To increase productivity, new types of beans that present different characteristics, such as higher grain yieldare necessary. The cultivar RS Centenário is the result of a selection carried out in 2007 using the “Iraí” cultivar, in a plot of genetic seed production. In the 2008 crop season, the seeds of the selected plants originated a segregant population. In 2009, the mass selection was carried out again. After two advancing generations, the phenotypic uniformity of the population was reached and the seeds were harvested in bulk. After several tests, the “SM 0112” lineage was denominated cultivar “RS Centenário” and the results of the assessed at a value for cultivation and use (VCU) trials were used to register the new cultivar. “RS Centenário” was registered as a new cultivar to be commercially grown in the Rio Grande do Sul state (RS), in southern Brazil. “RS Centenário” is a common bean (Phaseolus vulgaris L.) cultivar with a brindle seed coat, average weight of 1,000 seeds of 343 g, erect plants, indeterminate growth habit II/III, cycle of 88 days, high added value and average yield of 1,685 kg ha-1.
