Elephantgrass (Pennisetum purpureum Schum.), also known as napiergrass, is a warm-season peren¬nial grass, which is used as forage in tropical and subtropical regions of the world. Elephantgrass produces large amounts of lignocellulosic biomass which makes it a promising bioenergy feedstock. Biomass yield and low input characteristics are the main targets for genetic improvement of elephantgrass. Breeding programs recombine desirable genetic variability from different accessions into new breeding lines for the development of advanced cultivars. This study aimed to characterize the genetic variability in selected accessions of elephantgrass using microsatellites markers. Genetic analysis was done for accessions PP 19, N 39-2, N 74, N 122, N 157 and N 190. Genomic DNA samples were amplified by PCR using previously developed primers to detect microsatellites molecular markers. The markers of each accession were converted into a numeric matrix, from which the genetic distances between the accessions were estimated. Agronomic traits from initial development and biomass production were also used to estimate genetic distances between each pair of accessions. Clustering analysis based on genetic distances allowed to detect a wide range of genetic variability among the evaluated accessions of elephant grass. The N 122 accession presented the highest genetic distance to the other accessions, while the genetic distance between N 157 and N 190 was the lowest using both molecular markers and agronomic traits. Genetic distances using molecular markers and agronomic traits had a significant positive correlation of 0.534. Microsatellites markers were also useful to confirm crosses between the accessions. The verified genetic variability indicates good potential for elephantgrass improvement by traditional breeding using these accessions.
