Genetic Variability and Character Association Analysis for Quantitative and Qualitative Traits in Tomato (Solanum Lycopersicum L.) Hybrids Under Protected Environment

Abstract

The present study was carried out with ten tomato hybrids in polyhouse at experimental farm Department of Agriculture Guru Nanak college, Budhlada (Mansa) Punjab during Rabi 2020-21 to assess the genetic variability and character association analysis for Quantitative and qualitative traits in tomato (Solanum lycopersicum L.) hybrids for protected environment. The experiment was laid out in randomized block design with three replications. Data were recorded for fourteen Quantitative and qualitative characters. The experimental results revealed considerable differences among the genotypes for all the characters. Higher phenotypic and genotypic coefficients of variation (GCV, PCV) were observed for total number of fruits per plant, plant height, and total soluble solid. Moderate level of GCV and PCV was recorded for flowering days, number of locules per fruit, fruit yield per plant, number of fruit per cluster, number of flower per cluster, fruit diameter, number of cluster per plant, fruit length. High heritability together with high genetic advance as % of mean was observed in all the characters. Plant height, number of cluster per plant, pericarp thickness, total soluble solids, total number of fruit per plant, number of flower per cluster and number of fruits per cluster showed positive and significant connection with fruit yield /plant. Path coefficient analysis highest positive direct effects on fruit yield /plant was shown by total number of fruits per plant, plant height and number of locule per fruit, pericarp thickness, total soluble solid, fruit length could be reliable selection parameters for evolving high yielding genotypes
