Objective A new high-quality, high-yield Dendrobium officinale variety suitable for cultivation in Fujian was bred.
Method The capsules of D. officinale were obtained from natural pollination of L-2, a wild species found at Guanzhaishan in Liancheng County. From the offspring seedlings, LF-9 with the most desirable agronomic traits, growth potential, and stem yield was selected and rapidly propagated in tissue culture.
Result After years of experimental cultivations at various localities, LF-9 excelled L-2 （CK） in quality evaluation, by microstructure observation, and with molecular identification. It was named Fuhu 1 and rendered in two-year regional tests an average fresh stem yield of 4,77 7.5 kg·hm-2, which was 17.7% higher than that of CK. At harvest, merely 0.9% of the plants were infected by the blight disease. The infection rate was 50.0% lower than that of CK. For the black spot disease, the occurrence rate was 7.3%, which was 29.8% lower that of CK. On the contents of functional ingredients, Fuhu 1 contained 51.8% polysaccharides, i.e., 8.8% higher than CK, and 15.3% alcohol soluble, i.e., 82.1% higher than CK.
Conclusion D. officinale var. Fuhu 1 was certified by the Committee of Identifying Variety in Fujian Province in 2016 （Fujian Medicine No. 2016001）. It was a superior variety with highly desirable agronomic properties including high yield, high quality, and strong disease resistance and considered a promising new D. officinale for commercial cultivation in Fujian.
