Character association and their direct and indirect effects on bulb yield in onion (Allium cepa L.)

An experiment was conducted to evaluate 75 diverge genotypes of onion during rabi season for correlation and path analysis for bulb yield and its contributing characters. The genotypic correlation coefficient values were higher than the corresponding phenotypic correlation coefficients in almost all the trait pairs. Path coefficient analysis revealed that the characters viz., neck thickness of bulb and number of leaves per plant exhibited moderate and positive direct effect on bulb yield.
