1. As plantas comestíveis no Brasil dos séculos XVI e XVII segundo relatos de época
Resumo Este trabalho objetivou estudar a flora comestível do Brasil nos séculos XVI e XVII a partir dos textos de 18 autores que estiveram no país durante este período. As plantas citadas foram identificadas por similaridade a partir das descrições textuais e imagens disponíveis nas obras estudadas, considerando a origem, área de ocorrência e nome p

2. Popcorn germplasm resistance to fungal diseases caused by Exserohilum turcicum and Bipolaris maydis
ABSTRACT Compared with the common corn, popcorn shows greater susceptibility to pests and diseases occurrence, being the use of resistant cultivars the most efficient strategy. In this regard, Germplasm Banks deserve special attention because they contain accessions that can be used as sources of resistance in breeding programs. The State University of North

3. Genetic diversity assessed by microsatellite markers in sweet corn cultivars
Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in te

4. Phenotypic and molecular characterization of corn hybrids released from 1980 to 2000
O acesso e o uso da variabilidade genética de uma cultura são as bases do melhoramento de plantas. Em milho, um grande e diverso pool gênico permite a manipulação de diferentes genótipos. No entanto, a diversidade genética do germoplasma tropical ainda é pouco estudada. Com o objetivo de analisar a amplitude da variabilidade genética em 15 híbridos

5. Capacidade de combinação e depressão por endogamia em populações de milho crioulo
The maize landraces are genotypes that have special features like wide genetic variability, which is noticeable through the color of grain, plant architecture and yield of their representatives. By presenting these different qualitative characteristics becomes important to perform a quantitative characterization of these genotypes for use in maize pre-breedi

6. Mapeamento de QTL para produção de grãos e caracters de planta em milho tropical utilizando marcadores microssatelites / Mapping QTL for grain yield and plant traits using microsatellite markers in a tropical maize population
Most of important agricultural and economical traits in maize are under the control of several gene loci, named quantitative trait loci (QTL). The possibility of using molecular markers and the statistic-genetic models made possible the mapping of these gene loci that affect such traits. Little focus has been given to QTL mapping study in populations derived

7. Melhoramento de milho para o cerrado do Estado de Tocantins / Corn breeding for the cerrado in the state of Tocantins
Os objetivos deste trabalho foram selecionar populações genitoras de milho eficientes na absorção e utilização de fósforo na produção de grãos, em condições de alta temperatura em solos de cerrado, na safrinha; avaliar o potencial de cultivares comerciais de milho como genitores para programas de melhoramento em estresse de fósforo; comparar o c

8. Efeito do Helminthosporium turcicum Pass. em duas linhagens de milho (Zea mays L.), uma resistente e outra susceptivel e nas gerações derivadas desses germoplasmas
A resistant 53 maize line. a susceptible 53 l1ne to Northern corn leaf blight caused by HeZminthospopium tucicum and related crosses were studied. The parental lines ditions for the development of tha pathogen. The six populations were evaluated in the Experimental Area of the UNICAMP in 1976/77. in a split-plot design with four repl! cations. The plots corr

9. Long-range patterns of diversity and linkage disequilibrium surrounding the maize Y1 gene are indicative of an asymmetric selective sweep
Both yellow and white corn occurs among ancestral open pollinated varieties. More recently, breeders have selected yellow endosperm variants of maize over ancestral white phenotypes for their increased nutritional value resulting from the up-regulation of the Y1 phytoene synthase gene product in endosperm tissue. As a result, diversity within yellow maize li

10. Development of a Core RFLP Map in Maize Using an Immortalized F(2) Population
A map derived from restriction fragment length polymorphisms (RFLPs) in maize (Zea mays L.) is presented. The map was constructed in an immortalized Tx303 X CO159 F(2) mapping population that allowed for an unlimited number of markers to be mapped and pooled F(3) seed to be distributed to other laboratories. A total of 215 markers consisting of 159 genomic c

11. A High-throughput AFLP-based Method for Constructing Integrated Genetic and Physical Maps: Progress Toward a Sorghum Genome Map
Sorghum is an important target for plant genomic mapping because of its adaptation to harsh environments, diverse germplasm collection, and value for comparing the genomes of grass species such as corn and rice. The construction of an integrated genetic and physical map of the sorghum genome (750 Mbp) is a primary goal of our sorghum genome project. To help
