The present study was made on group of 22 strains of opium poppy to find out variability and suitable selection indices for opium and seed yield. Heritability in broad sense was high for capsula weigth/plant, plant height, capsule length, stem diameter, and opium yield. The distriminant functions is based on single character were less efficient while on the basis of combination it was in general more efficient. The comparison of different functions revealed that capsule weight/plant, capsule length, plant height are major yield component and thus particing selection for attainment of high opium and seed yield lines, maximum weight age could be given to these characters. The positive association of opium yield and seed yield suggested that by adopting suitable component breeding and selection, a dual-purpose varaity (opium and seed yield) may be developed.
