Resumo: The aim of this study was to evaluate the use of pollinator seed mixture to obtain hybrid rice seeds. The study was performed at Embrapa Clima Temperado, in the harvests of 2015/2016 and 2016/2017. Seeds of hybrids H7 and BRS AH 703 CL and the pollinator, Puitá INTA-CL cultivar were used in the proportions of 0.00%, 0.75%, 1.50%, 3.00%, 6.00%, 12.00% and 24.00% in the first year and 0.00%, 0.75%, 1.50%, 3.00%, 6.00%, 12.00% and 24.00%, 50.00% and 100.00% for the second year. The experimental design was a randomized complete block design with four repetitions and the data was submitted to analysis of variance. Seeding was performed in November and October. The plots were 5 meters long with 4 meters of plot area, being evaluated: Number of plants.m-2, Number of culms.m-2, Number of panicles.m-2, Panicle length, Productivity of grain, plot uniformity, plant height, percentage of whole grains, broken grains. Plants from hybrid rice seeds in the mix had no effect on yield components. Plants from hybrid seeds showed plot uniformity like plants from self-fertilization. The industrial quality of the grains was like grains of self-fertilized plants but differing in the intermediate mixtures used.
