RESUMEN. "INIA YRUPÉ" se recomienda para la producción de otoño, invierno y primavera bajo cultivo protegido. Posee un desempeño superior a 'INIA Ágata' en productividad semi precoz, arquitectura de planta, forma y sabor de fruta, con la ventaja de tener menor incidencia de botrytis, arañuelas y oidio.
Abstract: The domestication of plants, as a bio-cultural process, is a continuous phenomenon intrinsically associated with the use of plants. Traditional and scientific knowledge constitute the basis of the various uses of plants from in situ harvesting to complete domestication of crops. One of the most important challenges of our time is to achieve the conservation and sustainable use of plant genetic resources of landraces, species in the process of domestication and species used in situ.

Abstract. Acca sellowiana, known as 'Guayabo del País' or 'Pineapple guava', is a small evergreen ornamental fruit tree of the family Myrtaceae, native to Uruguay and south-eastern Brazil. It has excellent agronomical and commercial potential, high nutritional value, and is adequate for fresh consumption as well as for the elaboration of manufactured products. Several genotypes with outstanding fruit size and flavor have been selected in the breeding program for this species in Uruguay.
ABSTRACT. The manipulation of ploidy is a helpful tool in improving crops and grasses. Trifolium polymorphum (Poir.) (Leguminosae) is a native perennial stoloniferous winter species that combines different types of reproductive systems. This biological advantage makes T. polymorphum a remarkable issue of research. T. polymorphum belongs to the Campos region and has evolved into adapted ecotypes through long exposure to environmental stresses, grazing and by competing with the native C3 and C4 grasses which have dominated the Campos vegetation over a long period of time.
ABSTRACT. The genetic relationships among 34 accessions of wild rice from Asia, Africa, America and Australia were analysed using RFLP technique. After southern blotting, DNA digestion pattern was hybridised with a highly repetitive DNA sequence of a retrotransposon from a gypsy family of mobile elements. A dendrogram was constructed from RFLP data in which the species clustered according to their genome designation (CC, BB, BBCC and CCDD genomes). Some species did not appear in the same group, for example, O. eichingeri from Africa and Sri Lanka clustered separately from each other.
La marchitez bacteriana causada por Ralstonia solanacearum es la principal enfermedad bacteriana en cultivos de papa (Solanum tuberosum), no existiendo al presente variedades comerciales resistentes. El programa de mejoramiento de papa en INIA ha evaluado el gen efr de Arabidopsis thaliana para el desarrollo de genotipos resistentes a marchitez bacteriana.
