It also provides extensive information on the nutritive value of underutilized pseudo-cereals, the goal being to broaden the vegetable list. Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants. Most of the species are summer annual weeds and are commonly referred to as pigweed. Only a few are cultivated as vitamin-rich vegetables and ornamentals. The protein-rich seeds of a handful of species, known as grain amaranths, are consumed as pseudo-cereals. Amaranthus manifests considerable morphological diversity among and even within certain species, and there is no general agreement on the taxonomy or number of species. Currently the genus Amaranthus is believed to include three recognized subgenera and 70 species. Amatanthus is considered to potentially offer an alternative crop in temperate and tropical climate. The classification of amaranths is ambiguous due to the lack of discrete and quantitative species-defining characteristics and the wide range of phenotypic plasticity, as well as introgression and hybridization involving weedy and crop species. It is a known fact that both vegetable and grain amaranths have evolved from their respective weed progenitors. There are more than 180 different weed species that are herbicide-resistant, and amaranths are considered to be leading members of the resistant biotypes. Amaranth species provide ample scope for investigating herbicide resistance mechanisms. Amaranths also show variability in terms of their mating behavior and germplasm, adaptability to different growing conditions, and wide range of variability in sexual systems, from monoecy to dioecy. A solid grasp of these parameters is essential to the future utilization of amaranths as super crops. There are quite a few amaranth research center and germplasm collections all over the world that maintain and evaluate working germplasms. To date, the genetic improvement of amaranths has primarily involved the application of conventional selection methods. But advances in genomics and biotechnology have dramatically enriched the potential to manipulate the amaranth genome, especially improving the amount and availability of nutrients. In conclusion, the book covers all aspects of amaranths, including their food value, significance as vegetables and pseudo-cereals, taxonomy, phylogeny, germplasm variability, breeding behavior and strategies, cultivation practices, and variability in terms of their sexual systems. It offers a valuable resource for all students, researchers and experts working in the field of plant taxonomy and diversity. 606 $aPlant systematics 606 $aPlant taxonomy 606 $aPlant breeding 606 $aPlant physiology 606 $aAgriculture 606 $aPlant Systematics/Taxonomy/Biogeography$3https://scigraph.springernature.com/ontologies/product-market-codes/L24051 606 $aPlant Breeding/Biotechnology$3https://scigraph.springernature.com/ontologies/product-market-codes/L24060 606 $aPlant Physiology$3https://scigraph.springernature.com/ontologies/product-market-codes/L33020 606 $aAgriculture$3https://scigraph.springernature.com/ontologies/product-market-codes/L11006 615 0$aPlant systematics. 615 0$aPlant taxonomy. 615 0$aPlant breeding. 615 0$aPlant physiology. 615 0$aAgriculture. 615 14$aPlant Systematics/Taxonomy/Biogeography. 615 24$aPlant Breeding/Biotechnology. 615 24$aPlant Physiology. 615 24$aAgriculture. 676 $a578.012 676 $a578.09 700 $aDas$b Saubhik$4aut$4http://id.loc.gov/vocabulary/relators/aut$01063608 906 $aBOOK 912 $a9910253907003321 996 $aAmaranthus: A Promising Crop of Future$92533171 997 $aUNINA
