Abstract: Keeping in view the importance of selection of traits for higher survival of Sarpagandha cuttings in nursery by using PGRs, a systematic research trial was undertaken to study trait association pattern and path analysis in stem cuttings of Sarpagandha at AICRP (M&APs) farm, BAU. Research was laid out in Factorial Completely Randomized Design with 13 treatments replicated thrice. Parameters studied were days for initiation of shoot emergence, days for completion of shoot emergence, rooting percentage, number of primary roots/cutting, number of secondary roots/cutting, length of primary roots, length of secondary roots, sprouting percentage, length of shoots, area of leaves, basal diameter of shoot, number of leaves/cutting, number of sprouts/cutting and survival percentage of cuttings. Correlation matrix among traits of stem cuttings of Sarpagandha indicated that survival percentage is highly significantly positively correlated with 11 traits and among them maximum value is shown by sprouting percentage (0.962). Path analysis of traits affecting survival percentage of Sarpagandha cuttings indicated that six traits had direct positive effect, out of which maximum direct positive effect was shown by number of primary roots/cutting (2.120) and maximum direct negative effect (-1.878) was shown by number of secondary roots/cutting.
