Abstract
The paper presents descriptions of three new botanical varieties of the type subspecies of durum wheat (Triticum durum Desf. subsp. durum), namely Triticum durum subsp. durum convar. durum subconvar. muticum (Orlov) Dorof. et Filat. var. muticomelanopus Lyapun.; T. durum Desf. subsp. durum convar. caucasicum (Dorof.) Dorof. var. cauafricanum Lyapun.; and T. durum Desf. subsp. durum convar. caucasicum (Dorof.) Dorof. var. muticocauafricanum Lyapun.). Also, three new forms are described: T. durum Desf. subsp. durum convar. durocompactum Flaksb. var. rubrinigrum (Stol.) Dorof. et Filat. f. tristerubrinigrum Lyapun.; T. durum Desf. subsp. durum convar. falcatum (Jakubz.) Dorof. et Filat. var. falcatileucomelan Dorof. et Filat. f. tristefalcatileucomelan Lyapun.; and T. durum Desf. subsp. durum convar. caucasicum (Dorof.) Dorof. var. caumelanopus Lyapun. f. tristecaumelanopus Lyapun.). The nomenclatural types of new taxa have been transferred to the Herbarium of Cultivated Plants of the World, their Wild Relatives and Weeds (WIR).
Supporting agencies: The present work was performed within the framework of the State Assignment to VIR No. 0662-2019-0006 “Disclosing the scientific potential of the VIR herbarium collection as a specific unit of global agricultural biodiversity conservation for the scientifically substantiated mobilization, effective study and conservation of the genetic diversity of cultivated plants and their wild relatives”. The author is grateful to the staff of the Department of Agrobotany and Genetic Resources in situ Conservation for their help in preparing the illustrations.
