Performane of tomato genotypes in autumn season Khan Afzal, Jindal SK Department of vegetable Science, Punjab agricultural University, Ludhiana-141004, Punjab Online published on 12 July, 2017. Abstract The present study was carried out at Department of Vegetable Crops, Punjab Agricultural University, Ludhiana during 2010–2011. The experimental material consisted of 44 F1s of tomato (obtained through line × tester method by using 11 lines and 4 testers). Maximum phenotypic and genotypic coefficients of variability was observed for lycopene content followed by number of fruits per plant, total fruit yield, marketable yield, average fruit weight and plant height. The presence of narrow gap between phenotypic coefficient and genotypic coefficient of variability for all the characters under study, suggested that the traits studied have low environmental influence. Maximum genetic advance was observed for lycopene content followed by number of fruits per plant, total fruit yield, marketable yield, average fruit weight and plant height and therefore these characters can be improved with selection. Top Keywords Genotypic coefficients of variability, phenotypic coefficients of variability, Genetic advance, Selection. Top | |
