“…Accessions A-04, A-13, A-28 (cantalupensis), A-16 (conomon), A-43, and A-44 (inodorus) showed firmness above 30 N, and the lowest values were observed in accessions A-15 (momordica) and A-27 (not defined), which had an average of 16.4 N. Accessions showed very low values for soluble solids, for which the estimates ranged from 3.3 to 8.0 °Brix; this was unlike the observation for hybrids, which had values above 8.0 °Brix. Similar results were observed by Monforte et al (2005) and Szamosi et al (2010). However, they found lower values than Hosoki et al (1990) and López-Sesé et al (2003).…”

ABSTRACT. The genetic divergence of 38 melon accessions from traditional agriculture of the Brazilian Northeast and three commercial hybrids were evaluated using fruit descriptors and microsatellite markers. The melon germplasm belongs to the botanic varieties cantalupensis (19), momordica (7), conomon (4), and inodorus (3), and to eight genotypes that were identified only at the species level. The fruit descriptors evaluated were: number of fruits per plant (NPF), fruit mass (FM; kg), fruit longitudinal diameter (LD; cm), fruit transversal diameter (TD; cm), shape index based on the LD/TD ratio, flesh pulp thickness, cavity thickness (CT; cm), firmness fruit pulp (N), and soluble solids (SS; °Brix). The results showed high variability for all Genetic diversity of Cucumis melo from Brazilian Northeast descriptors, especially for NPF, LD, and FM. The grouping analysis based on fruit descriptors produced eight groups without taxonomic criteria. The LD (22.52%), NPF (19.70%), CT (16.13%), and SS (9.57%) characteristics were the descriptors that contributed the most to genotype dissimilarity. The 17 simple sequence repeat polymorphic markers amplified 41 alleles with an average of 2.41 alleles and three genotypes per locus. Some markers presented a high frequency for the main allele. The genetic diversity ranged from 0.07 to 0.60, the observed heterozygosity had very low values, and the mean polymorphism information content was 0.32. Molecular genetic similarity analyses clustered the accessions in 13 groups, also not following taxonomic ranks. There was no association between morphoagronomic and molecular groupings. In conclusion, there was great variability among the accessions and among and within botanic groups.

-The aim of this work was to perform botanical identification and to estimate genetic diversity in two sequential inbred generations (progenies S 1 and S 2 ) of melon accessions from traditional agriculture in the state of Maranhão, in order to generate useful information for commercial melon breeding. Two field experiments were carried out in a completely randomized block, using four replicates of 15 accessions from a first selfing cycle in 2013, and three replicates of 25 subaccessions (generation S 2 ) in 2014. Flower and fruit descriptors were measured to obtain quantitative and qualitative data, in addition to a systematized photographic documentation of fruit for visually comparing the progenies S 1 and S 2 . Distance matrices for quantitative and qualitative data were obtained and used to perform a joint analysis and UPGMA method. Large genetic diversity was found in the accessions analysed, since the presence of melon progenies was observed in the Cucumis melo ssp. agrestis, with its botanical varieties momordica and conomom, and of the Cucumis melo ssp. melo, with the botanical varieties cantalupensis and chandalak. Divergence analysis showed the formation of three groups in generation S 1 and four groups in S 2 . However, the groups were not separated either by subspecies or by botanical variety. Thus, in addition to the large genetic diversity among and within melon accessions from family farming in the state of Maranhão, the progenies presented a large introgression of traits of the different subspecies and their botanical varieties due to the reproductive system and seed management of these species.Keywords: Botanical variety.

Foram conduzidos dois experimentos de campo em blocos casualizados completos, com quatro repetições e 15 acessos em 2013 e, três repetições e 25 subacessos em 2014. Para avaliação dos acessos foram aplicados descritores quantitativos e qualitativos de flor e fruto, além de uma documentação fotográfica sistematizada dos frutos com análise visual, comparando os frutos das gerações S 1 e S 2 . Foram obtidas as matrizes de distância nos dois tipos de descritores e se fez a análise conjunta e em seguida realizou-se o agrupamento pelo método UPGMA. Verificou-se que nos acessos analisados, existe uma grande diversidade genética, pois foram encontradas progênies de melão da subespécie agrestis e suas variedades botânicas momordica e conomom e da subespécie melo com as variedades botânicas cantalupensis e chandalak. A análise de divergência na geração S 1 mostrou a formação de três grupos e na geração S 2 foram formados quatro agrupamentos, entretanto os grup...

Over the past century, Israel was a focal point for the improvement of local cucurbit landraces and introduction of cucurbit germplasm. Some improved open-pollinated cucurbit cultivars developed in Israel became established as market types of considerable economic importance far beyond its borders. The origin and history of these cultivars is not widely known and therefore the purpose of the present work was to collect and compare the records relevant to the development of these cultivars, and to describe them more fully. The four economically most important cultivars originated through mass-selection by amateur breeders and were named after their respective farming communities. The 'Bet Alfa' cucumber (Cucumis sativus) was selected from a local landrace and introduced in 1936. The 'Malali' watermelon (Citrullus lanatus) originated as a rogue in a local landrace and was commercialized around 1940. The 'Ananas Yoqne'am' melon (Cucumis melo) was selected from a local landrace and commercialized around 1950. The 'Ha'Ogen' melon was selected from a cultivar introduced from Hungary and commercialized in the 1950s. The outstanding fruit quality of these four cultivars resulted in their widespread planting in Israel and neighboring countries. Moreover, the quality of the cucumber and melon cultivars inspired successive improvements, notably introgression of disease resistance and development of hybrids, by Israeli breedergeneticists. The ever-increasing demand for their highquality fruits established as international market types the Bet Alfa cucumber, the Ananas Yoqne'am melon, and the Ha'Ogen melon and its derivative, the Galia melon, and each is intensively bred today by local and multinational seed companies.
