2. Morpho-agronomic characterization and genetic divergence among pepper accessions
ABSTRACT The germplasm characterization and the analysis of genetic divergence are fundamental requirements to determine the genetic diversity available and peppers have considerable variability not most explored and quantified. Thus, the aim of this study was to characterize morphological and agronomically pepper accessions and their genetic divergence. The

3. Image phenotyping of lettuce germplasm with genetically diverse carotenoid levels
ABSTRACT Developing biofortified foods such as lettuce is a frequent goal of breeding programs. One obstacle to the success of these efforts is the high temporal and financial cost of determining leaf constituents. Image phenotyping has been increasingly used in crop breeding, but not in lettuce breeding. Until now, the use of image phenotyping to indirectly

4. Paclobutrazol application in potted ornamental pepper
RESUMO Dentro da variabilidade genética no gênero Capsicum há plantas com grande potencial ornamental, mas com altura desconforme da exigida pelo mercado. A aplicação de paclobutrazol (PBZ), retardante de crescimento e inibidor das giberelinas, é uma alternativa para reduzir a altura das plantas. O objetivo foi avaliar o efeito de diferentes concentra�

6. Genetic variability revealed by microsatellite markers in a germplasm collection of Jatropha curcas L. in Brazil: an important plant for biofuels
Abstract We evaluated the genetic variability of a collection of Jatropha curcas germplasm, represented by 93 accessions, using microsatellite markers. Among the 60 markers tested, five of them detected polymorphisms, with a total of 11 alleles and mean of 2.2 alleles per loci. These five markers enabled the quantification of genetic variability through esti

8. Chemical diversity of accessions of the in vivo germplasm bank of Varronia curassavica (Jacq.)
ABSTRACT. Varronia curassavica (Jacq.) is a shrub and perennial plant native to Brazil that has therapeutic, anti-inflammatory and cicatrizing properties. The objective of this work was to study the chemical diversity of the native populations of this species maintained in the in vivo germplasm bank from Montes Claros, Minas Gerais, Brazil. The essential oil

11. Morphological characterization of Coelogyne spp for germplasm conservation of orchids
ABSTRACT Orchid is one of the ornamental plant that has a high aesthetic value. Efforts to increase the quality of orchids can be done by genetic improvement through crossing. The first step to success in orchid crossing requires information on morphological characters of the prospective parents. This study aims to determine the similarity of six species of

12. Genetic parameters, path analysis and indirect selection of agronomic traits of cassava germplasm
Abstract: This study aimed to estimate genetic parameters and correlations between morphological, agronomic and root quality traits of cassava plants, as well as to study cause and effect relationships through path analysis. A total of 814 genotypes were evaluated from 2011 to 2015. The joint analysis of the data was performed by the mixed models approach. T
