Identification of Tomato Genotypes for Growth, Yield and Quality Attributes under Eastern Dry Zone of Karnataka, India

Abstract

The experiment was conducted to study the 200 tomato genotypes for growth, yield and quality attributes. Among the 200 genotypes, the genotype Akshaya was exhibited least days taken to fifty percent flowering (21.00). In case of growth parameters maximum plant height noticed in genotype (13P3) 202.33 cm and maximum branches was observed in genotype (AR-56) i.e. 11.33 branches per plant. The highest fruit width and average fruit weight reported in (H-86) 8.15cm and (131.94 g). Yield attributing characters like number of fruits per plant (204.37) was highest recorded in EC-338717. The total tomato fruit yield highest was recorded per plant 6.48 kg genotype (4P1). With respect to quality parameters like Pericarp thickness highest was observed in (AOTD-10) i.e. 7.42 mm. The genotype AR-56 (7.00) was recorded highest total soluble solids. High range of fruit firmness was observed in (AOTD-18) 6.25 kg/cm2.  This study gives information on the agronomic variation in the 200 tomato genotypes assessed which can invariably serve as an index to selecting putative parents in breeding for new tomato variety that will combine desirable agronomic characteristics with high yield and its attributing characters.
