Progress report on the study of Psathyrostachys huashanica and its application to wheat improvement

doi:10.11686/cyxb20140539

Abstract

Abstract:

Psathyrostachys huashanica is an endangered wheat-related species found only on Mount Hua of the Qinling Mountains in the Shaanxi Province of China. It is considered an important germplasm resource for broadening genetic diversity and for developing new cultivars due to its valuable resistance to cold, drought and diseases. This paper reviews existing literature on the species. Most studies have focused on the taxonomy of the biological traits of P. huashanica, its evolution and population ecology. A number of studies have considered its usefulness as a resource for genetic improvement, including how to identify and develop new intermediate plants through crossings with wheat. The paper concludes with a general discussion of the ecological protection of P. huashanica and the species’ application in plant breeding so that new knowledge can be discovered and utilized effectively in practice.
