Genetic variability, correlation and path coefficient studies in tomato

Evaluation of 20 genotypes of tomato elucidated high heritability with high GCV and genetic gain for-10 fruits weight, number of locules/fruit and fruit yield which could be improved by simple selection. The phenotypic and genotypic associations of fruit yield were significant and positive with 10-fruits weight, fruit girth, TSS (only at genotypic level) and number locules/fruit but significant and negative with plant height. Ten-fruit weight had significant and positive correlation with fruit length, fruit girth and number of locules/fruit at both levels. Path analysis confirmed that 10 fruits weight had highest positive direct effect followed by number of locules/fruit. Hence due weightage should be given to both characters while imposing selection for amelioration of fruit yield in tomato.
