When tea trees were introduced to Korea peninsular from China? Historically, Mr. Taeryum, an envoy of Shilla dynasty brought tea seeds from China during Tang dynasty and the seeds were planted at Jiri Mt. by the order of King Heungduk at AD828. During Koryo Dynasty(918 1392), Buddhism spread rapidly all over the country and the tea culture reached its highest stage of prosperity. At the Chosun Dynasty, however, the ceremonial drinking of tea vanished almost completely due to the flourishing Confucian tradition, a kind of substitution of Buddhism. But a few people have supported the traditional tea culture by themselves. Since the independence of Korea soon after the World War II at 1945, Korean War have been exploded at 1950. After economic evolution have been succeeded at 1980, the cultivation area of tea trees has been increased about 2,000ha and the cultural tradition of tea drinking has become popular again at a tea consume quantities amounted to 100g per capita at 2004. The northern limited area of tea plant is lined on the southern part of Korea peninsular. It is very small region compared to China about one million ha and to Japan over 60 thousand ha. It is problem not only the area of tea fields but also the methodology of tea cultivation, for examples without clonal cultivars and mechanical systems. WTO treatments was discussing with Korea, China and Japan government at 2005. Green tea custom is very high at 514% in Korea. If three countries will be agreed the imported tax will be cut off, the Korean tea farmers will be confused because of unstable situation of tea markets. All most of tea farmers should be made the tea fields by seeding not clonal propagation. Because of clonal cultivars have not developed in Korea, there have not been the research institutes for tea plants and manufactures before 1992. Now there are three research institute of tea in Korea; Tea Experiment Station at Bosung of Jeonnam Agricultural Research & Extension Services, Mokpo Experimental Station of National Institute of Crop Science, and Green Tea Cluster Institute of Hadong. Mokpo and Hadong Research Station were established at 2004 and at 2005 but Bosung Station was established at 1992. Seven clonal tea cultivers were selected at Bosung Station; Bohyang, Myngsun, Chanlok, Sunhyang, Mihyang, Jinhyang and Ohsun until 2004. Mokpo Experimental Institute was started the tea provenance testing about 4 provenances: Kangwon-do, Jeonlabuk-do, Jeonlanam-do, and Kyungsangnam-do. Korean new tea cultivers should be selected because Koran wild tea population have been high genetic variation. If tea breeding research will be successful to select new clonal cultivers, the tea farmers of Korea will be stable after WTO treatment with each country.

농촌진흥청 국립원예특작과학원에서는 2003년 분홍색의 스프레이 장미 ‘Pinocchio’과 다화성인 황색의 스프레이 장미 ‘Flair’품종을 교배하여 얻은 실생계통으로부터 2006년부터 2008년까지 3년동안 특성검정을 실시한 후 절화장이 길고, 수량이 많은 ‘레몬티’ 품종을 육성하였다.‘레몬티’는 밝은 황색(RHS Y155A)의 화색으로 꽃잎수는 52.3개, 화폭은 5.1 cm인 스프레이 품종으로 년간 절화수량은 153본/m2으로 대비품종 ‘써니레이디’보다 많았으며 절화장은 70.3 cm 절화경경은 5.7 mm로 절화특성이 우수했다. 소화수는 ‘써니레이디’의 4.2개보다 많은 6.5개를 보여 우수한 스프레이 형태를 지닌 절화장미로 평가되었으며 절화수명은 13.0일로 ‘써니레이디’보다 길었다.

2003년도에 오렌지색의 스프레이 'Pinocchio' 품종을 모본으로 다화성인 황색의 스프레이 'Flair' 품종을 부본으로 인공교배 하였다. 2004년부터 2005년까지 파종을 실시하여 177개체의 실생을 획득하여 이들을 대상으로 2006년부터 2008년 까지 3차에 거쳐 특성검정을 실시한 후 최종 특성검정 단계에서 기호도 조사를 실시한 결과 최종선발된 '원교 D1-506'을 2008년 농촌진흥청 농작물 직무육성 신품종 선정위원회를 거쳐 '체리티'로
