The objective this research is to determine the relation between the levels of genetic contamination (Female), density of sowing and hybrid types of irrigated rice to productivity. The experiment was carried out at an experiment camp of the Rice Tec Company, in the city of Glorinha (RS/BRAZIL), in the agricultural year of 2009/2010. The variables were four genetic contaminations (0%, 10%, 20% and 30%) three seed rate (35, 45 and 55 kilograms/hectare) and two hybrids (Avaxi CL and Inov), while the variable of result was yield. For the Avaxi CL there was no difference concerning productivity when the genetic contamination was increased. On the Other hand, the Inov hybrid showed the important yield difference in when the genetic contamination was increased and with different sowing densities.
