Biodiesel; DNA marker; Genetic divergence; Oleaginous seeds

The oleaginous species Jatropha curcas (Euphorbiaceae) exhibits significant potential as a source of biodiesel, but the scarcity of information regarding genetic variability within the species limits its possible exploitation. We examined the genetic diversity and relationships among 97 accessions of J. curcas originating from the Brazilian states ... more

Biodiesel; Center of domestication; Center of origin; Physic nut; Secondary center of diversity

Jatropha curcas is a multi-purpose plant species, with many advantages for biodiesel production. Its potential oil productivity is 1.9 t/ha, beginning the fourth year after planting. Nevertheless, limitations such as high harvest cost, lack of scientific konowledge and low profitability have prevented it from being utilized commercially. In order to provide information that could ... more

PE parameters; Plasma exchange (PE); Rescue treatment; Ricinism; Ricinus communis

The aim of this study was to investigate the selection of plasma exchange (PE) parameters and the safety of children with severe ricinism. The PE parameters and heparin dosage in 7 children with severe ricinism were recorded, and changes in the patients’ vital signs and coagulation function were monitored before and after PE. All patients successfully completed PE. The speed of blood flow ... more

Correlations between traits; Genetic divergence; Multivariate analysis; Plant breeding

The aim of this study was to use multivariate methods and Pearson and partial correlations to disregard phenotypic characteristics that contribute little to differentiation between Brachiaria ruziziensis genotypes. Eighty-one genotypes of B. ruziziensis were assessed in completely randomized blocks with three replications. Ten phenotypic characteristics were assessed: ... more

Coffea arabica; Genetic divergence; Multivariate analysis; Plant breeding

In a coffee plantation of a coffee ‘Acaiá’ cultivar (Coffea arabica), on the Midwest of Minas Gerais in Capitólio city, a different kind of coffee tree was found (1989), possibly due to a mutation. It presented larger leaves and grains than those of conventional coffee trees and was named as “Big Coffee VL.” The aim of this study was to estimate the ... more

Genetic divergence; Microsatellite marker; Specialty maize; Zea mays

In view of the narrow genetic base of popcorn, probably due to its evolution by selection from flint maize types alone, knowledge about genetic divergence is imperative for the formation of heterotic groups. Thus, our objective was to identify heterotic groups of popcorn lines; we did so by exploiting the representative genotype collection of the Active Popcorn ... more

Genetic divergence; Phaseolus vulgaris; Plant breeding

The common bean is widely distributed throughout Brazil and within Mato Grosso state. It has wide genetic variability and adaptability to various environmental conditions. We evaluated the genetic divergence and agronomic performance of common bean genotypes in order to initiate a bean breeding program in the region of Cáceres, MT. We included 58 genotypes (40 ... more
