Abstract

Horse gram (Macrotyloma uniflorum (Lam.) Verdc.) is an underutilized multipurpose legume crop with inherent biotic and abiotic stress tolerance, high seed protein, dietary fiber, and micronutrients, and nutraceutical properties. However, this legume crop is lagging behind other legumes in genetic resource development and genetic improvement. Thus, this chapter highlights the global importance of horse gram in terms of its food value, nutraceutical features, and other benefits and its importance for improving soil quality, maintaining agroecological systems, and providing feed and forage for livestock sustenance. We discuss breeding approaches to enhance horse gram’s yield and biotic and abiotic stress tolerance and provide the current status of horse gram genomic resources, including a genetic map, molecular marker repertoire, QTL mapping of various traits of agronomic importance, draft genome sequence, and transcriptome assemblies. We conclude the chapter by highlighting the importance of horse gram as a climate-resilient crop and its future scope as a dietary grain legume for securing global food security.
