The genotypic coefficient of variation and heritability values in twenty strains of opium
poppy were low for latex yield, morphine content and seed yield. These values were high
for capsule breadth and capsule number. The partitioning of genotypic association of latex
yield revealed maximum directcontribution from morphine percentage (negative), capsule
breadth and leaf number. Direct effects of sizeable negative magnitude were also recorded
for plant height, capsule number and seed yield. Aplant type with few capsules, which are
broad in middle, dwarf stature, large leaf (the four upper most leaves) is suggested for
increased latex yield.
Keywords: Genotypic correlation, genotypic variation, heritability, latex yield. morphine, opium poppy, path analysis.
