Pigment mutants provide excellent germplasm resources and ideal experiment materials for Porphyra genetic breedings, physiological and gene functional researches.

One important outcome of China's research into germplasm resources is hybrid rice, which was developed by scientists including Yuan Longping in central China's Hunan Province.

Research development of germplasm resources of Fructus Amomi was reviewed in the aspects of species resource, geographic distribution, intraspecies variation, and tissue culture.
