| A wide array of molecular markers has been used to investigate the genetic diversity among common bean species. However, the best combination of markers for studying such diversity among common bean cultivars has yet to be determined. Few reports have examined the genetic diversity of the carioca bean, commercially one of the most important common beans in Brazil. In this study, we examined the usefulness of two molecular marker systems (simple sequence repeats - SSRs and amplified fragment length polymorphisms - AFLPs) for assessing the genetic diversity of carioca beans. The amount of information provided by Roger's modified genetic distance was used to analyze SSR data and Jaccards similarity coefficient was used for AFLP data. Seventy SSRs were... |

| Because of the continuous introduction of germplasm from abroad, some collections have a high number of accessions, making it difficult to explore the genetic variability present in a germplasm bank for conservation and breeding purposes. Therefore, the aim of this study was to quantify and analyze the structure of genetic variability among 500 common bean accessions to construct a core collection. A total of 58 SSRs were used for this purpose. The polymorphism information content (PIC) in the 180 common bean accessions selected to compose the core collection ranged from 0.17 to 0.86, and the discriminatory power (DP) ranged from 0.21 to 0.90. The 500 accessions were clustered into 15 distinct groups and the 180 accessions into four distinct groups in the... |

| ABSTRACT Lettuce seedlings used on hydroponic cultivation (NFT) are usually produced in trays with small volume, requiring two transplants: from tray to nursery and then to the definitive place. The aim of this study was to verify lettuce performance under NFT system, using seedlings produced in trays with several cell volumes (50, 40, 35, 31, 30, 29, 27, 20 and 10 cm³ cell-1). The tray volumes are considered treatments. The experimental design was completely randomized blocks, with four replicates. Seedlings were transplanted directly to the definitive profile, except those ones produced in 10 cm³ cell-1. Two harvests were performed, at 22 and 29 days after transplant (DAT). We evaluated number of senescent leaves, total number of leaves, shoot fresh... |

| O objetivo deste trabalho foi caracterizar genotipicamente, e construir o mapa de ligação e mapear locos associados a características quantitativas (QTL) de desempenho e carcaça no cromossomo 5 de linhagens brasileiras galinhas. Utilizou-se uma população F2 CTCT, resultante do acasalamento entre machos da linhagem de postura CC e fêmeas da linhagem de corte TT. Um total de 356 animais foi genotipado com 11 marcadores microssatélites. A caracterização genotípica foi realizada pela estimação dos seguintes parâmetros genotípicos: conteúdo de informação polimórfica (0,45-0,69), heterozigosidades observada (0,48-1,00) e esperada (0,48-0,74), e número de alelos por loco (3-5). Empregou-se o mapeamento por intervalo combinado à modelagem fenotípica por modelo... |
