An experiment was conducted at the Institute of Agriculture and Animal Science (IAAS), Rampur, Chitwan, Nepal during the winter season of 2001-2002 to characterise and evaluate 10 exotic and local tomato landraces found in Chitwan district for their agro-botanical and economical characters under field condition. The results showed strong positive correlation between height and number of branches; and height and number of internodes per plant. Likewise, strong positive correlation was also found between reproductive and fruit characters such as number of clusters per plant and number of fruits per plant; and number of fruits per plant and yield per plant, where as a negative correlation was found between days to 50% flowering after sowing and days to 50% fruit set after flowering. The highest yield (3.36 kg/plant), and the highest average fruit weight (70 gm/fruit) were recorded in Tolstoi. On the other hand the highest plant height (160 cm) and the highest leaf length (45 cm) were recorded in Manisha and Tolstoi, respectively. Similarly, the highest main stem diameter (5 cm) was recorded in Tolstoi and Bramhapur 5. Punjab chhoda was the earliest blooming genotype (57 days after seeding), where as Pusa Earli Dwarf was the earliest fruit setting genotypes (10 days after flowering). The highest number of clusters (30) and the highest number of flowers per cluster (10) were recorded in Tolstoi and Manisha, but the highest number of fruits per cluster (1.66) was recorded in Manisha and CL 1131. Similarly, the highest fruit number/plant (50) was found in Manisha. Likewise, the highest number of internodes/plant (22) was recorded in Tolstoi. Fruit size varied from medium to large and fruit shape long, oval and round. In general, increment in fruit number per plant resulted an increment in yield per plant.
