| Summary: | The present work aim was to obtain new rice cultivars resistant to Piriculariosis, as well as to produce their original seed based on the selection for their insect Tagosodesorizicolus Muir (Sogata) resistance. The work was developed in the UnidadCientíficoTecnológica de Base «Los Palacios», for this, the obtained lines were subjected to successive selections where the behavior against the fungus PyriculariagriseaSacc. in leaf and panicle neck, agronomic characters, and the behavior in front of Tagosodesorizicolus Muir (Sogata) populations were evaluated, as well as the simultaneous selection on all the characters evaluated, with independent criteria. The results obtained showed two new cultivars: `INCA LP-22' and `INCA LP-23', coming from crosses `Amistad'82' / `2077' and `INCA LP-1' / `Tetep' resistant to all the diversity of haplotypes of P. grisea present in the Caribbean location, in addition to excellent agronomic behavior, and the Tagosodes insect resistant, those that were included in the biodiversity fairs and its basic seed is in obtaining process, to facilitate the diffusion to the producers and in this way contribute to the improvement of crop diversity. |
