Correlation Coefficient and Path Analysis in Coriander (Coriandrum sativum L.) Genotypes

The field experiment was carried out during Rabi season of the year 2010-2011 at Main Experiment Station (Vegetable Research Farm), Narendra Deva University of Agriculture and Technology, (Narendra Nagar) Kumarganj, Faizabad (U.P.) India. 110 lines of coriander germplasm maintained in All India Co-ordinated research project on spices under Department of Vegetable Science NDUAT, Kumarganj, Faizabad were taken for this investigation. This study revealed that the seed yield per plot showed highly and positive significant correlation with test weight (0.6008) followed by seed yield per plant (0.5995). The highest positive direct effect on seed yield per plant (g) was exhibited by test weight (0.3225) followed by secondary branches per plant (0.2292) and umbellets per umbel (0.1087). The perusal of path coefficient analysis shown that the highest positive direct effect on seed yield per plant (g) was exhibited by test weight (0.3225) followed by secondary branches per plant (0.2292) and umbellets per umbel (0.1087). Therefore, greater emphasis should be given on these characters while selecting for higher yield and related traits.
