| Seedlings height of hybrids varied depending on mating combinations. Among the progenies from the mating combination, P. thunbergii(CN4)$ imes$P. densiflora(KW29) showed the best plant growth. The mean height of this combination was 521 cm at the age of 8 years(yrs), which was 9% higher than rest of the crosses. Seedlings height of progenies using P. thunbergii(JN37) as mother tree showed 28%, 33%, and 29% higher than those of open-pollinated progenies of the mother tree at the ages of 4yrs, 6yrs, and 8yrs, respectively. On the other hand, using P. densiflora (KB5) as father tree showed 45%, 48%, and 32% higher than those of open-pollinated progenies of the father tree. This result may be caused by hybrid vigor. |
