Online published on 15 February, 2014. Abstract The study was conducted at Udaipur, Rajasthan, India during rabi, 2009–11. The aim of study was to evaluate the inter-relationship of trait and husk recovery using path analysis with 24 isabgol genotypes collected from four major isabgol growing states namely Gujarat (4), Madhya Pradesh (1), Rajasthan (17) and Haryana (2) of India. The path coefficient analysis based on husk recovery, as a dependent variable implicated that seed yield/plant had the highest positive direct effect on husk recovery. This trait was followed by spikes/plant, leaf width and swelling factor. Biological yield/plant and harvest index had negative direct effect on husk recovery. The overall results demonstrated that seed yield/plant and spikes/plant were the most contributing traits on isabgol husk recovery and direct selection based on these traits would be advantageous.
