With the aim to identify among some released upland rice (Oryza Sativa L.) cultivars those best adapted to upland conditions, the genotype x environrnent interaction for gram yield was studied. Eight genotypes grown in 21 environments in the State of São Paulo, Brazil, were evaluated from 1974 to 1977 seasons. Both genotypes x environments interaction and the variation among the environments showcd to he highly significant (P < 0.01 and P< 0.001, respectively). No significant statistical difference between cultivar yicIds was detected (P < 0.05) and none of the cultivars displayed linear regression coefficient different from unit (P > 0.05). ne norílinear component (sd) was highly significant (P < 0.01 ) for IAC 25, 'Pratão Precoce' and 'Batatais'; and nonsignificant for IAC 4 7, IAC 1246, IAC 113 1, IAC 5544, and IAC 5032, which are the most stable cultivars, and their responso to crívisom-nental changes could be predicted. Among the eight cultivars and the ecological conditions tested, these genotypes were the most promising lines toward stabje grain production.
