El potencial de rendimiento simulado con el modelo Oryza V3, es en promedio de 15672 Kg Arroz/ha o 305 bolsas. La brecha de rendimiento explotable promedio (Yg-E) sería de 4562 kg de Arroz/ha (91 bolsas) para el promedio de Uruguay en relación a los rendimientos actuales de las últimas cuatro zafras. Esta brecha sería un 12.8% mayor (11 bolsas de arroz aprox.) en la región Este comparado con la región Norte-Centro. Los resultados presentados en este articulo de avance de investigación deben considerarse como preliminares ya que al realizar la validación en base a rendimientos actuales, mejorar la calibración de las variedades locales en las próximas etapas de este trabajo es probable que los valores de potencial estimado sean diferentes. En próximos trabajos se presentarán los resultados definitivos con una estimación de brecha de rendimiento más detallada para las distintas regiones del país. |

ABSTRACT.
Both linked and un-linked co-transformation can be used to overcome limitations of methods, such as re-transformation or sexual crossing of transgenic plants, to enable transfer of multiple genes to a single plant. Un-linked co-transformation can also facilitate the production of selectable marker-free transgenic plants. In this study, transgenic white clover plants were generated by Agrobacterium-mediated linked co-transformation using a single T-DNA of 9803 bp expressing: an isopentenyl transferase (IPT) gene for delayed leaf senescence under the control of an organ specific MYB32 promoter from Arabidopsis, a white clover nodule enhanced malate dehydrogenase (neMDH) gene for aluminium tolerance controlled by the endogenous Phosphate Transporter 1 (PT1) promoter, and the coat protein gene from Alfalfa Mosaic Virus (CP-AMV) controlled by the 35S promoter from Cauliflower Mosaic Virus. The selectable marker gene encoding hygromycin phosphotransferase (hph) was borne on a separate T-DNA. Forty independent transgenic events carrying the triple stack were generated, with estimated co-transformation efficiencies of 0.22 to 0.23%. Forty three percent of the events generated had a single insertion, while two events were selectable marker-free. Transcript abundance studies of the three transgenes of interest demonstrated the transcriptional competence of the inserted T-DNA. This study illustrates the feasibility of transferring multiple genes in a large single T-DNA into white clover by Agrobacterium-mediated co-transformation. Furthermore, observations of consistently delayed leaf senescence, statistically significant increases in TrneMDH transcript, and presence of CP-AMV transcript, support further analysis of these events for delayed leaf senescence under drought conditions, aluminium tolerance, and resistance to AMV.
