Zoysia matrella holding green leaves in winter and plants belonging to Eragrostoideae constructed therefrom

摘要

A series of independent technical systems including a combination of mutation methods such as cellular mutation, ultraviolet irradiation, X-ray irradiation or the like, formation and use of shoot primordium and selection of mutated cells are employed to produce genetic mutation in Manilagrass and obtain Manilagrass that retains its green leaves in winter while producing substantially no anthocyanins under normal cultivating conditions, Manilagrass that has a high stolon density, and dwarfed Manilagrass; the newly invented completely novel genotypes are used to obtain new Eragrostoideae plants.
