Description: Genetic improvement programs ofperennialforage legumes in Brasil evaluate accessions in row plots without considering the genetic variability within accessions. Individual plant evaluations would not only allow for selection ofthe best accessions but also for the best individuais within accessions. This procedure is however more labor-intensive and expensive. The effectiveness ofusing the simulated individual BLUP selection method (BLUPIS) was assessed in a trial with Stylosanthes capitata and S. guianensis in a completely randomized block design with 35 accessions, six plants per plot and six andfive replications, respectively. The method can be applied when only total plot yields are measured and provide selection at the individual plant levei. Results showed a high correlation between selection by the traditional BLUP and the alterna tive BLUPlS methods. The latter is recommendedfor improving species in which individual plant evaluations are difficult.
