Conteúdo: | A study was carried out to investigate the genotype x environment interaction and study the yield stability of storage roots in eight cassava cultivars, using methodologies by Plaisted and Peterson (1959), Lin and Binns (1988) and Kang (1988), in the counties of Maringá and Rolandia in 1996/97 and 1997/98. The treatments were set out in randomized complete blocks with four replications. The Branca de Santa Catarina, Fibra, IAC 41-85 and IAC 45-85 cultivars were the most stable according the Plaisted and Peterson (1959) methodology, while the Fibra cultivar, by the Lin and Binns methodology (1988), was oustanding with the lowest possible Pi value and greatest influence of the genetic deviation component. It was the more stable cultivar defined by this methodology. According to Kang (1998) methodology, the Fibra, IAC 45-85 and IAC 163-85 cultivars were the most stable and presented good yield.
