RAPD analysis of the genetic diversity among accessions of Fabaceous forages (Poincianella spp) from the Caatinga

R. F. M. Mendes, Neto, R. B. Araújo, Nascimento, M. P. S. B. C., and Lima, P. S. C., “RAPD analysis of the genetic diversity among accessions of Fabaceous forages (Poincianella spp) from the Caatinga”, vol. 13, pp. 5832-5839, 2014.

Among members of the Fabaceae family, native to the Brazilian Caatinga, the species Poincianella pyramidalis and P. bracteosa exhibit particular potential as forage for cattle, sheep and goats. With the aim of establishing genetic relationships within Poincianella, random amplified polymorphic DNA analysis was performed on eight accessions of P. pyramidalis and two accessions of P.

Microsatellite in Aeschynomene falcata (Leguminosae): diversity, cross-amplification, and chromosome localization

C. A. Polido, Mantello, C. C., Moraes, A. P., Souza, A. P., and Forni-Martins, E. R., “Microsatellite in Aeschynomene falcata (Leguminosae): diversity, cross-amplification, and chromosome localization”, vol. 13, pp. 10390-10397, 2014.

Aeschynomene falcata is an important forage species; however, because of low seed production, it is underutilized as forage species. Aeschynomene is a polyphyletic genus with a challenging taxonomic position. Two subgenera have been proposed, and it is suggested that Aeschynomene can be split in 2 genera. Thus, new markers, such as microsatellite sequences, are desirable for improving breeding programs for A. falcata.

Spittle protein profile of Mahanarva spectabilis (Hemiptera: Cercopidae) fed various elephant grass genotypes

A. M. Auad, Martins, M. F., Fonseca, I., Paula-Moraes, S. V., Kopp, M. M., and Cordeiro, M. C., “Spittle protein profile of Mahanarva spectabilis (Hemiptera: Cercopidae) fed various elephant grass genotypes”, vol. 11, pp. 3601-3606, 2012.

An understanding of the interaction between spittlebugs and forage grasses is essential for establishing factors that favor productive pastures. In the present study, we evaluated the protein profiles of the spittle of Mahanarva spectabilis (Distant, 1909) (Hemiptera: Cercopidae) fed various elephant grass genotypes. Each plant was infested with a single fifth-instar M. spectabilis. After 24 h, samples of the spittle produced by each nymph were collected and stored at -20°C, after which their protein profiles were analyzed.

Impact of forage clipping treatments on performance of winter wheat

S. A. Jadoon, Ullah, H., Mohammad, F., Khalil, I. H., Alam, M., Shahwar, D., Malik, M. F. A., and Jamal, Y., “Impact of forage clipping treatments on performance of winter wheat”, vol. 12, pp. 5283-5288, 2013.

Farmers in northern parts of Pakistan face severe shortage of green forage for their livestock during the harsh winter season. Winter wheat has the potential to be used as a dual-purpose crop for forage plus grain production in these areas. Ten elite winter wheat lines from Oklahoma State University were evaluated at Hazara Research Station Abbottabad under unclipped and clipped treatment level during 2005-06. The material was planted in a randomized complete block design with three replications, with a row length of four meters and a row to row space of 25 cm.

Stigma receptivity, mode of reproduction, and mating system in Mesosetum chaseae Luces (Poaceae), a native grass of the Brazilian Pantanal

L. A. C. Silva, Pagliarini, M. S., Santos, S. A., and Valle, C. B., “Stigma receptivity, mode of reproduction, and mating system in Mesosetum chaseae Luces (Poaceae), a native grass of the Brazilian Pantanal”, vol. 12, pp. 5038-5045, 2013.

Mesosetum chaseae Luces, known regionally as "grama-do-cerrado", is abundant in the Pantanal region in Brazil and contributes significantly to livestock and environmental conservation. This species is under basic studies at Embrapa Pantanal (Nhecolândia subregion, Pantanal, Corumbá, MS, Brazil). In this study, we present data about stigma receptivity, mode of reproduction, and mating system for 10 accessions collected in Nhecolândia subregion (Pantanal). Stigma receptivity was optimal, producing innumerous oxygen bubbles upon testing with hydrogen peroxidase.

High degree of genetic diversity among genotypes of the forage grass Brachiaria ruziziensis (Poaceae) detected with ISSR markers

A. L. S. Azevedo, Costa, P. P., Machado, M. A., de Paula, C. M. P., and Sobrinho, F. S., “High degree of genetic diversity among genotypes of the forage grass Brachiaria ruziziensis (Poaceae) detected with ISSR markers”, vol. 10, pp. 3530-3538, 2011.

The grasses of the genus Brachiaria account for 80% of the cultivated pastures in Brazil. Despite its importance for livestock production, little information is available for breeding purposes. Embrapa has a population of B. ruziziensis from different regions of Brazil, representing most of existing variability. This population was used to initiate an improvement program based on recurrent selection.
