Study on genetic variability of different tomato (Solanum lycopersicum) cultivars grown under open field condition

Abstract

The present investigation was carried out at the Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya (BCKV) during 2017-18 period. The 53 genotypes were grown in RBD with 3 replications, in each replication there were 20 plants. Very high variance (Mean sum of squares for genotype) was recorded for some characters viz., fruit weight (1259.37), fruit number per plant (1124.65), plant height (551.28) and flower cluster per plant (192.55) indicated very wide range for these characters concerned. This investigation provides that high range of heritability occurs in plant height, primary branches/ plant, fruits per plant, flower cluster per plant, fruit weight, polar diameter of fruit, equatorial diameter of fruit, pericarp thickness, ascorbic acid content and s carotene content of fruit. Thereby, suggesting that study on the genetic diversity of the wide range of genotypes for the selection of promising parental lines.
