This work aimed at estimating the genetic divergence among 85 accessions of elephant-grass using the Gower algorithm for the joint study of quantitative and qualitative traits. The experiment was conducted in the city of Campos dos Goytacazes, Rio de Janeiro state, Brazil, with of 85 elephant-grass genotypes. It was applied a randomized block experimental.. Read More»

Authors: D.A. Rossi, R.F. Daher, T.C. Barb�©, R.S.N. Lima, A.F. Costa, L.P. Ribeiro, P.E. Teodoro and L.L. Bhering
Elephant grass is a perennial tropical grass with great potential for energy generation from biomass. The objective of this study was to estimate the genetic diversity among elephant grass accessions based on morpho-agronomic and biomass quality traits and to identify promising genotypes for obtaining hybrids with high energet..

Genetically improved cultivars of elephant grass need to be adapted to different ecosystems with a faster growth speed and lower seasonality of biomass production over the year. This study aimed to use selection indices using mixed models (REML/BLUP) for selecting families and progenies within full-sib families of elephant gra.. Read More»

Selecting elephant grass families and progenies to produce bioenergy through mixed models (REML/BLUP)
Authors: E.V. Rodrigues, R.F. Daher, A. dos Santos, M. Vivas, J.C. Machado, G. do A. Gravina, Y.P. de Souza, A.K. Vidal, A. dos S. Rocha and R.S. Freitas
Brazil has great potential to produce bioenergy since it is located in a tropical region that receives high incidence of solar energy and presents favorable climatic conditions for such purpose. However, the use of bioenergy in the country is below its productivity potential. The aim of the current study was to select full-sib.. Read More»

RAPD and ISSR markers in the evaluation of genetic divergence among accessions of elephant grass
Authors: R.S.N de Lima, R.F. Daher, L.S.A. Gon�§alves, D.A. Rossi, A.T. do Amaral J�ºnior, M.G. Pereira and F.J.S. L�©do
Considering the expected genetic variability of elephant grass (Pennisetum purpureum), due to its cultivation in different continents, we characterized and estimated the genetic divergences between 46 accessions of elephant grass with different edaphoclimatic adaptations, using RAPD and ISSR markers. We evaluated, comparativel.. Read More»
