This study aimed to evaluate the genetic variability of the teak germplasm bank, using morphological traits and inter-simple sequence repeat molecular markers. Thirty clones were evaluated in a randomized complete block design with three replicates, and each plot was composed of three plants. A joint analysis of quantitative and qualitative variables was performed using the Gower algorithm. ... more

The aims of this study were to assess the linear relationships between agronomic and nutritional traits and to identify promising traits for indirect selection in early and super-early maturing maize genotypes. Two trials were run in the 2009/2010 agricultural year, each consisting of a randomized block design with three replications. One trial was run on 36 early maturing maize genotypes and ... more

Desmanthus is a genus of forage legumes with high nutritional value, productive potential, and ability to obtain nitrogen in association with diazotrophic bacteria. The use of accurate techniques for genotype identification and characterization is essential for breeding programs. Morphological markers are widely used to know the genetic diversity and the molecular markers are fundamental in ... more

The success of recovery programs on degraded areas is dependent on the genetic material to be used, which should present heterozygosity and genetic diversity in native and recovered populations. This study was carried out to evaluate the model efficiency to enable the recovery of a degraded area of the Lower São Francisco, Sergipe, Brazil. The target species for this study was Schinus ... more

Jatropha; Microsatellite Repeats; Plant breeding; Polymorphism, Genetic; Seed Bank

Jatropha curcas L. is a highly promising oilseed for sustainable production of biofuels and bio-kerosene due to its high oil content and excellent quality. However, it is a perennial and incipiently domesticated species with none stable cultivar created until now despite genetic breeding programs in progress in several countries. Knowledge of the genetic structure and diversity of the species ... more

The Alcantarea patriae is a Bromeliaceae endemic to the inselbergs of the Atlantic Forest. This taxon, described in the year of 2007 by Versieux & Wanderley, presents restricted and fragmented distribution outside conservation units. Studies to evaluate the genetic structure of its populations can contribute to the conservation and management strategies for the species. In this study, 31 ... more

Knowledge of genetic diversity among genotypes and relationships among elite lines is of great importance for the development of breeding programs. Therefore, the objective of this study was to evaluate genetic variability based on the morphoagronomic and molecular characterization of 18 elite popcorn (Zea mays var. everta) lines to be used by Universidade Estadual de Maringá breeding programs ... more

Genes, Chloroplast; Molluginaceae; Phylogeny; Polymorphism, Genetic

The family Molluginaceae (order Caryophyllales) is considered polyphyletic based on the photosynthetic pathway, C evolution, and phylogeny of the family. This inference was made based on photosynthetic, anatomical, and molecular datasets. The generic circumscription of this family has greatly been changed owing to the placement of several of its genera into the Caryophyllaceae, Microteaceae, ... more

Chili pepper (Capsicum chinense) is a great economic important culture on the State of Amazonas, and it represents, approximately, a production of 1.9 thousand tons per year. It is one of the hosts of Colletotrichum genus in the North region of Brazil. The aim of the study was to differentiate and to identify isolates of Colletotrichum collected from C. chinense in Amazon. Molecular ... more

Sickle cell disease shows several clinical manifestations in distinct levels of severity. This heterogeneity is due to the haplotype variability associated with the HbS gene, levels of fetal hemoglobin and environmental conditions, which modify the disease expression. Science community believes that the presence of a polymorphism in the CCR5 gene, which is related to chronic inflammatory state ... more
