Abstract: An experiment was conducted at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) experimental field to evaluate selected tomato (Lycopersicon esculentum Mill.) varieties for their seed yield under irrigated condition. The experiment was set using a Randomized Complete Block Design (RCBD) with three replications wherein nine tomato varieties: five determinate type (Bishola, Chali, Cochoro, Fetan and Melkasalsa) and four semi-determinate type (Metadel, Miya, Melkashola and Arp tomato d2) and one local variety (Roma VF) were used. Data was collected on yield, seed weight per fruit, seed weight per plant, seed yield per hectare, number of seed per fruit, thousand seed weight, fruit diameter, fruit weight per plant and fruit yield per hectare. The results revealed that Variety had highly significantly (p≤0.01) affected the yield and yield component parameters. Significantly the highest fruit diameter (6.25 cm) was recorded from variety Bishola whereas the lowest seed yield per hectare was obtained from Fetan (58.1 kg). Correlation analysis also indicated that Seed weight per plant was significantly and positively associated with seed weight per hectare (r = 0.95), fruit yield per hectare (r = 0.40) and fruit weight per plant (r = 0.40). Fruit weight per plant was highly significantly and positively correlated with seed weight per hectare (r = 0.47) and fruit yield per hectare (r = 0.99). The tomato variety Bishola was found to be high seed yielder as compared to the other varieties compared and hence it is suggested that tomato producers in Jimma area can use Bishola variety for high seed yield.
