Assessment of Performance on Yield and Yield Contributing Attributes of Summer Tomato Genotypes in Bangladesh

Twenty three tomato genotypes were evaluated during summer season of 2011 to characterize and evaluate the yield performance under high temperature conditions. Days to first flowering ranged from 41.00 to 51.33 days among the studied genotypes. The highest number of fruits per plant (45.27) was recorded from the genotype FP5 × WP10 followed by C41 ×TLB182 (30.90) while it was the lowest (2.27) for the genotype TLB182. The genotype C41 × VRT004 had the highest fruit weight (80.81 g) closely followed by C51 × VRT004 (79.75 g). The genotype FP5 × WP10 yielded the highest amount of fruits per plant (1.90 kg) followed by C71 × VRT004 (1.61 kg). The corresponding yield (t/ha) was also the highest (64.6 t/ha) for FP5 ×WP10 followed by C71 ×VRT004 (54.74 t/ha).
