194 plantlets regenerated from leaf explants of boxthorn 'Cheonyang' were cultivated to investigate their morphological characteristics in the field for 2 years. Based on the morphology of leaves, 66.1% of them had elliptical type leaf, the same as that of mother plants, while 22.2% in oval type, 7.2% in obovate type, 2.6% in long-obvate type and 2.1% in lanceolate type. They were classified to 4 groups; group A was selected with both high fruit size and fruit yield, group B with only high fruit size, group C with larger or thicken leaf, and group D with multiple brenches. In comparision of production efficiency between the selected groups and mother plants, group A (99741, 99781, 99854, 99870 and 99886) were longer (2.1 to 2.7 mm) in length of fruits and higher in fruit production (15 to 30%) as compared to mother plants. Croup D (99797 and 99892) was higher in leaf production (7.2%) as compared to boxthorn 'CL1-48', which is the highest in leaf production among boxthorn veriaties.
