One hundred and sixty clones of Pinus koraiensis in clone bank planted in 1983 were investigated for time of flowering, rate of flowering, and number of flowering from 1986 to 1989. The results were as follows:
1) There were clones in the minority which do not cross in natural pollination between earliest flowering female clones and latest shedding male clones. 2) The rate of male flowering appeared to be less than rate of female flowering, and to be influenced more genetically rather than the latter. 3) The number of flowering in female and male flower was affected by small number of clones. 4) The flowering number for female strobili was not related to the flowering number of male flower. 42 clones among 167 clones had no female flower. 5) The flowering number of 167 clones were classified three groups in female flower and four groups in male flower by L.S.D. 5% test. 6) The clones with abundant female and male flower were selected based on the component analysis. 7) As based on flowering rate and number of female, the juvenile phase of plus tree clones appeared to be until four years after grafting; the transition period appeared to be from five to seven years after grafting; and the adult phase appeared to begin from eight years after grafting. 8) The grafted trees showed flowering about six years earlier than seedling trees.
Key words: flowering time, flowering rate, flowering number, plus tree, Pinus koraiensis
