영문 초록

We used Cheongcheong/Nagdong doubled haploid (CNDH) genetic map to develop early flowering furthermore heavy panicle variety. Conspicuous three lines were selected among 120 CNDH population by QTL analysis two years of data on CNDH heading date and panicle weight. The casein kinase I (PCKP) gene, which is related to early heading gene, was found by physical gene mapping and map-based cloning. PCKP is involved in the control of rice flowering time by modulating the day-length response. PCKP acts as an inhibitor in the rice flowering pathway by enhancing the photoperiod response. In northern part, rice is harvested on October, however rice yield is reduce due to the frequent typhoon during September. However, if the rice varieties developed in this study are used, they can be harvested with high yield before environmental disaster, which will be efficient for safely cope with food.
