Character association and path study in tomato (Solanum lycopersicon)

Abstract

The present investigation, correlation and path in tomato was undertaken in randomized Block design with three replications on twenty genotypes at the Nana Ji Deshmukh Krishi Farm. The objective of the study was to evaluate correlation and path of traits among tomato accession based on quantitative traits. Thirty tomato acessession were planted in 2014-15 in randomized block design with three replications. Data on 15 quantitative traits were collected and subjected to various statistical analyses. As the study revealed, In general, genotypic correlations were higher than phenotypic ones in magnitude for all the characters. The character which showed negative association at genotypic level also showed negative association at phenotypic level. The fruit yield per plant exhibited significant and positive correlation with fruit diameter and fruit per plant at genotypic level while fruit yield per plant exhibited significant and positive correlation with fruit diameter and fruit per plant at phenotypic level. Path coefficient analysis revealed that the positive direct effect on fruit yield per plant was exhibited by fruit diameter and fruit per plant at genotypic level Path coefficient analysis revealed that the positive direct effect on fruit yield per plant exhibited by fruit diameter, fruit per plant, plant height, days to 50% flowering and fruits per cluster at phenotypic level.
