Morphological Characterization of Tomato (Solanum lycopersicum L.) Germplasm in Tarai Region of Uttarakhand

The present investigation was conducted during 2012 at Vegetable Research Centre, Pantnagar, U.S.Nagar, Uttarakhand. The field experiment was laid out in Randomized Block Design with 29 genotypes along with two checks in three replications. Genetic variability was studied for 17 quantitative characters. The results revealed significant differences among the genotypes for all the characters. High genotypic and phenotypic coefficient of variations were observed for number of fruit clusters per plant (49.84 and 51.16, respectively) and lowest for days to first fruit picking (1.51 and 1.41 respectively). Heritability was found low for days to first fruit picking (0.13%) and high for number of fruit clusters per plant (100%). High genetic advance was observed for 1000 seed weight (484.88) whereas lowest for fruit diameter (0.24). Genotypic correlation coefficient was higher than phenotypic correlation coefficient.
