Abstract
The present Experiment entitled “Studies on correlation and path coefficient analysis in Faba bean (Vicia faba L.)” was carried out at Genetics and Plant Breeding Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya. The experimental material constituted thirtynine germplasm lines including four check varieties viz., HFB-1, Vikrant, Rebya-40 and Giza-4. The experiment was carried out in Augmented Block Design with five blocks. The results of path coefficient analysis using simple correlation coefficient revealed that the highest positive direct contribution towards seed yield per plant was exhibited by harvest index (0.836) followed by plant height (0.708) and biological yield per plant (0.471). The days to maturity (-0.578), pod per plant (-0.502), pod fertility percent (-0.188), days to maturity (-0.086) and seed perpod (-0.024) were the characters having substantial negative direct effect on seed yield per plant. The traits indicated above as crucial direct and indirect yield components merit due consideration in formulating selection strategy in faba bean for selection of high yielding varieties.
