Nuevo cultivar de soja de la EEAOC: Yanasu RR.

Abstract

Durante las últimas décadas, el cultivo de la soja a nivel mundial tuvo un crecimiento tanto en superficie, como en productividad. En la Argentina sucedió de igual manera, particularmente a comienzos de este siglo, como resultante del uso de alta tecnología, convirtiendo a este cultivo y a sus subproductos en el pilar del sistema granario y exportador. El desarrollo del Noroeste Argentino (NOA) coincidió con el proceso a nivel nacional. La Estación Experimental Agroindustrial Obispo Colombres (EEAOC) de Tucumán buscó permanentemente producir cultivares adaptados a esta zona, siendo este el principal objetivo del subprograma Mejoramiento Genético del Proyecto Soja. Yanasu es una nueva variedad de soja liberada por la EEAOC, que completa su madurez fisiológica a los 123 días de su siembra (pertenece al grupo de madurez VIII corto) y que logra excelentes potenciales de rendimiento. Fue obtenida a través de cruzamiento y posterior avance generacional en la subestación de Monte Redondo (San Agustín, Tucumán). Yanasu RR fue sometida a ensayos comparativos de rendimiento (ECR) en cuatro diferentes sitios del área sojera tucumana durante la campañas 2005/2006 y 2006/2007, alcanzando rendimientos superiores a los testigos en la mayoría de los ensayos. Exhibe, entre otras características, baja o nula dehiscencia de vainas y un peso de 1000 semillas de 162,6 gramos. En cuanto a su sanidad, se destaca su tolerancia a las enfermedades cancro del tallo y mancha ojo de rana, así como ante patógenos de semillas como Cercospora kikuchii, Alternaria spp. y Macrophomina spp. Desde 2009/2010 se la incluyó en la Red de Evaluación de Variedades Comerciales del NOA, destacándose por encima del testigo en 12 localidades de la región, con un excelente potencial de rendimiento.

In recent decades, soybean planted area, production, and productivity have increased worldwide. This has also occurred in Argentina, especially during the last century, based on the use of high technology, which has turned this crop and its products into the cornerstone of grain and exportation systems. The development of this crop in North Western Argentina has coincided with the process at the national level. Estación Experimental Agroindustrial Obispo Colombres (EEAOC) from Tucumán is constantly producing new technology, partly through the generation of new varieties adapted to this area. Yanasu is a new soybean variety released by the EEAOC, with 123 days to physiological maturity (it belongs to early maturity group VIII) and excellent yield potential. It was obtained by parental crossing and subsequent generation advance at Monte Redondo sub-station, in San Agustín, Tucumán. Comparative yield trials were conducted at four different sites in the soybean area in Tucuman during the 2005/2006 and 2006/2007 seasons. Yanasu presented higher yields than the control in most trials. Among other characteristics, it showed very good resistance to shattering and lodging and a 1000 seed weight of 162.6 grams. As for its sanitary conditions, it exhibited an outstanding tolerance to stem canker disease and frog eye spot, as well as to seed pathogens such as Cercospora kikuchii, Alternaria spp. and Macrophomina spp. Since the 2009/2010 season, Yanasu has been included in the evaluation network of commercial varieties in North Western Argentina, and has proven to have an excellent yield potential, outdoing that of the control at over a dozen sites in the region.
