ABSTRACT

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 10fruits 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.
