The investigation on the morphological and genetic relationship was carried out with leaves of teas(Camellia sinenesis L.) which were collected from 16 southern areas of Korea including one Japanese location: Hadong, Sachun, Gosueng, Namhae, Milyang, Gimhae, Busan, Jinju, Yangsan, Gurye, Suncheon, Boseong, Gangjin, Haenam, Jeju and Shizhuoka(Japan). In the analysis of genetic relationship, RAPD analysis was done with 30 primers purchased at Bioneer company. There were 80 expanded bands totally observed and 58 bands were found to have polymorphism. The size of expanded DNA was between 200bp and 2,000bp. For the analysis of genetic relationship, NTSYS computer program was used and the similarity value among domestic green teas was 0~0.09. With the similarity value matrix, 12 groups were formed as a result of 16 kinds of dendrogram. The similarity value was so high between Sachun and Gosueng, and between Gurye and Suncheon as 0.90. In the cases of Sachun and Gosueng, there was no difference in leaf length, leaf shape, and leaf width (data not shown) indicating the presence of coincidence between RAPD analysis and morphological analysis. However, in the cases of Gurye and Suncheon, morphological characteristics was not coincident with DNA analysis where both collections belong to same group. Using the polymorphic bands which has a distinct presence or absence in RAPD analysis, the SCAR marker was constructed. Among the 5 SCAR markers, only one from RAPD marker #4 showed a single amplification of 868bp indicating low efficiency of transformation rate from RAPD marker to SCAR marker. But removal of all multiple bands in SCAR amplification clearly revealed that SCAR marker is repetitive and reliable in the amplification of polymorphic DNA region.

Ganjin Dawon tea leaves showed the heaviest weight of dry and fresh tea leaf (0.30 g and 0.79 g, respectively), whereas IlJi Am showed the lightest weight of dry and fresh tea leaves (0.04 g and 0.14 g, respectively). Regarding the correlation between the characteristics of the tea leaves, the weight of the dry leaves, which represents the quantity, showed high degree of significance with the leaf length, leaf width, leaf area and, weight of fresh leaves. The leaf area , which represents the quality, showed astrong correlation with the leaf length (0.986**) and leaf width (0.985**).

As a result of analysis, Wu-yi has the highest value in leaf length (9.45 cm), width (3.88 cm), and area (25.84 cm2) and it also has the highest weight value of dry (0.38 g)/fresh (0.71 g) leaf. Asanoka has the highest value in leaf stalk length as 0.61cm, Taiwan tea (Daecha No. 21) has the largest value in the number of serrate as 21.60 while Jeju No.1 has the largest value in the number of vein as 9.80. Jeju No. 2 has the lowest value in leaf length (6.65 cm), width (2.25 cm), area (10.6 cm2), and the number of serrate (15.07) as well as it has the lowest weight value of dry (0.07g)/fresh (0.28 g) leaf while Jeju No.1 has the lowest value in leaf stalk length (0.16 cm). Taiwan tea (Daecha No.21), Mayryoku, and Asanoka have the same value in the number of vein (7.07) as the lowest value. As a result of analysis for heritability, genetic variance and environmental variance of tea leaves, the values of genetic variance are higher than the values of environmental variance in all the traits. The value of genetic variance is the highest in leaf area as 23.4734 as well as the value of environmental variance is the highest in leaf area as 5.0496, However, the value of environmental variance tended to lower overall. The value of heritability is the highest in leaf stalk length as 99.95%, the weight value of dry leaf, leaf width in order. The value of heritability is high as more than 70% in all the traits and therefore it would be easy to select superior traits.

남부 산간지역에서 수집한 차나무 삽수의 특성 및 삽목 후 활착율 : 지리산을 중심으로

이용호(Yong-Ho Lee),강달순(Dal-Soon Kang),오주성(Ju-Sung Oh),제순자(Soon-Ja Je),김성만(Sung-Man Kim) 한국차학회 2011 한국차학회지 Vol.17 No.2

The conclusion of hierarchical characteristics and multiplication for cutting grafting with tea having dominant trait among wild teas (Camellia sinensis L.) collected from southern mountainous region is as below. Although tea leaves collected from Jigoksa area in Sancheong and Dosimdawon area in Hadong are narrow in leaf width and distinct in vein and serrate, tea leaves collected from Chabatgol area in Gimhae and Dasolsa area in Sacheon are generally large in leaf size and indented in vein and serrate. In addition, the leaves from Chabatgol and Dasolsa area as secondly mentioned above have high performance in rooting rate (97.0-100%) and are high worth their keep as a model of crossbreeding for the future because their genetic trait that has the highest correlation with leaf area representing qualitative character is the leaf width (0.882**).

경상남도 서부 산간지인 하동, 사천, 고성, 남해, 밀양, 진주와 전라남도의 구례, 순천 등 8개 지역에서 수집한 종자를 증식시킨 차나무 중에서 잎 특성이 다른 계통을 선발하여 보존 중인 6년생 차나무의 잎 형태별 특성을 조사하였다. 차나무 잎의 형태별 특성 중 신초장은 15.4㎝에서 23.8㎝로 적갈색광타원형 잎이 적갈색피침형 잎보다 7.5㎝나 더 길었고, 엽장(葉長)의 경우 5.1㎝에서 11.5㎝로 평균 7.4㎝이였으며, 이중 적색광타원형 잎이 가장 길었고 적갈색피침형, 갈색소타원형, 암갈색타원형 잎이 5.1㎝로 가장 짧았다. 엽폭(葉幅)은 전체 평균은 3.1㎝로 적색광타원형 잎이 5.7㎝로 가장 넓게 나타났으며, 적갈색피침형 잎이 2.0㎝로 가장 짧았다. 엽면적(葉面積)은 7.2㎠에서 45.5㎠로 평균 17.0㎠ 이었고, 적색광타원형 잎이 가장 넓게 나타났으며, 적갈색피침형 잎이 다른 계통에 비해 작게 나타났다. 엽병장(葉柄長) 평균은 0.4㎝였으며, 적색 장 타원형 잎과 적갈색 장타원형 잎이 0.6㎝로 가장 길었고, 녹색타원형 잎이 0.3㎝로 가장 짧게 나타났다. 거치수(鋸齒數)는 평균은 28.4개였으며, 황색타원형차가 35.0개로 가장 많았고, 갈색소타원형과 적갈색피침형 잎이 24.0개로 가장 적었다. 평균 엽맥수(葉脈數)는 8.8개였으며, 황색타원형 잎이 11개로 가장 많았고 적갈색 장타원형 잎이 7개로 다른 지역에 비해 가장 적게 나타났다. ㎡당 신초수는 평균 988개이었으며, 이중 갈색소타원형 잎이 1,474개로 가장 많았고, 녹색광타원형 잎이 370개로 가장 적었다. 백아중은 평균 41.62g이었으며, 신초수가 적은 녹색광타원형 잎에서 84.58g으로 매우 무거웠고 적갈색피침형 잎에서 22.88g으로 가장 가벼웠다. ㎡당 생엽중(生葉重)은 최저 15.08g에서 최고 60.24g으로 평균은 30.97g 이었으며, 녹색광타원형 잎에서 60.24g으로 가장 많았으며, 가장 적은 것은 녹색소타원형 잎으로 15.08g이었다. 차나무 계통별 형질 상호간의 상관계수는 유전상관계수 값이 표현형 상관계수 값에 비해 대체적으로 높은 경향을 보였고, 각 형질상호간의 유전상관계수나 표현형 상관계수는 모두 정(+)으로 나타났다. 차나무 잎의 형질간 상관관계는 수량성을 나타내는 건엽중은 엽장, 엽폭, 엽면적, 생엽중과 고도의 유의성을 보였으며 0.8이상의 매우 높은 유의차를 보였다. 본 연구 결과 엽장(葉長), 엽폭(葉幅) 및 엽면적(葉面積)은 적색광타원형 잎이 가장 크고 많았으며, 백아중과 생엽중은 녹색광타원형 잎이 가장 무거웠으나 신초수가 다소 적었다. 엽장(葉長), 엽폭(葉幅) 및 엽면적(葉面積)이 낮고, 백아중이나 생엽중이 적은 적갈색피침형이나 갈색 소타원형 잎은 금후 차나무 육종 재배모본이나 관상수로개발 가치가 높을 것으로 판단된다. For the purpose of research, tea leaves with different morphological characteristics were selected from tea plants, those seeds that have been collected from the mountainous areas of the central southern area of Mt. Jiri in Korea namely the eight different regions of Hadong, Sacheon, Goseong, Namhae, Miryang, Jinju, Gurye, and Suncheon. After that leaf characteristics of 6-year old tea trees were examined and compared. Among the characteristics of tea trees, genotype coefficients tended to be higher regardless of phenotype coefficients. Both genotype coefficients and phenotype coefficients among characters were shown to be positive. Dry leaf weight which is quantitative showed a high degree of significance with leaf length, leaf width, leaf area, and fresh leaf weight, and showed very high significant difference of larger than 0.8
