| Outline of Final Research Achievements |
We characterized vernalization requirement of 49 strains of oilseed rape, and developed the F2 population of Isuzu-natane (low vernalization requirement) × synthetic B. napus (strong vernalization requirement ). In addition, we developed a line that was introduced the region containing BoFLC 2 region derived from cabbage into the top of chromosome 2 of Chinese cabbage. We showed that the differences of expression level of BrFLC 1/2/3 in cabbage and Chinese cabbage may be related to the diversity of vernalization requirement in cabbage and Chinese cabbage cultivars. The RNA-seq analysis revealed that long non coding RNA was expressed on BoFLC2 locus by low temperature treatment. Our developed Chinese cabbage line showed delay of flowering in the winter cropping pattern, compared with ordinary Chinese cabbage cultivars, indicating that it can be used as a breeding material.
