“…The 44 loci amplified a total of 202 alleles with a mean of 4.59 alleles per locus (Table S4); an allele number superior to that described by Aragão (2010), who analyzed 41 melon accessions using 17 SSR primers, also developed by Ritschel et al (2004), who amplified 41 alleles. This allele number is superior to that described by Kaçar et al (2012), who studied the genetic diversity of 81 melon genotypes of Turkey in comparison to 15 reference genotypes obtained in France. These authors amplified 123 alleles from 20 SSR primers with a mean of 6.15 alleles per locus; this medium is superior to the one found in this study.…”

ABSTRACT. Taking into account the scenario of melon production (Cucumis melo L.) in Brazil, it is notable the importance of the culture in the fruit market. The preference of the national market is concentrated in the fruits of the yellow type. Therefore, it is possible that the genetic base of the commercial cultivars is relatively narrow due to the loss of important genes in the breeding process, and it is possible to introgress external genes for increasing recombination possibilities that generate sources of resistance to the main diseases and superior genotypes. This study evaluated the genetic variability of 87 melon accessions composed of 72 commercial cultivars belonging to the Inodorus and Cantaloupensis groups and 15 plant introductions (PIs). Forty-four polymorphic SSR primers were used to amplify a total of 202 alleles. The expected heterozygosity presented an average of 0.519 and the PIC index of 0.458, being moderately informative. The dendrogram generated for the 72 cultivars grouped the genotypes into 2 main groups, and there was no association with the classification of groups of the genotypes in the grouping. The number of SSR markers was sufficient to predict wide genetic variability among the cultivars studied, with the similarity between 0.35 and 0.98. The dendrogram presented for the 72 cultivars and the 15 PI genotypes was not associated with the classification of the genotypes in the grouping, and the 15 PIs were well dispersed with similarity indexes that resemble the two groups studied. A set of 25 primers was identified that were useful in distinguishing the 72 cultivars. These primers can be used in later research with the cultivars, as well as in crop protection situations, being an important tool in the useful and rapid distinction of genotypes, and in commercial disputes regarding the certification of the main melon cultivars used in the country.

“…Similar results have been determined by Sensoy et al (2007) that distinction amon inodorus group and cantalupensis group (sweet) genotypes was also not very significantly different in their evaluations. Also, Kacar et al (2012) have been documented that cantalupensis group and inodorus group were clustered together with varying (70-100%) similarity rates.…”

Twenty-four accessions covering different groups of Cucumis melo L. from Eastern and South-eastern Anatolian regions of Turkey were characterized by using 43 morphological traits and 207 markers obtained from 31 ISSR and 16 SSR primers. The genetic relatedness was studied by examining the Euclidian/UPGMA dendrogram obtained from the combined phenotypicmolecular data. In the combined morphological-molecular dendrogram, there were two main clusters. Sweet and non-sweet melon groups were separated and the flexuosus group accessions were discriminated from the sweet ones, but the momordica group accession was clustered with the sweet ones. Unclear South-eastern Anatolian accessions were sub-clustered separately among the sweet ones. Principle component analysis (PCA) of morphological characters was used in detail to discriminate melon accessions. The cumulative proportion of variation reached 44% by first three PCA axes. The first component was mainly based on sex expression, ovary index, ovary shape, flesh thickness, seed cavity length, seed cavity width, soluble solids content, fruit shape, aroma, netting, and taste. The PCA plot based on all measured traits allowed distinction between flexuosus group, subsp. agrestis and reticulatus group. A high variation among groups was observed for the fruits characters. Netting, aroma and abscission of peduncle represent reticulatus group; a small fruit size, strong typical aroma and secondary colour distribution characterize dudaim group. Monoecy, very long fruit shape and mature fruit rind colour discriminate flexuous group; Ovary index, fruit size and flesh width distinguish subsp. agrestis group. These findings indicated wide range of variations for investigated characteristics in Turkish gene pool that provides a good source of diversity to use in melon improvement program for better yield and other traits of interest.

“…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).…”

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

This study was aimed to examine the genetic diversity and population structure of Indian melon landraces with special reference to disease and insect resistance loci. Thirty-six simple sequence repeat (SSR) markers along with seven markers at disease and insect resistance loci were used for this purpose on a panel of 91 accessions available at Indian Institute of Horticultural Research, Bengaluru, India. Model-based structure analysis revealed the presence of four groups that were consistent with the results of principal coordinate analysis (PCoA). The delineation of populations was mostly based on geography with improved varieties as a separate group. Ten accessions have been identified to possess beneficial alleles at all the selected disease resistance loci and shall be useful for incorporating multiple disease resistance after phenotypic validation. The results obtained in the current study demonstrate the importance of the Indian melon group as a valuable genetic reservoir and the need to plan strategies for its conservation and utilization in breeding programmes.
