SCOTTI, Carlos Alberto and NAZARENO, Nilceu Ricetti Xavier de. IPR 82-Araucária, potato cultivar for sustainable vegetable production. Hortic. Bras. [online]. 1999, vol.17, n.3, pp. 254-256. ISSN 0102-0536. http://dx.doi.org/10.1590/S0102-05361999000300017.
The main agronomic, industrial, and morphological characteristics of a new Brazilian potato cultivar released by IAPAR, Embrapa Hortaliças, Brasília-DF and Embrapa Sementes Básicas, Canoinhas-SC are presented. "IPR 82-Araucária" has been selected from clonal populations derived from crosses done in CIP, Lima, Peru, and introduced for field evaluations in 1984. High yield and field resistance to late blight have been the main features of the new cultivar, allowing to predict reductions as much as 50% in fungicides applications. Susceptibility to internal brown necrosis and common scab requires special farmer's attention in respect of planting density, liming, and irrigation management to decrease risks of incidence of these diseases. "IPR 82-Araucária" is potentially suited for organic farming, and for growing in areas close to water resources.
