Variation of major fatty acids in F8 generation of opium poppy (Papaver somniferum × Papaversetigerum) genotypes

The fatty acid compositions in F8 genotypes of a cross between Papaver somniferum×Papaver setigerum were studied. The oil content in both species was quite variable, ie 38·0% in P setigerum and 47·8% in P somniferum, while C18 fatty acids were quite comparable. The F8 genotypes had higher oil contents (>40%) and fatty acid concentrations than the parental species. Linoleic acid ranged between 68% (BRO 54) and 74·4% (BRO 59) and oleic acid varied between 13·6% (BRO 65) and 20·3% (BRO 54). High oleic desaturation ratio (ODR, >0·79) and C18 polyunsaturated fatty acid (>87%) with very low C18: 3 (0·37±0·01) indicate the possibility of using poppy oil for the edible oil industry. Oleic (18:1) acid was not correlated with the other fatty acids, except for significant negative correlation with linoleic (C18: 2) acid.

Alkaloid Spectrum of Opium of a Cross Between Papaver somniferum and P. setigerum

AbstractThe F8 generation of a cross between Papaver somniferum and P. setigerum shows considerable diversity in major alkaloids, the most important of which is morphine. The range of this alkaloid exceeds that of the superior parent, P. somniferum. Therefore, selecting superior individuals and poly crossing may enhance morphine content.
