Research Abstract	In plant, it is rare that long-day variety and short-day variety exist in the same species and strawberry (Fragaria ×ananassa Duch.) is one of such a plant. In strawberry cultivars, long-day cultivars can produce fruits through the year so this characteristic is called “everbearing". This characteristic is very important in agricultural production. Because strawberry is an octoploid plant, inheritance in strawberry is complex. Thus, we studied “everbearing" characteristic using F. vesca which is a diploid plant and model plant of Fragaria. Self- and cross-pollinated lines were bred and grown under long-day condition. Some of these lines exhibited everbearing characteristic.
