| Outline of Final Research Achievements |
A new strawberry strain named T-18-2, which was bred by the
principal investigator, can be induced flower initiation, when grown under 24 hr daylength (DL) conditions with 15 to 25℃ temperature condition for 25 days. Further, the open flowers and the harvest of the fruits in the T-18-2 can be done for 30 and 60 days after finishing the 24 hr DL treatment, respectively. The purposes of the present study using the T-18-2 were, 1) to clarify the possibility for producing first fruit in approximately 60 days from the end of a 24-hour day length treatment in summer, and 2) to identify DNA marker(s) which have high linkage with the gene(s) that induce flower initiation under 24 hr day-length conditions. From the results of the experiment, it made clear that T-18-2 produced first fruit in approximately 60 days from the end of a 24-hour day length treatment. In addition, a DNA marker which had high linkage to the gene that induce flower initiation under 24 hr DL conditions.
