The use of selected cultivars is one of the easiest technologies for adoption by the farmer; besides yield increase, it offers lower cost in the agricultural production. Thus, it is fundamental to obtain information about the performance of new cultivars, from the most diverse cropping regions. The purpose of this study was to evaluate the performance of the upland rice (Oryza sativa L.) (BRS Aroma, BRS Bonança, BRS Colosso, BRSMG Conai, BRSMG Curinga, BRS Soberana, BRS Talento and IAC 202) under rainfed condition in Cassilândia, MS, Brazil. A randomized complete block design, with four replications was used. The seeds were sowed on November 30 2006, with 0.40 m between rows and a density of 70 viable seeds per meter. The results showed that BRS Talento, IAC 202, and BRS Soberana presented better performance. BRS Soberana, BRS Bonança, BRS Colosso, IAC 202, and BRS Talento presented larger whole grain yield. It is possible to obtain good rice grain yield higher than 3,000 kg ha-1, under rainfed condition in Cassilândia, MS, since appropriate cultivars are used.
