1. Characterization of tomato generations according to a three-way data analysis
ABSTRACT Availability of a three-way data analysis to characterize two consecutive tomato (Solanum lycopersicum) generations is necessary to continue a plant breeding program with less uncertainty. The aim of this work was to analyze tomato fruit quality from F2 and F3 populations by two three-way data analysis: multiple factorial analysis (MFA) and generali

2. Post pollination events in a self-sterile hexaploid monoembryonic lineage of Handroanthus serratifolius (Vahl) S. Grose (Bignoniaceae)
ABSTRACT In diploid late-acting self-incompatible (LSI) species of Bignoniaceae, self-pollinated pistils show a marked delay in ovule penetration by pollen tubes, followed by delayed, but otherwise normal, initial stages of endosperm development and subsequent pistil abscission. Most polyploid species of Bignoniaceae are apomictic and set selfed fruits with

3. Biochemical and physical kernel properties of a standard maize hybrid in different TopCross™ Blends
ABSTRACT A pilot experiment was undertaken in order to examine high oil populations of maize (Zea mays L.) to be used as pollinators in TopCross blends with commercial ZP341 standard hybrid. Five high oil populations (HOPs) from the Maize Research Institute (MRI) gene bank were chosen for this research, according to their high grain oil content, synchrony be

4. Interspecific xenia and metaxenia in seeds and fruits of tomato
Xenia, the transmission of traits from the pollinizer to the female's tissues, is a phenomenon hitherto unknown in tomatoes. Here, we describe xenia effects on the seeds and fruits of Solanum lycopersicum, the tomato, elicited by S. galapagense. The wild tomatoes, such as S. galapagense, have highly pilose fruit surface and minute seeds, unlike the domestica

5. Depressao por endogamia em progenies de cajueiro anao precoce var. Nanum.
O plantio de sementes de cajueiro (Anacardium occidentale L.) causa desuniformidade no porte das plantas, na producao e peso das castanhas e na qualidade, cor e peso dos pedunculos. Com o objetivo de estimar a taxa de depressao por endogamia, foram obtidos dados de caracteristicas vegetativas e de producao aos 12, 18 e 29 meses de idade das plantas, em proge

6. Breeding systems in Echinococcus granulosus (Cestoda; Taeniidae) : selfing or outcrossing?
We used the PCR±SSCP method followed by sequencing in order to assess the genetic variability of coding and noncoding parts of the genome of Echinococcus granulosus (Cestoda; Taeniidae) and to test whether or not the parasite populations are mainly self-fertilizing. For this, we analysed a sample of 110 E. granulosus metacestode isolates collected from diff

7. Seleção, comportamento fenotípico e genotípico e desenvolvimento de uma nova cultivar de manjericão (Ocimum basilicum L.) para Sergipe. / Selection, phenotypical and genotypical behavior and development of a new basil (Ocimum basilicum L.) cultivar to Sergipe.
Basil is a medicinal, aromatic and spicy species with high commercial value. Actually, the production is based on the cultivation of a mix of chemical types and that cause production of low quality essential oil. The study of genetic parameters, which influence essential oil production and chemical constituents, contribute for development of cultivars with h

8. A bacterial artificial chromosome library for Biomphalaria glabrata, intermediate snail host of Schistosoma mansoni
To provide a novel resource for analysis of the genome of Biomphalaria glabrata, members of the international Biomphalaria glabrata Genome Initiative (biology.unm.edu/biomphalaria-genome.html), working with the Arizona Genomics Institute (AGI) and supported by the National Human Genome Research In

9. Analysis of general and specific combining abilities of popcorn populations, including selfed parents
Estimation of general and specific combining ability effects in a diallel analysis of cross-pollinating populations, including the selfed parents, is presented in this work. The restrictions considered satisfy the parametric values of the GCA and SCA effects. The method is extended to self-pollinating populations (suitable for other species, without the self

10. ImplicaÃÃes do nÃmero de intercruzamentos nas propriedades genÃticas de uma populaÃÃo segregante de feijoeiro / Implications of the number of intercrossings in the genetic properties of a common bean population.
In autogamus species, like common bean na usual question about the breeding program based on hybridization, in the necessity to intercross plants of the F2 generation. The objective of this research was to verify the effect of 0, 1 and 2 intercrossings on the genetic properties of a common bean segregating population derived from multiple crossings. A involv

11. Mutantes da via metabolica do acido aspartico em milho, obtidos atraves de cultura de tecidos
The essential amino acids lysine, threonine and methionine are derived from the aspartate family of amino acids in pIants. Since the cereaIs are devoid in at least one of these amino acids, the aspartate pathway has received great attention in the last recent years. Biochemical, moIecular and genetic studies has lead to a deep understand of the regulation of

12. Comportamento de mutantes de endosperma de milho (zea mays L.) em relação ao fuzarium moniliforme Sheld
A comparative study involving 11 different endosperm mutants of maize and their correspondent normal counterparts was carried out to study the effect of endosperm mutant genes on pathogenicity of F. moniliforme. The following mutants were studied: Shrunken (sh), shrunken-2 (sh2), floury (fl), brittle (bt) brittle-2 (bt2), waxy (wx), dull (du), sugary (su), s
