Spanish melons (Cucumis melo L.) of the Madrid provenance: a unique germplasm reservoir

Abstract

Melon (Cucumis melo L.

Sensorial characteristics of Spanish traditional melon genotypes: has the flavor of melon changed in the last century?

“…A loss of attributes from the traditional varieties to their commercial homologues is considerably evident (banana-mango-peach aromas, acidity, Wbrosity and orange fresh). The Piel de Sapo market class showed more sensorial homogeneity, as found in other studies [8,25,33]. Most sensorial attributes of the commercial varieties 'Piñonet Pinet' and 'Piel de Sapo Ricamiel' have weakened in the breeding process.…”

“…However, until now, no author has used a characterization protocol to obtain a sensory proWle of a set of traditional melon varieties. Some studies have demonstrated the extraordinary agro-morphological and molecular variability of these varieties, using a multidisciplinary approach [25,33]. The goal of present study is to analyze melon diversity through sensory analysis, applying the previously published protocol [8].…”

Genetic diversity and population structure of Indian melon (Cucumis melo L.) landraces with special reference to disease and insect resistance loci

“…The average alleles per locus in Spanish melons ranged from 1.05 to 2.82 (Escribano et al. ) and 2.47 in Greek and Cypriot melons (Emmanouil et al. ), compared to 4.44 for Indian melon accessions in the current study.…”

“…Fergany et al (2011) also reported a PIC value of 0.544 in a set of Indian melon accessions, which is in the range Fig 1: Two different methods for determining optimal value of K: (a) the ad hoc procedure described by Pritchard et al (2000) where the K value is increasing (b) the second-order statistic (DK) developed by Evanno et al (2005), the sharp peak of DK at K = 4 suggesting four sub populations of results obtained in the current experiment. The average alleles per locus in Spanish melons ranged from 1.05 to 2.82 (Escribano et al 2012) and 2.47 in Greek and Cypriot melons (Emmanouil et al 2009), compared to 4.44 for Indian melon accessions in the current study. Although it would not be appropriate to compare results across these experiments as the number of accessions and markers employed would influence the allele number, the current findings provide a suggestive evidence of a high variability among Indian melon germplasm.…”

“…Microsatellite markers or simple sequence repeat (SSR) markers are frequently used to evaluate the genetic diversity of germplasm collections because of their versatility, higher reproducibility and manifestation of a high degree of polymorphism (Gupta andVarshney 2000, Vignal et al 2002). SSR markers were used to study genetic diversity of melons from Greece and Cyprus (Emmanouil et al 2009), China (Kong et al 2011, Hu et al 2015, Spain (Escribano et al 2012) and Turkey (Kacar et al 2012).…”
