Genetic evidence for the conversion of the morphinan alkaloid thebaine to oripavine in interspecific hybrids between Papaver bracteatum and Papaver orientale
The alkaloid profiles of ripe capsules of Papaver bracteatum, P. orientale and their interspecific hybrids (F1 and BCF1) were determined and compared. In the hybrids the thebaine content declined, while that of o...

Genetic map** of an ancient translocation in the genus Lens
Segregation of 18 marker genes was monitored in selfed progeny of a Lens culinaris × L. ervoides hybrid; five linkage groups were mapped, one of which contained a reciprocal translocation break-point that differe...

Thebaine content and yield in induced tetraploid and triploid plants of Papaver bracteatum Lindl.
The effect of colchicine induced autotetraploidy on the thebaine content and yield of the capsules of Papaver bracteatum was studied. A significant increase in the thebaine content of the capsules was found in te...

Phylogenetic studies in Papaver section Oxytona: cytogenetics of the species and interspecific hybrids
Chromosome behaviour at meiosis was studied in the F1, F2, and backcross generations, in the three species of Papaver section Oxytona, and in artificially induced autopolyploids of P. bracteatum. Close homology w...

The genetics of hard seed coat in the genus Lens
Seeds of the cultivated lentil are capable of germinating shortly after maturation. The seed dormancy of wild lentil species is due to a hard seed coat. In crosses between the cultivated species L. culinaris and ...
