Abstract:

To select the best hybrid lines, the growth, phenotypic traits and polysaccharide content of Dendrobium officinale, Dendrobium huoshanense and their F1 hybrid lines were determined and analyzed. The growth of tissue culture was significantly different in each line, in the range 0.15-0.69 g, superior to their parental strains accounting for 75.00%. The growth of the transplanting seedlings was ranged for 0.03-0.44 g, superior to their parental strains, accounting for 75.00%. Eight phenotypic traits of the tissue culture seedlings showed superior to their parents, accounting for 88.89% of the total investigation. In the transplanting seedlings, four phenotypic traits of the cultivated seedlings showed superior to their parents, accounting for 44.44% of the total investigation. The content of polysaccharides in each line was significantly different from that of their parents. The content of polysaccharides in seven lines was superior to their parents, accounting for 87.50% of the total lines studied. In summary, interspecific hybridization is one of the effective ways to improve the output and quality of Dendrobium.

Key words: Dendrobium officinale, Dendrobium huoshanense, hybridization, phenotypic character, polysaccharide
