פירוש על ברכות 73:9

A CONCLUSIVE REFUTATION OF RAV AND SHMUEL. The Gemara contradicted Rav and Shmuel who said that one does not recite בורא מיני מזונות on rice from a Braiso that clearly says one does recite בורא מיני מזונות when eating rice. The contradiction from the Braiso is exclusively about their opinion on rice, but about דוחן, millet, there is no contradiction. And it is possible that the halochoh is like them as far as millet is concerned and we do not recite on it, millet, בורא מיני מזונות.

And according to them the benediction for rice is: "...Who createst various kinds of foods."

Who maintained above that this benediction is restricted to the five species, excluding rice.
