What it is to have friends, especially knowledgeable friends. Bhuwon Sthapit, local rice wallah extraordinaire, ((I do hope that’s not a derogatory epithet. Let’s just say he knows more about rice than anyone I’ve ever met.)) responded quickly and in depth when asked what he knew about triple-grained rice.
Unique local rice landraces in Nepal are being lost, replaced by modern varieties. At least two of these are multi-seeded: Laila Majnu (the name refers to a pair of famous lovers, never separated until death) and Amaghauj (which means cluster of mango). Until 1999 Amaghauj was grown by one farmer on 3 katha of land, but was discontinued as the land was sold to another farmer. This local variety has a cluster of spikelets (at least 3 potential grains) originating from the same base; this heritable trait could potentially be used to breed new rice types offering increased yield. It is currently saved in community seed banks.
As Bhuwon also notes:
There is great potential to link community seed bank and national seed bank to harness such untapped and unknown resources.
And if you want even more, another friend, Ruaraidh Sackville Hamilton, Head of the IRRI genebank, points to Morphological Observations on Many Kerneled Grains in Rice. Don’t be scared by the Chinese; English follows.
LATER: For completeness, the name of the Bangladeshi variety which started all this, Biram Sundori, means “beautiful girl from Birampur,” which is the place where it is grown. Thanks to Zakir Sor for leading us all on this journey of discovery.
