본 연구는 베트남 하노이 지역에서 8가지 한국 토마토 품종 (핑크탑, 큐피랑, 슈퍼도태랑, 선레드, 선글러브, TP-7 플러스, 러블리 250, 광복)과 1가지 베트남 품종(FM 120)을 대상으로 봄-여름 및 가을-겨울 작기에 따른 수확량 및 과실 특성을 비교 분석하였으며, 그 결과는 다음과 같다.
1. 작기에 따라 초장, 경장, 주당 과실수 및 수확량(kg)은 유의성이 있었으며 가을-겨울 작기에서 높게 나타났다. 전체적으로 한국품종이 베트남 품종에 비해 높은 생육특성을 보인 반면, 과실수와 수확량에서는 베트남 품종이 우수하였다.
2. 토마토 과실의 주요 특성인 과장, 과폭 및 과중은 작기에 따라 유의한 차이를 보였으며 가을-겨울 작기에서 높은 수치를 나타내었지만 TSS 함량은 봄-여름 작기에서 높았다. 건물중과 비타민C 함량은 작기에 따라 유의한 차이가 없었다. 품종별 과실 특성은 한국 품종이 우수하였지만 비타민C 함량은 베트남 품종이 높았다.
3. 봄-여름 작기에서 한국품종의 경우 수확량 및 과실특성에서 가을-겨울 작기 재배에 비해 큰 감소를 보인 반면 베트남 품종은 큰 차이를 보이지 않았다. 따라서 본 실험에 이용된 8가지 한국 품종의 경우 봄-여름 작기보다는 가을-겨울 작기 재배가 적합할 것으로 판단된다.

This study was conducted to investigate the yield and fruit characteristics of Korean tomato (Lycopersicon esculentum Mill.) cultivars in two different cropping seasons (February 2011 to February 2012) in Hanoi, Vietnam. The experiment was arranged in a completely randomized block design, with three replications. Eight Korean cultivars, specifically, ‘Pink Top’, ‘Kyupirang’, ‘Super Dotaerang’, ‘Sun Red’, ‘Sun Glove’, ‘TP-7 Plus’, ‘Lovely 250’, and ‘Gwangbok’, and one Vietnamese cultivar, ‘FM 120’, were transplanted in an open field in March (spring-summer) and October (fall-winter) of 2011. The cropping season significantly affected the plant height (cm), stem diameter (mm), fruit (no.) and total yield (kg) per plant, fruit length (cm) and width (cm), fruit weight (g) per plant, and total soluble solids (TSSs, °Brix). However, the dry weight (%) and vitamin C (mg/100 g) content showed no significant differences in the different cropping seasons. The highest values for the growth and fruit characters of tomato appeared during the fall-winter season, whereas the highest TSSs (4.8 oBrix) was observed in the fruit harvested during the spring-summer season. The Vietnamese cultivar ‘FM 120’ showed highest values of fruit per plant (33.8), total yield (3.6 kg), and vitamin c content (13.9 mg/100 g) for both cropping seasons. However, the highest values for the plant height, fruit length, fruit width, and fruit weight were observed in the Korean cultivars. Therefore, the fall-winter cropping season is recommended as the optimum season for enhancing the fruit yield and characteristics of Korean tomato cultivars under the environmental conditions of Hanoi in Vietnam.
