Description The capsule husks of a set of 115 Indian land races of opium poppy Papaver somniferum L. obtained over two
cropping seasons were screened for the percent contents of papaverine, reticuline, narcotine, thebaine, codeinone,
codeine, morphine and oripavine. Among the accessions screened 36, 7 and 1 did not accumulate papaverine,
papaverine and narcotine and codeine and morphine, respectively. The alkaloid profiles and correlations between
alkaloids in all the four classes of accessions showed that in the Indian genetic resources of P. somniferum (a)
morphine is synthesized from codeine rather than oripavine, (b) net alkaloid contents are low under narcotine
deficiency, and (c) accumulation of morphine and codeine was limited upstream of codeinone and morphinone.
The accessions identified to be harboring genetic blocks in the phenenthrine and benzylisoquinoline biosynthetic
pathways will be useful for understanding the genetic control of secondary metabolism in opium poppy.

support of the Department of Biotechnology Government of India for genebank work is gratefully acknowledged.
