Path coefficient analysis in coriander (Coriandrum sativum L.) genotypes for fresh biomass yield under different seasons

An investigation was carried out at Department of Spices and Plantation Crops, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore during three seasons viz., season I (June 2008-August 2008), season II (October 2008-December 2008) and season III (June 2009-August 2009). From the results of the path coefficient analysis, plant height, number of branches, number of leaves, fresh weight of leaves, weight of stem and weight of root exerted the maximum positive direct effect on yield of biomass.
