An article about Italian rice sent me scurrying once again to the International Rice Information System. That suggests, as you can see from the diagram at left if you click on it, that the rice variety Carnaroli is in fact the result of a cross between Vialone and Lencino. Vialone Nano is also mentioned in the article, along with Arborio. You — and no doubt Italian rice farmers — will be pleased to hear that all three varieties are safely conserved in the IRRI genebank.
