Comparison of stability methods in elephant-grass genotypes for energy purposes. Repositório Alice
ROCHA, A. dos S.; DAHER, R. F.; GRAVINA, G. de A.; PEREIRA, A. V.; RODRIGUES, E. V.; VIANA, A. P.; SILVA, V. Q. R. da; AMARAL JUNIOR, A. T. do; NOVO, A. A. C.; OLIVEIRA, M. L. F.; OLIVEIRA, E. da S..
Elephant grass is a plant of tropical origin with high biomass-production potential that stands out today as an alternative energy source. The potential of its genotypes depends on the genotype × environment interaction. The objective of this study was to estimate the genotype × environment interaction and compare stability methods in elephant grass for biomass production in a biannual cutting regime. The experiment was conducted in a randomized block design with two replicates and evaluations of 73 elephant-grass genotypes in six cuts. The trait dry matter yield was utilized for the analysis of the genotype × environment interaction and the stability. The stability analysis methods employed were those of Yates and Cochran, Plaisted and Peterson, Wricke,...

Estimates of heterosis parameters in elephant grass (Pennisetum purpureum Schumach.) for bioenergy production. Repositório Alice
MENEZES, B. R. S.; DAHER, R. F.; GRAVINA, G. de A.; PEREIRA, A. V.; SOUSA, L. B.; RODRIGUES, E. V.; SILVA, V. B.; GOTTARDO, R. D.; SCHNEIDER, L. S. A.; NOVO, A. A. C..
With a high growth rate and a DM yield of up to 80 t ha-1 yr-1, elephant grass (Pennisetum purpureum Schumach.) has been utilized as an alternative source of energy. However, genotypes adapted to and productive in the different regions of Brazil need to be developed. Thus, the objectives of the present study were to estimate and evaluate heterotic effects in elephant-grass hybrids obtained in a partial diallel cross (5 × 5), with the aim of assisting the superior hybrids selection for bioenergy production. The experiment was conducted in Campos dos Goytacazes, Rio de Janeiro, Brazil. The following traits were evaluated: plant height (HGT), stem diameter (SD), leaf blade width (LBW), number of tillers per linear meter (NT), percentage of DM (%DM), and DM...

Prediction of genetic gains by selection indices using mixed models in elephant grass for energy purposes. Repositório Alice
SILVA, V. B.; DAHER, R. F.; ARAÚJO, M. S. B.; SOUZA, Y. P.; CASSARO, S.; MENEZES, B. R. S.; GRAVINA, L. M.; NOVO, A. A. C.; TARDIN, F. D.; AMARAL JÚNIOR, A. T..
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 grass (Pennisetum purpureum) for biomass production. One hundred and twenty full-sib progenies were assessed from 2014 to 2015 in a randomized block design with three replications. During this period, the traits dry matter production, the number of tillers, plant height, stem diameter, and neutral detergent fiber were assessed. Families 3 and 1were the best classified, being the most indicated for selection effect. Progenies 40, 45, 46,...
