Abstract

Bred and grown around the world, tomato (Solanum spp.) has highly valuable fruits containings various anti-oxidants such as lycopene, flavonoids, glutamine, and β-carotene. Several studies have explored, way in which to enhance the growth, management and quality of tomato, we focus on the management of growth for yield rather than quality. The expression of superior agronomic traits depends on where cultivars are grown. We evaluated 10 cultivars grown in three environment for their lycopene. HTL3137 (70.48 mg·kg-1), which was grown in Yoeju in spring/summer, contained the highest lycopene content, while HTL10256 (20.9 mg·kg-1), which was grown in Suwon in spring/summer, contain the least lycopene.Correlations between color components and lycopene content varied according to growing location and season. In spring/summer-grown tomatoes from Suwon, no significant correlation was observed between any color component (redness [R], greenness [G], blueness [B], luminosity, L*, a*, b*, hue and chroma) and lycopene content. A correlation was observed between B and lycopene content in tomatoes grown in Yeoju during the same season. In tomatoes grown in Yeoju in fall/winter, significant correlations were found between lycopene content and G, luminosity, L*, and hue. Variance in interactions between genotype, environment, and genotype × environment (G × E) using Minimum Norm Quadratic Unbiased Estimate (MINQUE) analysis indicated that lycopene content depends on genotype (51.33%), environment (49.13%), and G × E (21.43%). However, when the Additive Main Effects and Multiplicative Interaction (AMMI) was used, the G × E value was highest.

토마토(Solanum spp.)는 라이코펜, 플라보노이드, 글루타민산, β-카로틴 등의 풍부한 항산화 물질을 많이 함유하고 있어 건 강채소로서 많은 주목을 받고 있다. 또한 토마토는 세계적인 작물로서 재배법 개선과 품종개량 등에서 많은 연구가 이루어 졌 으나 국내에서는 수확량에 중점을 둔 재배를 하고 있다. 따라서 우수한 형질의 특성을 가지고 있는 품종이라도 재배지역과 방 법에 따라 그 특성이 제대로 나타나지 않는 경우가 많다. 이에 10점의 품종을 이용하여 품종과 환경에 따른 라이코펜의 함량을 조사하였다.

10점의 공시재료들은 2007년부터 2014년도에 이르기 까지 농업회사 법인 현대종묘(주)에서 육성한 토마토 계통 8점과 대 조품종으로 Syngenta(Basel, Switzerland)의 Defnis와 University of Florida (Gainsville, FL, USA)에서 개발한 Tasti-Lee를 사용하였다. 라이코펜 함량은 여주지역의 봄에서 여름에 걸친 하우스 재배에서 HTL3137이 70.48 ㎎·㎏^-1으로 가장 높았으며 수원지역의 봄에서 여름에 걸친 노지재배에서 HTL10256이 20.9 ㎎·㎏^-1으로 가장 낮게 나타났다. 색 구성요소와 라이코펜 함 량의 상관관계는 재배 지역별과 유전형에 차이를 보였는데 수원 지역 봄에서 여름 기간의 노지재배에서는 뚜렷한 상관관계를 찾기 힘들었으나, 여주지역의 봄에서 여름기간에 걸친 재배에서는 B의 요인이 라이코펜 함량 상관관계를 보였으며 가을에서 겨울에 걸친 재배 작형에서는 G, Luminosity, L*, Hue의 요소가 토마토 과실의 라이코펜 함량에 영향을 주는 것으로 나타났 다. MINQUE를 이용한 유전형, 재배환경 그리고 유전형×재배환경(genotype×environment, G×E) 상호작용을 분석한 결과 라이코펜 함량을 좌우하는 변수는 유전형이 51.33%로 가장 많은 영향을 미쳤으며 환경변수가 49.13% 그리고 G×E가 21.43% 로 산출되었으나 AMMI을 이용한 분석에서는 G×E가 차지하는 요인이 가장 높았으며 유전형과 환경조건이 각각 그 뒤를 따 랐다.
