The ability of seed quality tests to predict field performance of soybean seed lots with different incidences of infection by the causal agents of phomopsis seed decay (PD), was evaluated. Different seed infection levels were induced in one ‘Corsoy 79’ soybean seed lot by exposing naturally infected pods to 0, 3, 4, or 5 d at >95% relative humidity and 25 °C. Seeds were then removed from pods and dried. Seed quality wase valuated by germination tests on creped cellulose wadding (Kimpac), rolled towel, and sand and by cold, accelerated aging (A.Aging), tetrazolium (TZ), and conductivity tests. Field emergence of these seeds was evaluated at two locations and two 1991 planting dates in Iowa. Differences between laboratory germination test results for seeds with low (6.4 and 11.5%) infection levels were minor. At higher infection levels (18.2 and 32.4%), test differences were as large as 23%.P homopsis-diaporthine fection was located primarilyin the seed coat with lesser infection levels in cotyledons. Cotyledonary infection was not associated with variation in test results, but seed coat infection was, as evidenced by greater numbers of infected-abnormal seedlings in Kimpac and towel tests than in other tests. Field emergence declined with increasing PD seed infection at all sites and planting dates. Kimpac, towel, sand, A.Aging, and cold tests gave good estimates of field emergence at seed infection levels to 18.2%, but at 32.4% infection, Kimpac and towel tests underestimated field emergence. Tetrazolium and conductivity tests overestimated seed quality at low and high infection levels.

ABSTRACT. - Peach production is of great economic importance in the Southern Cone of South America, having gone through great technological changes since its introduction during the time of Spanish and Portuguese colonies. The evolution of this crop has been determined by edaphoclimatic peculiarities, as well as by the culture and econ-omy of each country. The aim of this work is to summarize in one document the current situation and the specific characteristics of peach growing in Uruguay, Brazil, and Argentina. Technology incorporation, in all its different aspects, has made it possible to increase yields, so production has remained at the same level despite the reduction of the planted area. Also, a process of upscaling and concentration has been taking place, even though peach production characteristics keep making it especially suited for small growers. Great efforts have been made through universities and research institutes to develop local knowledge useful for growers and with poten-tial of great impact not only for them, but at regional level as well. The importance of genetic material for the success of the production system is paramount and strategies of developing cultivars with adaptation to local conditions have been embraced by the region, thus having a growing offer of new cultivars generated by local breeding programs. The integrated production approach is being generally applied, and alternative production systems that minimize or don?t use synthetic agrochemicals at all are being developed in many production areas. The planting density has been increased and the training and pruning systems are evolving towards simpler ones and prone to mechanization. Challenges to improve sustainability are many, but the belief among research groups on the capability to continue generating and making available technology and solutions for a broader and better availability of Prunus fruits on the consumers? table is also high.

RESUMEN. - El duraznero es un cultivo de gran importancia económica y social dentro de los países del Cono Sur de Suda-mérica. La evolución de este frutal se ha visto condicionada tanto por las particularidades edafoclimáticas, como por las culturales y las económicas de cada país. Sintetizar en un solo documento la situación actual y losdistintos aspectos que caracterizan al cultivo de durazneros en Uruguay, Brasil y Argentina fue el objetivo en este trabajo. La incorporación de tecnología en todos los sentidos ha permitido una mejora en los rendimientos, por lo que la producción se ha mantenido a pesar de la reducción del área de plantación. Últimamente se ha dado un proceso de crecimiento en escala y concentración de la producción, aunque las características del cultivo lo siguen haciendo muy apto para el pequeño productor. Grandes esfuerzos de investigación canalizados a través de universidades e institutos especializados han permitido generar información local y regional de alto valor e impacto. La importancia del material genético para el éxito del sistema productivo es clave y la estrategia de generar cultivares con adaptación local ha sido tomada por la región, siendo creciente la disponibilidad de nuevos cultivares generados por los programas de mejoramiento locales. El enfoque de producción integrada ha tomado gran impulso y son cada vez más las alternativas productivas que se desarrollan buscando prescindir de los agroquímicos, principalmente en lo que respecta al control de plagas y enfermedades. La densidad de plantación se ha ido incrementando y los sistemas de conducción y poda están evolucionando hacia formas más simples y pasibles de ser mecanizadas. Numerosos son los desafíos que hay por delante, pero a su vez es grande la convicción, entre los equipos de investigación, de poder seguir aportando para una mayor y mejor disponibilidad de frutos de Prunus en las mesas de los consumidores.
