PROBLEM TO BE SOLVED: To provide a method for carrying out year-round culture of strawberry in which one season production variety of strawberry can be harvested over a year. SOLUTION: Flower-bud differentiation of new stock can continuously be derived in the field by continuing low-temperature short-day environment in the field. Therefore, continuous budding is made possible not only period ranging from the latter half of autumn season to spring season, but also summer season and the first half of autumn season and fruits can be harvested over year round. Temporary planting operation is made unnecessary and culture operation and culture facilities are simplified by setting the new stock separated from the parent root and keeping the new stock in the low-temperature short-day environment. Stress of roots by transplantation is eliminated, compared with a conventional culture method transplanting from temporary planting bed to the field. In addition, when the plant is set in the field without carrying out temporary planting, it is preferable that the new stock is separated from the parent root in a state in which a runner having a prescribed length is accompanied and the top of the runner is inserted into a culture medium in the field and set. Thereby, since nourishing water is supplied through the runner, high survival rate can be expected without carrying out temporary planting. COPYRIGHT: (C)2007,JPO&INPIT
