“…The aforementioned, including other important crops in developing countries [e.g., finger millet (Eleusine coracana), tef (Eragrostis tef), enset (Ensete ventricosum), grass pea (Lathyrus sativus) and their wild relatives], were considered understudied [2]. Large-scale characterization of all accessions and other genetic stocks is imperative to stimulate their utilization in breeding programs [139,140].…”

The persistent challenge of insufficient food, unbalanced nutrition, and deteriorating natural resources in the most vulnerable nations, characterized by fast population growth, calls for utilization of innovative technologies to curb constraints of crop production. Enhancing genetic gain by using a multipronged approach that combines conventional and genomic technologies for the development of stress-tolerant varieties with high yield and nutritional quality is necessary. The advent of nextgeneration sequencing (NGS) technologies holds the potential to dramatically impact the crop improvement process. NGS enables whole-genome sequencing (WGS) and re-sequencing, transcriptome sequencing, metagenomics, as well as high-throughput genotyping, which can be applied for genome selection (GS). It can also be applied to diversity analysis, genetic and epigenetic characterization of germplasm and pathogen detection, identification, and elimination. High-throughput phenotyping, integrated data management, and decision support tools form the necessary supporting environment for effective utilization of genome sequence information. It is important that these opportunities for mainstreaming innovative breeding strategies, enabled by cutting-edge "Omics" technologies, are seized in Africa; however, several constraints must be addressed before the benefit of NGS can be fully realized. African breeding programs must have access to high-throughput genotyping facilities, capacity in the application of genome selection and marker-assisted breeding must be built and supported by capacity in genomic analysis and bioinformatics. This chapter demonstrates how interventions with NGS-enabled innovative strategies can be applied to increase genetic gain with insights from the Consortium of International

The members of the Aegilops genus serve as a vast pool of allele discovery for wheat improvement in abiotic and biotic stress responses. Aegilops mutica Boiss (Amblyopyrym muticum (Boiss) Eig) is an unexplored candidate with significant potential. Even though it has been used in cytogenetics applications within the last century, natural population diversity and allele discovery have been neglected. As an endemic species for Anatolia and the lower Caucasian region, it has an unexplored population structure. Here, seventy-five genotypes from five different newly collected populations from central Anatolia were evaluated with 29 polymorphic SSR loci. Significant diversity within (83%) and between (17%) the populations was obtained. Three of the populations were clearly separated, while two had some level of the mixture. Relatively easy cross-species hybridization and introgressions make Ae. mutica a good candidate for novel allele discovery and pre-breeding. Here, for the first time, representative natural populations of Ae. mutica were compared and population structures were revealed with SSR markers which may clear the misty vision that geneticists might have regarding Ae. mutica. This could be exploited in genetic resource conservation and breeding programs and maybe a point for further studies.
