An investigation was carried out using 20 opium genotypes, to study character association between fourteen characters and their direct and indirect effect on seed yield and latex yield independently. Association study indicated that seed yield per plant had significant positive correlation with diameter of main capsule (0.60) and latex yield per plant (0.60). Whereas latex yield per plant had significant positive correlation with days to 50 per cent flowering (0.53) and seed yield per plant (0.60), indicating that seed yield and latex yield per plant can be improved by improving these correlated characters. Path coefficient analysis revealed that number of effective capsules per plant (73.04, 77.88) contributed most directly towards seed yield per plant and latex yield per plant, respectively. Whereas, other traits like stem diameter (59.55, 64.03), plant height (25.91, 27.80), peduncle length (29.35, 32.39), morphine content (21.33, 22.34) contributed both directly and indirectly to seed yield per plant and latex yield per plant, respectively. Therefore, this is suggested that the traits viz., no. of effective capsules per plant, stem diameter, peduncle length, plant height and morphine content may be considered as important traits during the selection for improvement of seed yield as well as latex yield per plant in opium.
