The objectives of this work were to evaluate the self-pollination as a tool in the elephantgrass (Pennisetum purpureum) breeding and to compare progenies of Pennisetum purpureum origined from different breeding strategies: self-pollination, intraspecific crossbreeds, and interspecific crossbreeds with Pennisetum glaucum. The experimental treatments were represented by the three fecundation forms: intraspecific crossbreed, interspecific crossbreed and self-pollination. A total of ten families originated from intraspecific crossbreed resulting in 160 progenies; two families originated from interspecific crossbreed resulting in 38 progenies, and […]

The experiment was carried out to evaluate factors related to the grazing efficiency of five Pennisetum sp. genotypes (CE 08 A.D., Venezuela, HV-241, Elephant B and Hexaplóide) during the dry period in the Forest Zone of Pernambuco. Genotypes were managed under rotational stocking (44 days of resting and four days of grazing period). It was used a split-plot arrangement in a complete randomized block design (genotypes represented the plots; grazing cycles, the subplots). Six replications were used to determine pre-grazing […]
