ESCOBAR, Marcela et al. Tarpusqa RR, novel soybean variety, released by EEAOC. Rev. ind. agric. Tucumán [online]. 2021, vol.98, n.2, pp.9-14. ISSN 1851-3018.

In the last decades, planted area, production, and productivity of soybean have increased worldwide. This has also occurred in Argentina, especially during the last century and based on the use of high technology, which has becomedthis 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. Tarpusqa RR is a new soybean variety released by the EEAOC, with 117 days to physiological maturity (it belongs to early maturity group VII) 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 three different sites in the soybean area of Tucuman during the 2008/2009 and 2009/2010 seasons. Tarpusqa RR 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 153 grams. As for its sanitary conditions, it exhibited resistance to stem canker disease and frog eye spot, as well as to seed pathogens such as Cercospora kikuchii and Fusarium spp.
