1. 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

2. 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

3. First record of Isia alcumena, Spodoptera cosmioides and S. eridania (LEPIDOPTERA: NOCTUOIDEA) attacking Passion Fruit (Passiflora edulis Sims) in Brazil
Resumo O Brasil é considerado o centro de origem e de diversidade das passifloras, que apresentam importância, tanto para o consumo in natura, industrialização, uso medicinal e também como plantas ornamentais. As diferentes espécies de Passiflora hospedam uma grande diversidade de artrópodes que, ocasionando injúrias, podem causar danos econômicos

4. 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

5. IS THERE GENETIC VARIABILITY IN DWARF COCONUT ACCESSIONS PRESERVED IN BRAZIL?
RESUMO O coqueiro anão é a principal variedade para uso comercial no Brasil, que ocupa atualmente a quarta posição na produção mundial. No entanto, os genótipos utilizados no país ainda apresentam limitações e há necessidade de variabilidade genética. Este trabalho teve por objetivo estimar a variabilidade genética em acessos de coqueiro-anão c

6. Phenotypic and molecular characterization of apple (Malus × domestica Borkh) genetic resources in Greece
ABSTRACT: The phenotypic and genetic analysis of apple (Malus × domestica Borkh) genotypes is essential for breeding species. Information on the morphology and genetic structure of apple offers significant help for germplasm maintenance and selection of suitable material to breed superior cultivars. This study shows the results of an investigation on the mo

7. Diallel analysis and genetic differentiation of tropical and temperate maize inbred lines
Abstract This study aimed to evaluate hybrids obtained by the cross among temperate × tropical elite maize lines, and to determine the genetic diversity and population differentiation of these inbred lines. Forty-nine hybrids were evaluated for seed yield, plant and ear heights, and for severity of Phaeosphaeria maydis and Exserohilum turcicum in four envir

8. Genetic diversity in Brazilian soybean germplasm
Abstract Genetic diversity is an essential factor for the success of any plant breeding program and should be considered to ensure genetic gain through breeding. In Brazil, research on the genetic diversity and population structure of soybean is required since the species is an important commodity of the country. The study addressed the genetic diversity and

9. Genetic diversity of a Paspalum notatum Flügge germplasm collection
ABSTRACT The objective of this study was to assess the genetic diversity among accessions of Paspalum notatum based on morphological marker traits and identify those morphological traits that contribute most to the variability among accessions. Fifty-three accessions were evaluated for the following traits: length, width, color, and pubescence of sheath; len

10. Episomal detection of Banana streak OL virus in single and mixed infection with Cucumber mosaic virus in banana 'Nanicão Jangada'
Banana streak virus (BSV) and Cucumber mosaic virus (CMV) are commonly found in all banana growing-areas of the world. These viruses cause diseases that lead to yield reduction and constrain plant breeding and distribution of Musa germplasm. Most of the diagnostic methods targeting BSV can generate dubious results because of the considerable genetic and sero

11. Morphological phenotypic dispersion of garlic cultivars by cluster analysis and multidimensional scaling
Multivariate techniques have become a useful tool for studying the phenotypic diversity of Germplasm Bank accessions, since they make it possible to combine a variety of different information from these accessions. This study aimed to characterize the phenotypic dispersion of garlic (Allium sativum L.) using two multivariate techniques with different objecti

12. Diversidade genética em germoplasma de arroz japonês utilizando marcadores moleculares e agromorfológicos / Genetic diversity of Japanese rice germplasm using molecular markers and agromorphological traits
A caracterização e o entendimento da diversidade e estrutura genética de acessos armazenados em bancos de germoplasma é importante para a sua efetiva utilização em programas de melhoramento. Neste trabalho, 192 acessos japoneses de arroz pertencentes ao Banco de Germoplasma do Departamento de Genética da ESALQ/USP foram caracterizados por 23 descritor
