Effect of inbreeding in opium poppy (Papaver somniferum)

An experiment was conducted during 1991-92 to study the effect of inbreeding using 3 populations (selfed, open and sibbed) of 3 land races ('Early Red', 'Ghazipur', 'Kali Dandi'). Opium poppy (Papaver somniferum L.) is self pollinated crop with varied degree of out crossing. Differences due to varieties and mode of pollination were significant but no interaction was found between varieties and mode of pollination. 'Ghazipur' and 'Early Red' showed significant inbreeding on selfing for seed yield and opium yield while 'Kali Dandi' had no inbreeding for seed yield and very low non-significant for opium yield. The yield of sibbed population of each variety was at par to open pollinated population with higher magnitude in 'Kali Dandi'.
