This study was conducted to develop an inbred parental line with high sugar content and yield in octoploid strawberry.‘Wongyo 3114’ was selected to have predominant horticultural traits including plant vigor, sugar content and yield amongprogenies of ‘Benihoppe’. ‘Wongyo 3114’ shows erect plant type, vigorous growth habit, early flower bud differentiation with16 flowers per cluster. Fruits of ‘Wongyo 3114’ are conical type having a bright red skin color, and 17 g in an average weight.Sugar and acidity content are similar to check cultivar, ‘Akihime’, but the firmness is lower than check cultivar. Yield isrelatively higher than check cultivar, however, its marketable yield is lower than that of check cultivar because of poorfruit-setting under low temperature condition. Disease and pest resistance of ‘Wongyo 3114’ are more sensitive and similar topowdery mildew, gray mold and two-spotted spider mites than check cultivar. Therefore, ‘Wongyo 3114’ is suitable for anintermediate parent line rather than a cultivation cultivar.
