“…Crop landraces represent a source of useful genes with a high capacity to endure biotic and abiotic stresses, resulting in high yield stability, disease resistance, and moderate yield level under a low input agricultural system [ 9 ]. Farmers in Palestine have conserved the diversity of snake melon, in the form of four landraces, as a primary gene pool: White Baladi (WB), Arabic Baladi Abiadh; Green Baladi (GB), Baladi Akhder; White Sahouri (WS), Sahouri Abiadh; and Green Sahouri (GS), Sahouri Akhder [ 10 ]. However, melon landraces are currently threatened by severe genetic erosion caused by improper management and the replacement of local cultivars by improved ones.…”

“…An understanding of the genetic diversity of snake melon is important to prevent the deterioration of cultivated gene pools and to guide the use of genetic resources in breeding programs [ 10 , 11 ]. Several molecular markers have been successfully used to investigate the phylogenetic relationships and the genetic diversity of melons and its close relatives.…”

BackgroundCrop landraces embody a source of beneficial genes potentially providing endurance to environmental stress and other agronomic qualities including yield. Our study included 88 snake melon accessions (Cucumis melo var. flexuosus) collected from 9 districts in the Palestinian West-Bank. These accessions represent four landraces of Palestinian snake melon: Green, and White Baladi, and Green, and White Sahouri.ResultsThis is the first report on successful application of genotyping by sequencing in snake melon. Nine thousand seven hundred fifty single-nucleotide polymorphism (SNP) and 7400 DArTseq genetic markers were employed to evaluate genetic biodiversity and population structure of Palestinian snake melon germplasm collection. Clustering based on neighbor-joining-analysis, principle coordinate and Bayesian model implemented in Structure showed that patterns of genetic diversity of snake melon landraces depends on their geographical source and unraveled the presence of two major local landraces (Sahouri, and Baladi) with accessions from each group clustering together. A significant correlation was observed between both types of markers in Mantel correlation test. A significant association between genetic and geographic matrices (P < 0.0001) was also detected. AMOVA indicated that majority of variation (90%) was due to the difference within accessions.ConclusionThe Palestinian landraces seem to have unique genes that may allow the enhancement of the global snake melon gene pool and developments of the plant production worldwide. Our subsequent objective is to detect genotypes with promising qualities and to conduct association mapping studies concentrating on Fusarium-wilt resistance, yield, and environmental stresses.Electronic supplementary materialThe online version of this article (10.1186/s12870-018-1475-2) contains supplementary material, which is available to authorized users.

“…Kandungan mineral pada buah melon antara lain adalah kalium, kalsium, Fe, magnesium, fosfor, natrium, dan seng, sedangkan kandungan vitamin pada buah melon yaitu vitamin C, A, B-6, E, dan K (USDA, 2016). Selain memiliki kandungan nutrisi yang bermanfaat, melon juga merupakan tanaman yang memiliki keragaman genetik yang tinggi (Robinson dan Decker-Walters, 1999;Nuñez-Palenius et al, 2008;Ali-Shtayeh et al, 2015) yang dapat dimanfaatkan untuk merakit varietas unggul baru melalui program pemuliaan tanaman.…”

“…Analisis ragam menunjukkan pengaruh utama genotipe yang nyata terhadap semua karakter kuantitatif yang diamati kecuali panjang buah dan kandungan vitamin C (Tabel 1). Hal ini mengindikasikan adanya keragaman sifat diantara genotipe uji yang bermanfaat dalam program pemuliaan melon, sekaligus sebagai koleksi plasma nutfah (Ali-Shtayeh et al, 2015). Malik et al (2014) Eagle memiliki rata-rata diameter buah terbesar (> 11.0 cm), sedangkan genotipe P29, P27, P311, dan P34 memiliki diameter buah relatif kecil (9.5-10.4 cm).…”

Potassium (K) is a mineral nutrient needed by crops that influences the quality of fruits and vegetables. The objective of this study was to elucidate the interaction effects of genotype by KNO3 treatment (G × KNO3) on fruit traits of melon. The experiment was conducted from August to October 2016 at Tajur II Experimental Station of IPB, Bogor, following a split plot design with three replicates. The main plot was two levels of KNO3 and the subplot was eight genotypes, consisting of seven test genotypes and one check variety (Eagle). The KNO3 treatments were applied weekly, started from 7-49 DAP with 5 g L-1 concentration, ±200 ml plant-1. G × KNO3 interaction effects were significant for sugar content and titratable acidity (TA). P34 had relatively high sugar content and TA. P25 showed a significant increase of sugar content when KNO3 is added, while Eagle, P311, and P34 showed significant decrease of sugar content. Days to male flowering, days to hermaphrodite flowering, and fruit weight had high broad sense heritability (repeatability), while days to harvest, fruit diameter, flesh thickness, rind thickness, and sugar content had moderate heritability. Fruit weight had significant positive correlation with fruit diameter, flesh thickness, and rind thickness. Application of KNO3 fertilizer in practical is therefore suggested for the postive-response genotypes to KNO3.Key words: fruit quality, KNO3, melon, sugar contentABSTRAKKalium (K) merupakan mineral yang dibutuhkan oleh tanaman yang berpengaruh terhadap kualitas buah dan sayur. Pada budidaya melon umumnya, sumber mineral K diperoleh dalam bentuk KNO3. Penelitian ini bertujuan mengidentifikasi pengaruh interaksi genotipe × perlakuan KNO3 (G × KNO3) terhadap peningkatan kualitas buah melon. Percobaan dilakukan pada bulan Agustus sampai Oktober 2016 di Kebun Percobaan IPB Tajur II, Bogor menggunakan rancangan petak terbagi (split plot design) dengan tiga ulangan. Petak utama merupakan perlakuan KNO3 dengan dua taraf, dan anak petak merupakan genotipe dengan delapan taraf, yang terdiri dari tujuh genotipe uji dan satu varietas pembanding (Eagle). Perlakuan KNO3 dilakukan setiap minggu mulai 7–49 HST dengan konsentrasi 5 g L-1 dan volume aplikasi ± 200 ml tanaman-1. Interaksi G × KNO3 berpengaruh nyata terhadap karakter kadar gula dan total asam tertitrasi (TAT). Genotipe P34 memiliki kadar gula dan TAT yang relatif tinggi. P25 merupakan genotipe yang menunjukkan respon positif berupa peningkatan kadar gula pada perlakuan KNO3, namun sebaliknya genotipe Eagle, P311, dan P34 justru menunjukkan penurunan kadar gula yang signifikan pada perlakuan KNO3. Karakter yang memiliki nilai heritabilitas (repeatabilitas) arti luas yang tergolong tinggi adalah umur berbunga jantan, umur berbunga hermaprodit, dan bobot buah, sedangkan yang heritabilitasnya tergolong sedang adalah umur panen, diameter buah, tebal daging buah, tebal kulit buah, dan kadar gula. Bobot buah berkorelasi positif dengan diameter buah, tebal daging buah, dan tebal kulit buah. Aplikasi pemupukan KNO3 secara praktis disarankan pada genotipe melon yang memiliki respon positif terhadap KNO3.Kata kunci: kandungan gula, KNO3, kualitas buah, melon

Genetic Characterization of Turkish Snake Melon (Cucumis melo L. subsp. melo flexuosus Group) Accessions Revealed by SSR Markers

et al. 2016

Snake melon is an important cucurbit crop especially in the Southeastern and the Mediterranean region of Turkey. It is consumed as fresh or pickled. The production is mainly done with the local landraces in the country. Turkey is one of the secondary diversification centers of melon and possesses valuable genetic resources which have different morphological characteristics in case of snake melon. Genetic diversity of snake melon genotypes collected from different regions of Turkey and reference genotypes obtained from World Melon Gene Bank in Avignon-France was examined using 13 simple sequence repeat (SSR) markers. A total of 69 alleles were detected, with an average of 5.31 alleles per locus. The polymorphism information content of SSR markers ranged from 0.19 to 0.57 (average 0.38). Based on cluster analysis, two major groups were defined. The first major group included only one accession (61), while the rest of all accessions grouped in the second major group and separated into different sub-clusters. Based on SSR markers, cluster analysis indicated that considerably high genetic variability exists among the examined accessions; however, Turkish snake melon accessions were grouped together with the reference snake melon accessions.
