| Outline of Final Research Achievements |
A genetic linkage map of English lavender (Lavandula angustifolia) was constructed using an F1 segregating population based on AFLP and SSR markers. The linkage map was generated from 427 loci (420 AFLPs and 7 SSRs) and separated into thirty linkage groups. Thereover, the QTLs, controlling production of 9 out of 13 monoterpene compounds, were identified based on this linkage map.
Transgenic lavandin (Lavandula intermedia) plants with siRNA-inducing constract against linalool synthase (LINS) and 1,8-cineole synthase were produced. All the plants were not only inhibited production of targeted compounds as linalool and 1,8-cineole, but also reduced total essential oil production. These results suggested in existence of some genetic factors controlling total essential oil production.
