The aim of this study was to produce original seed of two new rice cultivars obtained in Cuba, based on the selection of resistance to insect Tagosodes orizicolus Muir (Sogata). The study was developed at the Scientific Technological Base Unit (UCTB) “Los Palacios”, Cuba”, during 2013 and 2014. To that end, original and basic seed categories was were obtained, beginning with the evaluation of resistance to T. orizicolus Muir, agronomic characters and simultaneous selection with independent criteria; also the typical characteristics from each cultivar were considered. Thirty seven resistant lines to Tagosodes were identified and twenty of them kept a uniform behavior for agronomic characters, conformed the original seed of each cultivar. Basic seed from cultivars Anays LP-14 and Roana LP-15 were obtained to give them to the tate production system and for the subsequent extensive use in national production.
