“…Genetic diversity can be achieved using landraces and wild species in conventional breeding as sources of valuable traits for wider adaptability, including traits related to biotic and abiotic stress resistance ( Nyongesa et al, 2013 ; Teklu et al, 2022 ). Sesame includes more than 37 species distributed across Africa, Asia, and Australia, with different chromosome numbers and features ( Nayar and Mehra, 1970 ; Yadav et al, 2022 ). The ploidy level of S. indicum and S. radiatum are expressed as 2 n = 26 and 2 n = 64, respectively ( Nayar and Mehra, 1970 ).…”

“…The somatic chromosome numbers of some wild species of sesame include S. lanciniatum at 2 n = 28 and S. angolase and S. prostratum , at 2 n = 32, and S. occidentale , at 2 n = 64 ( Hegde, 2012 ). Other species include S. triphyllum , and S. capense , with 2 n = 26, S. angustifolium , with 2n = 32, and S. prostratum and S. schinzianum , with 2 n = 64 ( Yadav et al, 2022 ). Therefore, sesame has species with various ploidy levels, including diploid ( S. indicum , S. triphyllum , and S. capense , where 2 n = 2 x = 26), tetraploid ( S. angustifolium , S. angolase , and S. prostratum , where 2 n = 32), and octaploid ( S. occidentale , S. radiatum , and S. schinzianum , where 2 n = 8 x = 64).…”

“…Improving plant height and developing sesame genotypes with determinate growth habits would solve these problems. Yadav et al (2022) also suggested that genes and genotypes associated with determinate growth and monocular stems would be important for mechanized sesame harvesting. Therefore, the identification of such genes, genotypes, QTLs, and other genomic regions of sesame related to sesame architecture is important.…”

“…Sesame plants are mainly affected by biotic stress induced by bacteria, fungi, viruses, insect pests, and nematodes ( Yadav et al, 2022 ), which can cause highly reduced sesame quality and yield. The major diseases of sesame include various bacterial, fungal, and viral agents, including Cercospora sesami , Alternaria sesami , Cylindosporium sesami , Macrophomina Phaseoli , Phytophhthora parasitica , oidim spp , Erysiphe cirhoracearum , Phytophthora nicotianae var.…”

Sesame (Sesamum indicum L.) is an ancient diploid oilseed crop with high oil content, quality protein, and antioxidant characteristics that is produced in many countries worldwide. The genes, QTLs, and genetic resources of sesame are utilized by sesame researchers and growers. Researchers have identified the many useful traits of this crop, which are available on different platforms. The genes, genotypes, QTLs, and other genetic diversity data of sesame have been collected and stored in more than nine genomic resources, and five sesame crop marker databases are available online. However, data on phenotypic and genotypic variability, which would contribute to sesame improvements, are limited and not yet accessible. The present study comprehensively reviewed more than 110 original published research papers and scientifically incorporated the results. The candidate genes, genotypes, and QTLs of significantly important traits of sesame were identified. Genetic resources related to grain yield and yield component traits, oil content and quality, drought tolerance, salt tolerance, waterlogging resistance, disease resistance, mineral nutrient, capsule shattering resistance, and other agronomic important traits of sesame were studied. Numerous candidate genotypes, genes, QTLs, and alleles associated with those traits were summarized and discovered. The chromosome regions and linkage groups, maps associated with the best traits, and candidate genes were also included. The variability presented in this paper combined with sesame genetic information will help inform further sesame improvement.

Globally, the gap between the production of nutritious quality crops and their consumption is widening, resulting in high rates of malnutrition and micronutrient deficiencies. Our goal is to examine the rich tapestry of studies on underutilized crops (UUCs) and consider their potential role in alleviating food and nutritional insecurity. Published research articles on UUC were retrieved from databases, such as Web of Science, Google Scholar, and Scopus. The key terms used were “UUC,” “neglected crops,” and lists of UUC, which were frequently cited in literature. A bibliometric innovative approach, such as reference co‐citation, co‐citation, and co‐word analysis, was used. We observed an annual growth rate of 6.4% in UUC research outputs with the number of annual publications increasing from less than 700 article publications in 2000–3000 article publications in 2021. It is also developing into a noticeably interdisciplinary research field with more collaborations and institutional affiliations. The most relevant affiliated countries in UUC‐related studies are developed and transition countries, such as the United States of America, China, India, the United Kingdom, South Africa, Australia, and Germany. The pressing and emerging research studies in UUC‐related studies are genetic diversity and identification, agronomic knowledge, seed improvement, and environmental stresses. There is a shift in the focus of UUC studies, which provides a deeper understanding of the global trends and directions that have evolved in UUC studies over the past two decades. This result provides researchers and policymakers in the field of UUC with a useful tool for decision‐making on UUC.

Sesame (Sesamum indicum L.) is an ancient oilseed crop belonging to the family Pedaliaceae and a globally cultivated crop for its use as oil and food. In this study, 2496 sesame accessions, being conserved at the National Genebank of ICAR‐National Bureau of Plant Genetic Resources (NBPGR), were genotyped using genomics‐assisted double‐digest restriction‐associated DNA sequencing (ddRAD‐seq) approach. A total of 64,910 filtered single‐nucleotide polymorphisms (SNPs) were utilized to assess the genome‐scale diversity. Applications of this genome‐scale information (reduced representation using restriction enzymes) are demonstrated through the development of a molecular core collection (CC) representing maximal SNP diversity. This information is also applied in developing a mid‐density panel (MDP) comprising 2515 hyper‐variable SNPs, representing almost equally the genic and non‐genic regions. The sesame CC comprising 384 accessions, a representative set of accessions with maximal diversity, was identified using multiple criteria such as k‐mer (subsequence of length “k” in a sequence read) diversity, observed heterozygosity, CoreHunter3, GenoCore, and genetic differentiation. The coreset constituted around 15% of the total accessions studied, and this small subset had captured >60% SNP diversity of the entire population. In the coreset, the admixture analysis shows reduced genetic complexity, increased nucleotide diversity (π), and is geographically distributed without any repetitiveness in the CC germplasm. Within the CC, India‐originated accessions exhibit higher diversity (as expected based on the center of diversity concept), than those accessions that were procured from various other countries. The identified CC set and the MDP will be a valuable resource for genomics‐assisted accelerated sesame improvement program.
