This study was evaluated the physiological growth response of 2 ever-bearing strawberry (Fragaria ×ananassa Duch.) cultivars for the off-season production in highland. The growth and yield of two commercial ever-bearing cultivars of ‘Pechika’ and ‘Elan’ were compared to those of a june-bearing ‘Hokowase’ cultivar. And, to develop the cropping system of ever-bearing strawberry of ‘Pechika’, this experiment was conducted in three different planting date (25 April, 25 May, and 25 June). Number of flowering cluster of ever-bearing ‘Pechika’ and ‘Elan’ cultivar were 12.7 and 12.4, respectively, but june-bearing ‘Hokowase’ was only 1. Ever-bearing cultivars showed continuous flowering habit in the higher temperature and long day condition. Soluble solids content of ever-bearing cultivars were ranged from 10.2 to 10.4 °Brix. Amount of marketable yield was produced about 19,800 ㎏ㆍ㏊-¹ in both cultivars of ever-bearing strawberry, and which was 413% higher value than that of june-bearing cultivar. Injure of mite, thrips, and powdery mildew increased with the elongation of high temperature period. The harvesting period ranged from late of June to middle of November when ever-bearing cultivars were planted at 25 April, and harvesting breaking period due to high temperature occurred once in early of August.
