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»

Prediction of genetic gains by selection indices using mixed models in elephant grass for energy purposes

Authors: V.B. Silva, R F. Daher, M.S.B. Araújo, Y.P. Souza, S. Cassaro, B.R.S. Menezes, L.M. Gravina, A.A.C. Novo, F.D. Tardin and A.T. Amaral Júnior

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»

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. Gonçalves, D.A. Rossi, A.T. do Amaral Júnior, M.G. Pereira and F.J.S. Lédo

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»
