Abstract

The invention discloses a seed selection method of E. urophylla*E. Grandis clone DH30-1. The method comprises the following steps: firstly, a female parent Eucalyptus urophylla U16 and a male parent Eucalyptus grandis G22 are taken as parents, and subjected to castration, bagging, pollen collection, artificial pollination, bag removing, seed collecting, seeding and seed selection to obtain the E. urophylla*E. Grandis clone DH30-1 with consistent characters, stable inheritance and not subjected to character segregation. The E. urophylla*E. Grandis clone DH30-1 has the characteristics of fast growth, high yield, short rotation (industrial fiber material is adopted), straight stem form, small branches, neat forest phase, good material property, straight texture, good barrenness resistance, and capability of being suitable for being planted in large-area regions.
