A new gene controlling resistance to Fusarium oxysporum f. sp. melonis races 0 and 2 in melon National Institute of Agronomic Research
Oumouloud, A.; González Torres, R.; Arnedo Andrés, M.S.; Alvarez, J.M..
‘Tortuga’ is a cantalupensis accession of Spanish origin which has proven to be resistant to Fusarium oxysporum f.sp. melonis races 0 and 2. In this work we report the results of an allellism test to assess the inheritance of this resistance. Resistance in ‘Tortuga’ seems to be controlled by two genes, one of them is the already described Fom-1, and the other is either a dominant one linked to Fom-1, or an independent recessive factor. Further work will be needed to clarify the nature of this resistance.

Characterization of the resistance to Fusarium oxysporum f. sp. melonis race 1.2 in Cucumis melo ‘BG-5384’ National Institute of Agronomic Research
Chikh-Rouhou, H.; González Torres, R.; Alvarez, J.M..
‘BG-5384’ is a melon cantalupensis accession which has been found to be resistant to Fusarium oxysporum f.sp. melonis. In this work it is shown that ‘BG- 5384’ has a high level of resistance to F. oxysporum f.sp. melonis races 0, 1, and 2. The resistance to race 1.2 appears to be polygenic controlled and partially dominant when the inoculation was done with the pathotype W of the race 1.2, and recessive when the pathotype was Y, showing that this resistance shows some race specific effects.

Diversity of Spanish landraces of Cucumis sativus and Cucurbita ssp National Institute of Agronomic Research
Esteras, C.; Diez, M.J.; Pico, B.; Sifres, A.; Valcarcel, J.V.; Nuez, F..
The Genebank of the COMAV at the UPV holds an important collection of cucurbits. It contains more than 1000 accessions belonging to the Cucurbita genus and about 180 accessions of Cucumis sativus. In this work a previously established core collection of 52 C. pepo landraces has been characterized with SSRs markers. Also the geographical variation and the utility of seed traits for classifying C. moschata accessions have been tested using a collection of 250 landraces. The variability of a collection of 63 accessions of C. sativus has been inspected using qualitative and quantitative traits. The SSR results support the idea that only a part of the great variability present in the area of origin of the species arrived into Europe. In fact some Spanish types...

Effective long-term storage methods for soft X-ray irradiated pollen, and the use of storage pollen National Institute of Agronomic Research
Akutsu, M.; Kami, D.; Sugiyama, K..
An effective long-term storage method for active soft X-ray irradiated pollen for the production of seedless watermelon (Citrullus lanatus) in diploid plants by using gas treatments is described. Soft X-ray irradiated pollen stored under N2 or CO2 gas, or under a vacuum for 1 year had high pollen germination abilities. Also, pollen stored at -25ºC under N2 gas for 1 year and mixed with an equal amount of ‘Marriage powder’ had similar results in the fruit produced. This result indicated that ‘Marriage powder’ was useful as a pollen extender medium for watermelon. Soft X-ray irradiated pollen was stored at -25ºC for about 1 week, after which the pollen was set in an incubator at 20, 25, 30, 35, or 40ºC under 50, 60, or 80 % relative humidity for 1 to 6...

Genetic diversity of Spanish melons (Cucumis melo) of the Madrid provenance National Institute of Agronomic Research
Escribano, S.; Lázaro, A.; Staub, J.E..
The genetic diversity of five winter melon landraces having a historic presence in the town of Villaconejos, Spain (near Madrid) and four reference accessions including one accession from snakemelon, was assessed using the allelic variation at 19 SSR loci. Seventy-two polymorphic bands were scored which provided for adequate discrimination among the accessions examined. Cluster analysis (UPGMA) employing SSR-based genetic similarity (GS, Jaccard similarity coefficient) data resulted in a dendrogram with two major clades. Although winter melon accessions were represented in both clades, genetic differences among two Madrid accessions and the other seven landraces were remarkable. In fact, this genetic difference (GS = 0.24; lack of genetic affinity) was...

Genetic erosion in melon (Cucumis melo): a case study from Tunisia National Institute of Agronomic Research
Elbekkay, M.; Hamza, H.; Haddad, M.; Ferchichi, A.; Kik, C..
This study reports on the analysis of 21 local melon cultivars (Cucumis melo L.) collected in the South of Tunisia which were compared to three modern melon cultivars widely-grown in this area. The analysis was based on the morphological characterization of fruits. Modern cultivars were significantly different from local germplasm as they were more firm and had higher sugar content. Furthermore it was found that local germplasm was more variable, as a group, compared to the modern cultivars which replace them steadily. This study clearly shows the need to safeguard and manage this precious local germplasm both ex situ and in situ, as this material may contain valuable genes for future breeding activities and also future cultivation practices. It can also...

Molecular characterization of different Italian inodorus melon populations based on ISSR molecular markers and preliminary SSR analysis National Institute of Agronomic Research
Sestili, S.; Daniele, A.; Rosa, A.; Ferrari, V.; Belisario, A.; Ficcadenti, N..
Cucurbitaceae, or cucurbit family, are important crops widely distributed in the warmest areas of the world supplying humans with edible products and useful fibres. Melon (Cucumis melo L.) is considered the most diversified species in the genus Cucumis. The inodorus melon varieties, commonly known as “winter melons” for their capability to be preserved during the winter time, are traditionally cultivated in the Mediterranean area and they have a relevant importance in the economy of the Italian southern regions. The genetic diversity and relationships among 13 Italian inodorus accessions of different geographic origin were revealed by using 90 ISSR primers and 18 SSR primer pairs. The DH line Nad-1 and the Charentais-T genotype, both belonging to the...

Morphological characterization of Korean and Turkish watermelon germplasm National Institute of Agronomic Research
Huh, Y.C.; Solmaz, I.; Sari, N..
A total of 67 watermelon accessions of Korean (37 accessions) and Turkish (27 accessions) germplasm and 3 accessions of other species were characterized for morphological characteristics. The accessions were characterized according to UPOV descriptor list for 56 characters (6 seedling, 4 plant, 11 leaf, 5 flower, 23 fruit and 7 seed). Eight quantitative characters (hypocotyl length, cotyledon width, cotyledon length, fruit weight, fruit length, fruit width, thickness of outer layer of pericarp and soluble solid content) were also measured. According to the results of morphological characterization performed, the accessions displayed a large diversity; however, plant growth habit and leaf blade flecking were constant characters for all the accessions. The...

Phenotyping root response to complex diseases: the Monosporascus root rot/ vine decline of melons National Institute of Agronomic Research
Roig, C.; Picó, B.; Fita, A.; Nuez, F..
Monosporascus root rot/vine decline is one of the major diseases of melon crop in warm habitats, caused by the pathogenic fungus Monosporascus cannonballus. Resistance to this disease has been reported in several sources. However, the use of resistance in breeding programs is prevented by difficulties in phenotyping the root response to the disease. The present study covers the phenotyping of an F2 population of melon, derived from a cross between C. melo subsp. melo ‘Piel de sapo’ (susceptible to vine decline) and C. melo subsp. agrestis ‘Pat81’ (partially resistant to vine decline), for root resistance to the fungus. Both, conventional methods, based on the visual scoring of the severity of root lesions, and new technologies, color image analyses and...

Reflections on linguistics as an aid to taxonomical identification of ancient Mediterranean cucurbits: the Piqqus of the Faqqous National Institute of Agronomic Research
Paris, H.S.; Janick, J..
There are a number of Mediterranean epithets for cucurbits that have intriguing connections in various ancient and modern languages. The most ancient and basic utterance is of Sumerian origin and includes a velar consonant (q, k) with a sibilant (s, sh, z). It is expressed in the Akkadian and Hebrew qishu and the Greek sikyos. The velar consonant without the sibilant is found in the Arabic qatta and doubled in the Greek kolokynthus and Latin cucumis and cucurbita. These and other possible linguistic implications and connections are considered with regard to cucurbit taxa of the ancient Mediterranean: Cucumis melo, Lagenaria siceraria, Citrullus lanatus, Citrullus colocynthis, and Ecballium elaterium.
