This book analyzes the biosystematics and experimental biology of five perennial genera pivotal in understanding the genetic diversity and evolutionary pathways of Triticeae, a tribe that includes essential crops like wheat, barley, and rye. It presents a revised natural classification that incorporates the latest research findings, offering a fresh perspective on the genetic diversity and evolutionary dynamics within this important group.

Key concepts covered include classical morphological taxonomy, experimental biology, and detailed taxonomic studies of each genus. The authors examine the genetic complexities of these genera, emphasizing the role of genomes like the St, Ns, and Y genomes in shaping their evolutionary trajectories. This volume highlights the importance of these genetic resources for crop improvement, particularly the Fusarium head blight resistance genes found in Roegneria.

This book is part of a series consisting of five volumes (Volumes I-V) covering taxonomy, cytogenetics, and molecular phylogeny. The series includes 30 genera, 2 subgenera, 464 species, 9 subspecies, and 186 varieties in Triticeae. Volume IV is particularly relevant for those interested in the genetic and evolutionary aspects of Triticeae, offering insights into the genetic resources that are crucial for enhancing crop resilience and biodiversity. It is

an essential resource for researchers, scholars, and students in plant sciences, genetics, and agriculture as well as a reference for biologists, plant breeders, taxonomists, geneticists, biogeographic researchers, historians, biotechnologists, agriculturalists, and evolutionists Whether you are a seasoned researcher or a student new to the field, this book provides a comprehensive and authoritative guide to the biosystematics of Triticeae, making it a valuable addition to any scientific library.

Volume I, Triticum-Aegilops complex focuses on the taxonomy and generic relationships of Triticum and Aegilops. The data concerning the origin of common wheat as a crop were also presented.

Volume II, Genera: Secale, Tritiosecale, Pseudosecale, Eremopyrum, Henrardia, Taeniantherum, Heteranthelium, Crithopsis, and Hordeum focuses on some closely related genera based on their morphological classification that contain only one unique genome.

Volume III presents perennial genera and species, including Kengyilia, Douglasdeweya, Agropyron, Australopyrum, and Anthosachne.

Volume IV presents perennial genera and species, including Stenostachys, Psathyrostachys, Leymus, Pseudoroegneria, and Roegeneria.

Volume V presents perennial genera and species including Campeiostachys, Elymus, Pascopyrum, Lophopyrum, Trichopyrum, Hordelymus, Festucopsis, Peridictyon, and Psammopyrum.
