Abstract: Keeping in view the importance of selection of traits for higher yield, a systematic research trial was undertaken to study trait association pattern with regards to yield to facilitate selection of traits in different Sarpgandha germplasm through its qualitative and quantitative traits at AICRP (M&APs) farm, BAU, Ranchi. Research was laid out in RBD with 25 treatments replicated thrice. Experimental material consisted of 25 germplasm of Sarpgandha (BRS1 to BRS25) collected from different districts of Jharkhand. Different qualitative and quantitative parameters were measured as per NBPGR guidelines. The replicated data of all the 25 germplasm for quantitative traits was subjected to correlation matrix and path value analysis. Correlation matrix showed that plant height had highly significantly positive correlation with dry root yield/plant (0.594) and significantly positive correlation between root length and dry root yield/plant (0.414). Path analysis of different growth parameter affecting seed yield/plant indicated maximum direct positive impact by number of flowers/ inflorescence (0.658) and maximum direct negative impact by number of fruits/inflorescence (-0.486). In case of dry root yield/plant, maximum direct positive effect was shown by plant height (0.590) and maximum direct negative effect was by root diameter (-0.472). So plant height & root length may be selected as suitable traits for improving dry root yield/plant in Sarpgandha.
