Summary
A quantitative assessment of out-crossing in opium poppy was attempted using two strains (UO 221 C and NBPGR 1) possessing non-waxy stigmas and five strains (UO 177-2, UO 285, D 5-B, D 14 and UO 185) possessing waxy stigmas. The degree of out-crossing, measured over four years, was 15.3 per cent in non-waxy types and 45.8 per cent in waxy types. The overall mean worked out to 33 per cent.
