New varieties for the traditional upland and mechanized system Rice Nutrivars to Improve Nutrition and Health in Bolivia Therefore, Saavedra 27 can contribute not only to improve food security but also to improve nutrition and health in Bolivia ( Martinez, 2009 ) leading the way to a more eco-efficient rice production. A private-public alliance was set up between CIAT-Santa Cruz (state funded institution), ASPAR (Rice Growers Association), and CIAT-AgroSalud to evaluate high iron and zinc rice materials in Bolivia. Breeding lines from CIAT- AgroSalud were introduced and evaluated in farmer’s field from 2004 to 2008. ASPAR facilitated the evaluation of materials under irrigated conditions whilst CIAT-Santa Cruz tested materials under upland conditions by small-poor farmers with funding from PASA (Programa de Apoyo a la Seguridad Alimentaria del Ministerio de Agricultura de Bolivia supported by the European Union). Rice produced by small farmers is mainly for its own consumption ( Photo 1 ). Two rice cultivars, Azucena and CT16659-8-2CT-1-3-5-1, were identified as superior to local varieties and released by the Ministry of Agriculture in February, 2009 during a field day (Photos 2 and 3). Azuzena is recommended for planting under traditional upland conditions by small- resource poor farmers in Guarayos and Beni . Saavedra 27 is suited for irrigated-favored upland conditions in Saavedra, San Juan, Okinawa, San Pedro and Beni. Saavedra 27 was selected out of a cross between Perla X O.rufipogon and is the first variety released in Latin America from an interspecific cross.

[email_address] Introduction Rice is a key staple food for urban and rural consumers (36 kg/capita /year) in Bolivia, where it is grown by small-resource poor and medium size farmers using diverse production systems. Malnutrition is very high in Bolivia, and rice contributes with 10 and 8 % of the calories and proteins, respectively, to the Bolivian diet (FAO). Paititi and Tari, popular rice varieties grown by small-poor farmers in Bolivia, supplies around 154 and 167 ug of iron and 538 to 599 ug of zinc, respectively, to the Bolivian diet compared to 18 and 28 % more iron and zinc supplied by Saavedra 27, a new nutrivar released this year in Bolivia ( Pachon, 2009 ).

Strategic Alliances : Key to Success Saavedra 27 showed higher yield potential, good adaptation, tolerance to main diseases and insect pests compared to Epagri 108 (Table 1).
