter measures, average weight and fruit longidutinal and transversal diameters. Average weight and fruit longidutinal and transversal diameters were not significantly affected by irrigation depth; however, they  presented smaller size  than the one demanded by the market. Plant height average and stem diameter average measurements showed tendency to be higher on the irrigation depth equivalent to 0.75.LL. KEYWORDS: irrigation depth, Cucumis melo L., fruit weigth.

Cucumis Melo L

Melon (Cucumis melo L.) is an economically important horticultural crop with abundant morphological and genetic variability. Complex genetic variations exist even among melon varieties and remain unclear to date. Therefore, unraveling the genetic variability among the three different melon varieties, muskmelon (C. melo subsp. melo), makuwa (C. melo L. var. makuwa), and cantaloupes (C. melo subsp. melo var. cantalupensis), could provide a basis for evolutionary research. In this study, we attempted a systematic approach with genotyping-by-sequencing (GBS)-derived single nucleotide polymorphisms (SNPs) to reveal the genetic structure and diversity, haplotype differences, and marker-based varieties differentiation. A total of 6406 GBS-derived SNPs were selected for the diversity analysis, in which the muskmelon varieties showed higher heterozygote SNPs. Linkage disequilibrium (LD) decay varied significantly among the three melon varieties, in which more rapid LD decay was observed in muskmelon (r2 = 0.25) varieties. The Bayesian phylogenetic tree provided the intraspecific relationships among the three melon varieties that formed, as expected, individual clusters exhibiting the greatest genetic distance based on the posterior probability. The haplotype analysis also supported the phylogeny result by generating three major networks for 48 haplotypes. Further investigation for varieties discrimination allowed us to detect a total of 52 SNP markers that discriminated muskmelon from makuwa varieties, of which two SNPs were converted into cleaved amplified polymorphic sequence markers for practical use. In addition to these markers, the genome-wide association study identified two SNPs located in the genes on chromosome 6, which were significantly associated with the phenotypic traits of melon seed. This study demonstrated that a systematic approach using GBS-derived SNPs could serve to efficiently classify and manage the melon varieties in the genebank.

Cucumis Melo L

A set of 40 genotypes of muskmelon (Cucumis melo L.) were evaluated in a randomized block design with two replications under different water regimes during summer 2012 at the agriculture research station Bee-chwal, Bikaner, Rajasthan, India to study genetic variability among the traits to determine selection criteria for breed-ing programmes for fruit yield and related characters. The results reported that drought stress caused reduction in fruit yield and most of the characters studied. Significant variations for all the characters were found under different water regimes (non-stress, 50% and 25%). High genotypic (GCV) and phenotypic (PCV) coefficient of variations were observed for fruit yield per plant, fruit weight per plant, vine length and proline content in non-stress, 50% and 25% water stress conditions respectively. High estimates of heritability along with high genetic advance as percent-age of mean over the characters was recorded for fruit weight (128.79, 164.05, and 161.15), proline content (42.50, 72.86 and 69.26) and fruit yield per plant (149.61, 186.91 and 184.12) in both the non-stress and stress conditions. This shows that these traits were under the control of additive genetic effects. Therefore, it was concluded that se-lection for these traits should lead rapid genetic improvement of the material.
