I. INTRODUCTION

Planting materials are one of the most important factors in forestry production. In recent years forest tree improvement in our country has been given attention . Some results from research on species and provenance trials as well as breeding have been, , put into practice step by step. However, forest tree breeding work , in general, still has many limitations.

The subject en titled ” Research on formulation of scientific and technological basis for supplying improved planting materials of forest trees” is aimed at improving material quality for the main planting tree species and progressively increasing plantation productivity in our country.

Main contents of the research were:

– Species and provenance trials

– Plus tree selection

– Progeny test

– Establishment of seed production areas and seed orchards

– Tissue culture

– Cutting propagation.
