Correlation and path coefficient analysis for yield and yield contributing traits in double-cross f2 populations of tomato (Solanum lycopersicum L.)

Abstract:
Association studies in two double cross F2 populations revealed that plant height, number of clusters, number of fruits per plant and average fruit weight were positively associated with fruit yield per plant in both doublecross F2 populations. Plant height exhibited positive direct effect on fruit yield per plant in TSH-2 X TSH-6 F2 populations while negative direct effect was indicated in F2 populations of the cross TSH-2 X TSH-8. Fruits per plant recorded positive direct effect on fruit yield per plant in the F2 populations of both double cross hybrids. Average fruit weight exhibited positive direct effect on fruit yield per plant in all the F2 populations except F2 population of TSH-2 hybrid and TSH-2 X TSH-8 hybrid.
