Abstract: Keeping the importance of traits having significant impact of survival percentage of cuttings grown through vegetative propagation and their respective direct and indirect effect on it, a systematic research trial was conducted to know the trait association and path value analysis of independent characters on survival percentage of Gudmar cuttings under the influence of different concentrations of PGRs at AICRP (M&APs) farm, BAU, Ranchi. Research was laid out in Factorial Completely Randomized Design with 13 PGRs treatments replicated thrice. Survival percentage of cutting after 75 days of transplantation in polytubes is highly positively significantly correlated with 8 traits namely: Rooting percentage, number of primary roots, number of secondary roots, length of secondary roots, sprouting percentage, length of shoots, number of leaves per cuttings, number of sprouts per cutting and significantly correlated with days for completion of shoot emergence and area of leaves. Nine traits having direct positive effect are days for initiation of shoot emergence, days for completion of shoot emergence, rooting percentage, number of primary roots per cutting, number of secondary roots per cutting, length of primary roots, length of shoots, area of leaves, number of leaves per cuttings while four traits having direct negative effect are length of secondary roots, sprouting percentage, basal diameter of shoots, number of sprouts per cutting. Maximum positive direct effect was calculated for number of leaves per cutting (0.810) and minimum positive direct effect (0.060) was calculated for days for completion of shoot emergence followed by maximum direct negative effect (-0.087) calculated for number of sprouts per cutting and minimum direct negative effect (-0.942) was calculated for length of secondary roots.
