| Outline of Final Research Achievements |
Practical use of seed-propagating strawberry cultivars needs a high seed germination percentage, as well as stable and uniform seed germination. However, seed germination in strawberry has not been genetically studied in detail. The aim of this study is identifying genetic factors involved in seed germination by segregation analyses and QTL mapping using segregating S1 population in strawberry. The results indicated that the seed germination traits in strawberry were controlled by several quantitative trait loci, and that a significant and large-effect QTL was detected on the linkage group 7A for several seed germination indexes.
