Correlation and path analysis for yield and quality traits in tomato (Solanum lycopersicum L.)

Abstract

Forty two genotypes of tomato including four check cultivar (GT-2, GT-6, JT-3, Pusa Ruby) were planted in Randomized Block Design, during rabi, 2018 and were assessed to study correlation and path analysis for yield and quality traits in tomato. Genotypic correlation coefficients were generally similar in nature and higher in magnitude than the corresponding phenotypic correlation coefficients. Fruit yield per plant had exhibited highly significant and positive association with fruit length and shelf life of fruits while significant and positive correlation showed by fruit girth and fruit borer damage. Plant height, no. of branches per plant and no. of locules per fruit showed negative and significant association with yield per plant. Path analysis revealed that highest positive direct effects on fruit yield per plant was exhibited by fruit length, no. of fruits per plant, shelf life of fruits and fruit borer damage.
