전국 차나무 자생지에서 차나무를 수집하여 조성된 클론보존원의 630클론 중 생육이 왕성하고 내한성이 높은 차나무 31계통을 선발하였다. 선발된 31계통 중 최종적으로 3계통을 선발하여 2006년부터 2008년까지 전국 6개 지역에서 지역적응성 및 영양계 비교시험을 실시하였다. 그 결과 내한성이면서 다수성을 가진 영양계 차나무 "한광"을 최종 선발하였다. "한광"은 생육이 왕성하여 새싹수는 대비품종인 야부기다에 비하여 27.6% 많았고 백아중은 47.9
The new Camellia sinensis L. variety, "Hankwang" was selected from 630 clones of the tea plant clone garden in Bioenergy Crop Research Center, National Institute of Crop Science (NICS), RDA. This variety was selected to develop superior variety for high productivity and nutrient components from 2004-2008. We evaluated the clones by the characteristics of the leaf, nutrient components, and yield. "Hankwang" was finally selected from six regional trials from 2006-2008. The number of buds and weight of "Hankwang" were better than the control cultivar "Yabukata". "Hankwang" was observed to be more resistant to cold and disease compared to the control. The nutrient components of "Hankwang" such as tannin, catechin, total nitrogen, and caffeine were 16.7, 6.08, 2.32 and 2.00%, respectively.
