The rice crop Oryza sativa L., stands out as one of the most important crops of the San Martin region, both because of its extension and generation of economic dynamics. The purpose of the research was to obtain rice genotypes, through a multilocal trial, with acceptable agronomic and industrial characteristics, in order to counteract the scarcity of varieties that are currently cultivated and marketed in the San Martin region. A Randomized Complete Block Design (RCBD) was used, with a bifactorial arrangement. Factor A corresponds to ecosystems (three ecosystems); and Factor B, to rice lines and cultivars (varieties) (eight treatments), making a total of 24 treatments in combination, randomly distributed in three blocks, corresponding to a total of 72 experimental units; the evaluations were carried out using the Standard Evaluation System of rice of CIAT (International Center for Tropical Agriculture). The results obtained in the field were processed with the statistical program InfoStat, which showed that V5 (Cultivar introduced, Maja 6) had the highest yield, with an average of 7726.53 kg/ha, and at the level of genotype-environment interaction, the highest yield was obtained by V6 (El triunfo 960) in the Bajo Mayo with 8488 kg/ha. It was concluded that none of the local controls, La Esperanza and La Conquista, outperformed V6 in term of yield (introduced cultivar, El Triunfo 960) and V5 (introduced cultivar, Maja 6). In terms of phytosanitary aspects, V6 (introduced cultivar, El Triunfo 960) surpassed all the materials evaluated, showing maximum grades of 1, thus being considered resistant to most of the pathologies that attack rice cultivation. Finally, in terms of industrial performance, line V3 (LIP-2) showed the best pile yield, with 70.25%.
