Abstract:

The new variety of Paulownia fortunei, ‘Tetraploid Paulownia fortunei 1’ was obtained through colchicines induction combined with tissue culture and clonal selection with Paulownia fortunei as the parent plant. The characteristics of this new variety are superior to its progenitor in growth, physical and chemical properties of wood, natural stem-join, and stress resistance. Its seedlings can be propagated by means of tissue culture and buried-root, and ‘Tetraploid Paulownia fortunei 1’ would be popularized in the natural distribution and cultivated areas of P. fortunei.

Key words: Paulownia fortunei, new variety, tetraploid, Tetraploid Paulownia fortunei 1
