Studies on genetic parameters for yield and yield attributing traits in tomato (Solanum lycopersicum L.)

Abstract

59 genotypes of tomato including three checks were subjected to study the extent of variability present in the experimental material for yield and yield attributing traits at V.R.C., G.B.P.U.A. & T., Pantnagar, Uttarakhand, India for two consecutive years i.e. 2014 and 2015. Analysis of variance revealed the presence of high variability for all the 14 characters studied. Evaluation of 59 genotypes of tomato elucidated high magnitude of PCV as well as GCV for number of fruits/plant followed by average fruit weight (g), fruit yield (q/ha) and ascorbic acid (mg/100 g). The heritability coupled with genetic advance as per cent of mean were high for ascorbic acid (mg/100 g), number of fruits/plant, average fruit weight (g), fruit yield (q/ha), number of locules/fruit, pericarp thickness (mm) and number of fruits/cluster which suggests that these characters could be improved by selection.
