A set of multiplex panels of microsatellite markers for rapid molecular characterization of rice accessions. Repositório Alice
PESSOA-FILHO, M.; BELÓ, A.; ALCOCHETE, A. A. N.; RANGEL, P. H. N.; FERREIRA, M. E..
This study aimed to analyze the efficiency of three new microsatellite multiplex panels, which were designed to evaluate a total of 16 loci of the rice genome, based on single PCR reactions of each panel. A sample of 548 accessions of traditional upland rice landraces collected in Brazil in the last 25 years was genotyped, a database of allelic frequencies was established, estimates of genetic parameters were performed and analysis of genetic structure of the collection was developed.

Extracting samples of high diversity from thematic collections of large gene banks using a genetic-distance based approach. Repositório Alice
PESSOA-FILHO, M.; RANGEL, P. H. N.; FERREIRA, M. E..
Background Breeding programs are usually reluctant to evaluate and use germplasm accessions other than the elite materials belonging to their advanced populations. The concept of core collections has been proposed to facilitate the access of potential users to samples of small sizes, representative of the genetic variability contained within the gene pool of a specific crop. The eventual large size of a core collection perpetuates the problem it was originally proposed to solve. The present study suggests that, in addition to the classic core collection concept, thematic core collections should be also developed for a specific crop, composed of a limited number of accessions, with a manageable size. Results The thematic core collection obtained meets the...

Genomic selection in tropical forage grasses: current status and future applications. Repositório Alice
SIMEÃO, R. M.; RESENDE, M. D. V. de; ALVES, R. S.; PESSOA-FILHO, M.; AZEVEDO, A. L. S.; JONES, C. S.; PEREIRA, J. F.; MACHADO, J. C..
The world population is expected to be larger and wealthier over the next few decades and will require more animal products, such as milk and beef. Tropical regions have great potential to meet this growing global demand, where pasturelands play a major role in supporting increased animal production. Better forage is required in consonance with improved sustainability as the planted area should not increase and larger areas cultivated with one or a few forage species should be avoided. Although, conventional tropical forage breeding has successfully released well-adapted and high-yielding cultivars over the last few decades, genetic gains from these programs have been low in view of the growing food demand worldwide. To guarantee their future impact on...
