The field trials were conducted at Agricultural Research Station, Bangladesh Agricultural Research Institute, Burirhat, Rangpur, Bangladesh during the cropping season of 2012-13. The location is situated in the subtropical climatic zone with wet summer and dry winter. The studies were conducted during the winter of 20012-2013. The study area is generally characterized by moderate weather conditions. During the culture period, the mean air temperatures were ranged from 15.8-28.5 °C and relative humidity ranged from 72.5-79.5%. Although relative humidity did not fluctuate during the growing period temperatures were increased after January i.e., the fruit development stage. A few rainy days were also evident during the fruit development and harvesting period was found in the experimental site. Ten tomato lines denoted as V1, V2, V3, V4, V5, V6, V7, V8, V9, and V10 were collected from SAARC countries were used as planting material along with BARI Tomato- 14 as check. Seeds of the tested lines and variety were sown in the seedbed on 15 November 2012. Thirty-two days old seedlings were transplanted in the main field on December 17, 2012. The experiment was laid out in a completely randomized block design with three replications. The unit plot size was 4.0 m x 1.0 m with maintaining the spacing of 60 cm x 40 cm. The crop was fertilized with 10 t, 550 kg, 450 kg, and 250 kg of cow dung, urea, triple Superphosphate, and muriate of potash per ha, respectively. Half of the quantity of cow dung, the entire amount of triple superphosphate, and half of the muriate potash were applied during land preparation. The remaining half of cow dung was applied during pit preparation. The rest of muriate of potash and the entire amount of urea was applied in three equal splits at 15, 30, and 45 days after transplanting. Irrigation, pruning, mulching, weeding, plant protection measures, and other intercultural operations were done as and when necessary. Tomato leaf curl virus and tomato mosaic virus was found on a few plants and these are controlled by spraying Dithane M45 and finally by uprooting. Insects were controlled by using Malathion 57 EC (2 times at 25 and 32 days after transplanting). Application of plant growth regulators such as GA3 was sprayed @ 20 ppm at 30 days after transplanting for better plant growth. Data were recorded on different parameters. Data were collected in this study were on plant types, days to 50% flowering (days from the date of sowing to flowering 50% plant), plant height (when the plants attained the maximum height after which the plant ceased to grow for measurement the plant were selected randomly), number of fruits per pant (fruits harvested from ten plants of each treatment were counted and converted number of fruits per plant), weight of fruits per plant, average fruit weight (measured with the help of balance and their average was taken), fruit length (when the fruit attained certain maturity then the length was measured with the help of measuring tape), fruit yield, days to 1st harvest, fruit length (when the fruit attained certain maturity then the length was measured with the help of measuring tape), fruit diameter (fruit diameter was measured with the help of vernier caliper, when the fruit reached up to certain maturity), number of locule per fruit (matured fruits were cut by a sharp knife and locules number were counted), thickness of pericarp (Thickness of pericarp was measured with the help of vernier caliper, when the fruit reached up to certain maturity), total soluble solids (It was measured with the help of refractometer), shelf life (marketable shape, size and colour containing fruits were collected from each treatment then they are kept in a room with room temperature and days were counted just before rotten), and virus infection was calculated by the following formula. Virus infection (%) = Number of virus-infected plants/Number of total plants x 100; Fruit yield per plant was tomatoes were got maturity and at harvesting stage per picking. The yield per hectare was calculated following the formula as Yield (Kg ha − 1) = Yield (kg per ha) x 100/Plot size (m2). Collected data were statistically analyzed using MSTAT-C computer package program and the mean was calculated. Means were separated following Duncan's Multiple Range Test at a 5% level of significance (Gomez and Gomez, 1983).
