Abstract:
The aim of this work was to study the genetic diversity of elephantgrass ecotypes and recommend crosses for bioenergy production. The accessions of the Active Elephantgrass Germplasm Bank of Embrapa (BAGCE) classified in the standard ecotypes Cameroon and Napier were evaluated. Three evaluation cuttings were carried out. The 1st and 2nd cuttings were harvested at 250 days, and the 3rd, at 315 days. The genetic values were predicted by mixed model methodology via REML/BLUP. The Tocher clustering method was used to infer about the genetic diversity within the Cameroon and Napier ecotypes, based on the genetic dissimilarity matrix, obtained by the standardized Euclidean distance. The crosses recommendation was based on Tocher method using the matrix of genetic similarity. To the best of our knowledge this is the first study that investigate the genetic diversity of elephangrass ecotypes, aiming to select genitors and crosses to breed elephantgrass for bioenergy production. Our results indicate that elephantgrass accessions have high genetic diversity distributed in different clusters within each ecotype and crosses between Cameroon ecotypes are recommended to improve the elephantgrass for bioenergy purposes.
