Abstract.
Pear is one of the most important temperate fruit crops. Uruguay aims at producing pears of high quality to reach regional markets as well as those of the Northern Hemisphere. Nevertheless, local climate variability and soil conditions frequently pose sanitary challenges for pear production, mainly in the south of the country, where the major pear producing area is located. Some new rootstocks of the series Old Home × Farmingdale (OH×F, Pyrus communis L.) were introduced from the pear germplasm collection of the US Department of Agriculture, National Clonal Germplasm Repository - Corvallis (NCGR) to the country with the aim of evaluating new materials and trying to identify those better adapted to local soil and weather conditions. To reach a reasonable number of plants in the shortest possible time, in vitro multiplication system was selected. This work was carried out to develop a protocol of in vitro propagation of different rootstocks, in order to generate faster plantlet production with high quality. A group of five different rootstocks from the OH×F series was selected: OH×F 40, OH×F 69, OH×F 87, OH×F 217, OH×F 333, and a local material identified as 00LBPrSJ. All genotypes were cultured in the same culture medium, a modification of the MS mineral salts. OH×F 217 and OH×F 69 exhibited the lowest multiplication rate in the culture medium used and produced less than two shoots per explant compared with OH×F 40 that produced more than five. The local selection had an average performance with four shoots per explant. Rootstocks showed differences in percentage of rooting and the survival during the acclimation which suggests the potential development of genotype-specific protocols.

ABSTRACT. -In this study, the Strawberry Innovation System in Salto (SIS) is analyzed, characterizing its main actors, according to their role and level of involvement. Technological innovations in the sector took place through a process that integrated the information generated by public research with the traditional culture of the region's producers, giving rise to alternative technologies that allowed the sustainable intensification of production. The methodology used in the research was the case study, which belongs to the qualitative paradigm; data collection was based on the conduction of eight semi-structured interviews with qualified informants of different types. Based on the results, it can be pointed out that in Salto, Uruguay, there has been a sis working for decades, whose actors are: the National Institute of Agricultural Research (INIA by its Spanish acronym), the Agronomy College, the General Directorate of the Farm (DIGEGRA), a group of nurserymen, businesses selling supplies and services, the ?Salto Hortícola? producer organization, the producers themselves and technical advisers. The synergic functioning of the system is explained by the role of research, which produces knowledge; its interaction with the strawberry nurserymen (primary dialogue network) to validate technologies, and the exchange developed with the rest of the actors to address production problems. It was found that there is a broader dialogue network, in which producers exchange technological proposals, contributing to the sustainability of cultivation in the region.

Las innovaciones tecnológicas en el sector se dieron a través de un proceso que integró la información generada por la investigación pública con la cultura tradicional de los productores de la región, dando lugar a tecnologías alternativas que permitieron la intensificación sostenible de la producción. La meto-dología de investigación fue el estudio de caso, perteneciente al paradigma cualitativo; la recolección de datos se basó en la realización de ocho entrevistas semiestructuradas a informantes calificados de diferente tipo. Según los resultados, puede afirmarse que en Salto, Uruguay, existe un sistema de innovación cuyos actores de mayor importancia son: el Instituto Nacional de Investigación Agropecuaria (INIA), la Facultad de Agronomía, el grupo de viveristas, las empresas comercializadoras de insumos, los productores y los asesores técnicos privados. El funcionamiento sinérgico en el sistema está explicado por el rol de la investigación que genera conocimiento nacional, original, orientado a solucionar problemas limitantes y con mayor facilidad de adopción, su interacción con los viveristas de frutilla en una red primaria de diálogo donde se validan tecnologías, se incorpora conocimiento local e internacional a través de la promoción del intercambio con el resto de los actores para abordar los problemas productivos. Se comprobó que existe una red de diálogo más amplia, en la que los productores intercambian propuestas tecnológicas, contribuyendo a la sostenibilidad del cultivo en la región.

RESUMO. - No presente trabalho são caracterizados os atores e analisado o funcionamento do Sistema de Inovação de Frutilla en Salto (SIF). As inovações tecnológicas no setor ocorreram por meio de um processo que integrou as informações geradas pela pesquisa pública com a cultura tradicional dos produtores da região, dando origem a tecnologias alternativas que permitiram a intensificação sustentável da produção. A metodologia da pesquisa foi o estudo de caso, pertencente ao paradigma qualitativo; a coleta de dados baseou-se na realização de oito entrevistas semiestruturadas com informantes qualificados de diferentes tipos. De acordo com os resultados, pode-se afirmar que em Salto, Uruguai, existe um sistema de inovação cujos atores mais importantes são: o Instituto Nacional de Pesquisa Agropecuária (INIA), a Faculdade de Agronomia, o grupo de viveiros, as empre-sas comercializadoras de insumos, produtores e assessores técnicos privados. O funcionamento sinérgico do sistema explica-se pelo papel da investigação na geração de conhecimentos originais, nacionais, direccionados para a resolução de problemas limitantes e com maior facilidade de adopção, a sua interacção com os viveiros de morangos numa rede primária de diálogo onde são validadas tecnologias, o conhecimento local e internaci-onal é incorporado por meio da promoção do intercâmbio com o restante dos atores para tratar de problemas de produção. Constatou-se que existe uma rede de diálogo mais ampla, em que os produtores trocam propostas tecnológicas, contribuindo para a sustentabilidade da cultura da região.
