COTONOU, BENIN] Africa's indigenous rice varieties are to be granted 'elite' status by scientists in the hope that they will play a central role in making farmers' crops more resilient.
Elite rice varieties are recognised to be high-yielding and include Asian rice, which has sometimes been improved with individual traits taken from lower-yielding African rice. Now scientists have shown that African varieties are resilient and high-yielding in their own right.
According to Savitri Mohapatra, spokesperson for the Consultative Group on International Agricultural Research, scientists from the Africa Rice Center (AfricaRice), Benin, did a series of studies on the yield of African rice and the factors that determine high yield — the latest of which was conducted last year (2009).
They concluded that, contrary to common belief, the yield of African rice is not inferior to that of Asian rice under the unfavourable growth conditions that often prevail in parts of Africa.
"This is contrary to the conventional thinking of rice researchers — that African rice has low yield potential," Mohapatra said.
African rice — Oryza glaberrima — was first domesticated in West Africa more than 3,000 years ago. Now it is on the verge of extinction and most African farmers have turned to Asian rice (O. sativa).
