'Kumaken-i-548' is a new strawberry cultivar selected from hybrid seedlings between '98-30' and '98-20-3'. This crossing was carried out in 2000 to obtain a high performance cultivar for forcing culture in Kumamoto prefecture. The characteristics of this cultivar are described here. 'Kumaken-i-548' is vigorous and upright. The leaves are green or dark green and the number of flowers in the terminal cluster is eight on average. The gibberellin treatment is needless because the peduncle elongates well. Lighting is needless because the top does not dwarf. Similar to 'Sachinoka' and later than 'Toyonoka', the flower bud of the terminal cluster is initiated in the middle or the latter part of September. The fruits are as large as eighteen grams and they are larger than 'Toyonoka'. The fruits are conical and very shiny cherry red. The sugar content is high, and the fragrance is good through the harvest season, and it is very delicious. As for the fruit, the flesh is hard in comparison with 'Toyonoka', but the rind is soft. This cultivar has no disease resistance and is more susceptible to anthracnose than 'Toyonoka'. 'Kumaken-i-548' is suitable for forcing culture in Kumamoto prefecture.
