13. Genetic divergence in basil cultivars and hybrids
RESUMO O manjericão é uma erva aromática que se destaca por possuir importância econômica. É consumido in natura e também utilizado na obtenção de óleo essencial. O cultivo desta espécie em diversas regiões do mundo permitiu que surgissem variações mediante cruzamentos naturais e euploidia, ocasionando a ampla variabilidade genética existente.

14. Genetic diversity among red mombin fruits in the Southwest of Goiás
ABSTRACT The identification of productive plants with fruits of desirable characteristics contributes to the optimization of commercial crops of red mombin fruits. The aim of this work was to evaluate the genetic diversity among the provenance of red mombin of two municipalities of the state of Goiás. The fruits were harvested at ripening stage 3 and transp

15. Agronomic performance and genetic dissimilarity of second-harvest soybean cultivars using REML/BLUP and Gower’s algorithm
ABSTRACT The cultivation of second-harvest with soybean crop after first-harvest with maize crop has become an alternative to aggregate income to farmers in the South region of Brazil. However, there is little information about this cropping system in this region. The aims of this study were to: (i) evaluate the agronomic performance of soybean (Glycine max

16. Genetic variability of the components of seed yield in interspecific hybrids of Paspalum
ABSTRACT This study aimed to determine the variability and expression of the components of seed yield in twenty-three apomictic Paspalum plicatulum × Paspalum lepton hybrids and two male parent plants (P. lepton). We used a randomized block design with genotypes individually arranged into ten blocks. The variables were: number of total tillers/plant, number

17. Adaptability, stability, and genetic divergence of conilon coffee in Alto Suaçuí, Minas Gerais, Brazil
Abstract The objective of this study was to describe the genetic parameters, adaptability, and stability of clones from the Coffea canephora variety ‘Vitória Incaper 8142’, and the genetic divergence between them. Following 12 and 24 months of plant growth, several traits were evaluated, including stem diameter, plant height, canopy diameter, number of

18. Characterization of the Fruit Pulp of Camu-Camu (Myrciaria dubia) of Seven Different Genotypes and Their Rankings Using Statistical Methods PCA and HCA
Due to the economic potential of camu-camu, considering its high concentration of vitamin C, the aim of this work was to evaluate the quality and genetic variability seven accessions of camu-camu conserved in genebank (BAG) of Embrapa Amazônia Oriental, in the state of Pará, Amazon region, Brazil. The fruits of camucamuzeiro were analyzed for physicochemic

19. Molecular characterization of arabica and Conilon coffee plants genotypes by SSR and ISSR markers
The molecular characterization of ten genotypes of the Coffea arabica plants and of seven genotypes of C. canephora having interesting features for coffee breeding programs was carried to select the parents for breeding. A total of 40 SSR and 29 ISSR primers were used. The primers generated a total of 331 (307 polymorphic and 24 monomorphic) bands. Analysis

20. Joint analysis of phenotypic and molecular diversity provides new insights on the genetic variability of the brazilian physic nut germplasm bank
The genetic variability of the Brazilian physic nut (Jatropha curcas) germplasm bank (117 accessions) was assessed using a combination of phenotypic and molecular data. The joint dissimilarity matrix showed moderate correlation with the original matrices of phenotypic and molecular data. However, the correlation between the phenotypic dissimilarity matrix an

21. Diversidade em Psidium guajava L. por caracteres morfológicos, moleculares e citogenéticos / Diversity in Psidium guajava L. by morphological, molecular and cytogenetics
Guava (Psidium guajava L.) is one of the most economically important fruit crop from Myrtaceae family. Brazil is one of the largest producers of guava in the world, which is a potential crop in growth and profitability. Cross-pollination of the species and the existence of heterogeneous seminal propagation orchards result in variability, allowing the selecti

22. Genetic divergence between genotypes of forage peanut in relation to agronomic and chemical traits
The objective of this study was to evaluate the genetic divergence of forage peanut in relation to agronomic and chemical traits in both rainy and dry seasons. This experiment was conducted with genotypes from the Forage Peanut Active Germoplasm Bank located in Embrapa Acre. Eighteen genotypes of forage peanut were used: 12 genotypes of A. pintoi, four genot

23. Genetic diversity of American wild rice species
Studies on genetic diversity and genetic structure of natural populations are important in order to define strategies for in situ and ex situ conservation actions and for plant pre-breeding programs. Aiming to assess the genetic diversity and genetic structure of three wild American Oryza species with isozyme markers, 14 populations of the diploid O. glumaep
