Performance of tomato genotypes in the western undulating zone of India

Abstract

An experiment was conducted to evaluate the comparative performance of 10 tomato cultivars in the western undulating zone of Odisha during 2010–11 and 2011–12. The tallest plant was manifested by BT-106 (78.6 cm) followed by Utkal Pragyan (73.6 cm) and Swarna Lalima (69.5 cm) while shortest plant height (39.6 cm) was recorded in Utkal Urvashi. Maximum number of branches was found in BT-106 (10.8) followed by Utkal Pragyan (9.4) and minimum in Utkal Urvashi (5.7). The period required between transplanting and harvesting of first mature fruit varied between 73 to 90 days. The diameter of the fruit ranged between 3.3 cm in Utkal Pallavi to 4.9 cm in Utkal Raja. Similarly the length of fruit was highest in Utkal Urvashi (4.8 cm) and lowest in BT-106 (3.1 cm). Swarna Lalima produced the highest individual fruit weight (57.0 g) followed by Utkal Urvashi (50 g) and BT-10 (41.7 g) while lowest mean fruit weight was recorded in Utkal Dipti (23.3 g). The variety BT-106 recorded the highest fruit yield (2.2 kg/plant) followed by Utkal Pragyan (2.1 kg/plant) while minimum fruit yield of 1.5 kg/plant was notice in variety Utkal Urvashi (BT-12). Likewise the per hectare yield was highest in BT-106 (49.7 ton/ha) followed by Utkal Pragyan (45.8 ton/ha), Swarna Lalima (42 ton/ha) and Utkal Raja (40.4 ton/ha). Lowest fruit yield of 31.8 ton/ha was recorded in BT-12 ie Utkal Urvashi.
