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.
