“…Previous studies on the Papaver genus encountered problems distinguishing mainly P. somiferum apart from P. setigerum 20 . Based mainly on size, other authors 16 , 20 stated that the high variability within the species P. somniferum makes it impossible to distinguish between the different subspecies. Future research may include a higher number of varieties and accessions to better assess the intra(sub)specific variability in terms of cell number, size and shape, including in terms of environmental conditions 34 .…”

Opium poppy (Papaver somniferum L. subsp. somniferum) was likely domesticated in the Western Mediterranean, where its putative wild ancestor is indigenous, and then spread to central and northern Europe. While opium poppy seeds are regularly identified in archaeobotanical studies, the absence of morphological criteria to distinguish the seeds of wild and domestic forms prevents the documentation of their respective historical and geographical occurrences and of the process of opium domestication as a whole. To fill this gap and better understand the status of this crop in the Neolithic, we combined seed outline analyses, namely elliptic Fourier transforms, with other morphometric descriptors to describe and identify Papaver setigerum, Papaver somniferum and other Papaver taxa. The combination of all measured parameters gives the most precise predictions for the identification of all seven taxa. We finally provide a case study on a Neolithic assemblage from a pile-dwelling site in Switzerland (Zurich-Parkhaus Opéra, ca. 3170 BC). Our results indicate the presence of mixed populations of domestic and wild seeds belonging to the P. somniferum group, suggesting that the plant was already in the process of domestication at the end of 4th millennium BC. Altogether, these results pave the way to understand the geography and history of the poppy domestication and its spread into Europe.

“…Hrishi (1960) showed that P. setigerum (2n = 44) is one of the allotetraploids of P. somniferum (2n = 22) and Malik et al (1979) demonstrated that considerable homologies existed between somniferum and setigerum genomes and that somniferum or an allied form was involved in the origin of setigerum or both the species had a common parent in their origin. Hammer and Fritsch (1977), however, found diploid strains ofP. setigerum (2n = 22) "which can be considered as ancestral forms for the cultivated poppy also from the standpoint of chromosome morphology.…”

MORPHOLOGY AND ALKALOID CHEMISTRY OF PAPAVER SETIGERUM DC. (PAPAVERACEAE)

Summary Papaver setigerum DC. populations from Mediterranean France and Campania, southern Italy, have been studied morphologically and phytochemically. Papaver setigerum, whose circumscription is reported to be substantially the same as P. somniferum L., revealed to be a species morphologically distinct from the latter. Morphine, codeine, and thebaine, the major alkaloids of P. somniferum, are lacking in capsules of P. setigerum. Their absence supports also at the chemotaxonomical level that P. setigerum is a distinct species from P. somniferum.

“…Interspecific crosses are possible between the two species despite some meiotic abnormalities observed at the F1 generation (Malik et al ., 1979; Singh et al ., 1998). Notably, a diploid form of P. setigerum has been described (Hammer & Fritsch, 1977; Hammer, 1981). However, our data suggest that all the three accessions included in our study are tetraploids.…”

Opium poppy (Papaver somniferum) is one of the world's oldest medicinal plants and a versatile model system to study secondary metabolism. However, our knowledge of its genetic diversity is limited, restricting utilization of the available germplasm for research and crop improvement. We used genotyping-by-sequencing to investigate the level of genetic diversity and population structure in a collection of poppy germplasm consisting of 91 accessions originating in 30 countries of Europe, North Africa, America, and Asia. We identified five genetically distinct subpopulations. Although the accessions were from geographically diverse regions, no strong association was detected between geographic origin and subpopulation at regional and sub-regional levels. However, most accessions obtained from the same country were grouped together as genetically distinct, likely a consequence of the restriction on movement of poppy germplasm. Phylogenetic analysis identified clades that were largely consistent with the subpopulations detected. Clades could be differentiated broadly based on capsule dehiscence, plant stature and seed weight, traits believed to be associated with poppy domestication. Our study determined that the genetically diverse collection was likely composed of both wild and cultivated forms. This has direct implications for germplasm management and utilization of the available diversity for genetic improvement of poppy.
