 note = {One-year-old apple trees of seven selections of columnar-type growth characteristics on grafted Marubakaido (Malus. prunifolia Bork. var. ringo Asami） and those of 'Fuji' on grafted M.9EMLA were planted at National Institute of Fruit Tree Science in Morioka, Japan to evaluate tree growth, flower bud formation and fruit productivity. In regard to tree growth, selections of six-year-old seven columnar-type apple trees showed the typical columnar tree shape with tree width of 54 cm to 78 cm. Tree heights were extremely different, varying from 1.8 m to 4.6 m. The tree canopy area per six-year-old apple tree ranged from 0.2 m^2 to 0.6 m^2, and tree volumes were from 0.6 m^3 to 2.6 m^3. Great differences in trunk cross-sectional area, the number of shoots with a length of more than 10 cm and total shoot length were also observed among the selections of columnar-type apple trees. Although all columnar-type apple trees studied were more compact than 'Fuji', the degree of compactness and branching pattern were different depending on the selections of the columnar-type apple trees. Seven columnar-type apple trees showed the differences in the number of flower buds, and tendency of alternate bearing characterwas emphasized in the selections with many flower buds. The fruit yield of the selections of columnar-type apple trees increased gradually after bearing as three- or four-year-olds, buttotal  fruit yield of the seven columnar-type apple trees were lower than that of 'Fuji'. The fruit productive efficiency per the trunk cross-sectional area of the seven columnar-type apple trees was lower than that of 'Fuji'. Great differences were observed in fruit productive efficiency per tree canopy area or tree volume. The fruit productive efficiency of most of the columnar-type apple trees was higher than those of 'Fuji' in the year with many fruits, and some columnar-type apple trees had almost same efficiency as 'Fuji' in the year with few fruit. The fruit of columnar-type apple trees were small, with low Brix % and high acid compared to the 'Fuji'. In conclusion, it is considered that apple trees with columnar type growth habit were worth for the reduction of labor in orchards. Therefore, improvement of cultivated managements and back-crossing of the present columnar-type apple trees should be important issues.},
