“…Utilizing wild agrestis germplasm to broaden the genetic diversity of melon and integrate it into resistance breeding is crucial (Dhillon et al 2012;Choudhary et al 2020). Our study revealed a limited genetic exchange between subspecies melo and subspecies agrestis germplasm, suggesting the underutilization of wild agrestis germplasm in sweet melon improvement efforts.…”

A total of 96 melon germplasm from four horticultural groups were undertaken for genetic characterization using 107 microsatellitemarkers. The average diversity indices of microsatellite markers, viz., allele number, major allelic frequency, gene diversity, expectedheterozygosity and polymorphic information content, were 2.69, 0.84, 0.25, 0.06 and 0.22, respectively. The neighbor-joining dendrogramgrouped the melon germplasm into four major clusters with distinct separation of Indian reticulatus germplasm from that of the exoticgermplasm adapted in India and wild agrestis germplasm. Population structure analysis deciphered two main subpopulations broadlycorresponding sweet melon preferred by consumers from sub-species melo and non-sweet wild agrestis melon separately along withadmixtures. This finding was validated by principal coordinate analysis. AMOVA analysis further partitioned the whole genetic variationamong individuals (74%), within individuals (22%) and among populations (4%) with low genetic differentiation and high levels of geneflow among subpopulations. A total of 12 microsatellite markers produced 19 unique alleles among 24 germplasm, which would actas a distinct DNA fingerprint for germplasm identification and legal protection. The present study provided a deeper understanding ofthe genetic structure of melon germplasm and will assist in formulating future breeding programmes.

“…Genetic linkage maps and molecular markers for the QTLs of horticultural traits in melons identified in previous studies are briefly reported in Table 1. Furthermore, the identification of large numbers of single nucleotide polymorphisms (SNPs) using whole-genome resequencing (WGRS) has facilitated the rapid identification and definition of candidate genomic areas for fruit quality attributes in melons [17]. Comparative genomic analysis has also been used to identify functional genes that govern both the qualitative and quantitative phenotypic traits of melons [18].…”

Melon (Cucumis melo L.) is an important crop that is cultivated worldwide for its fleshy fruit. Understanding the genetic basis of a plant’s qualitative and quantitative traits is essential for developing consumer-favored varieties. This review presents genetic and molecular advances related to qualitative and quantitative phenotypic traits and biochemical compounds in melons. This information guides trait incorporation and the production of novel varieties with desirable horticultural and economic characteristics and yield performance. This review summarizes the quantitative trait loci, candidate genes, and development of molecular markers related to plant architecture, branching patterns, floral attributes (sex expression and male sterility), fruit attributes (shape, rind and flesh color, yield, biochemical compounds, sugar content, and netting), and seed attributes (seed coat color and size). The findings discussed in this review will enhance demand-driven breeding to produce cultivars that benefit consumers and melon breeders.
