13. 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

14. Desenvolvimento e uso de marcadores SSR E DArT para estudos de diversidade genética em macadâmia (Macadamia integrifolia) / Development and use of SSR and DArT genetic markers to study genetic diversity in macadamia (Macadamia integrifolia)
A macadâmia (Macadamia integrifolia Maiden &Betche) é uma nogueira arbórea originária das florestas tropicais australianas. Sua distribuição natural ocorre por quase toda a costa leste da Austrália. No Brasil, foi introduzida em 1931, mas sua expansão aconteceu a partir da década de 70. As variedades comerciais são originadas de duas espécies, Mac

15. Development of an SSR-based identification key for Tunisian local almonds
Ten simple sequence repeat (SSR) loci were used to study polymorphism in 54 almond genotypes. All genotypes used in this study originated from almond-growing areas in Tunisia with different climatic conditions ranging from the sub-humid to the arid and are preserved in the national collection at Sidi Bouzid. Using ten SSR, 130 alleles and 250 genotypes were

16. Genetic architecture of purple pigmentation and tagging of some loci to SSR markers in pearl millet, Pennisetum glaucum (L.) R. Br.
This report describes the construction of integrated genetic maps in pearl millet involving certain purple phenotype and simple sequence repeat (SSR) markers. These maps provide a direct means of implementing DNA marker-assisted selection and of facilitating "map-based cloning" for engineering novel traits. The purple pigmentation of leaf sheath, midrib and

17. Desenvolvimento de marcadores microssatélites e caracterização da diversidade genética molecular de acessos de alho (Allium sativum L.) / Development of microsatellite markers and characterization of molecular genetic diversity among garlic (Allium sativum L.) accessions
Garlic is an important crop not only for its culinary attractiveness, but also because of a huge number of medicinal properties. The genetic resources in germplasm require characterization by morphological traits and molecular markers to be effectively used in breeding programs. A novel set of 16 SSR loci specific to garlic were developed. Ten loci were poly

18. Diversidade cromossômica e molecular no gênero Astyanax (Characiformes: Characidae) / Chromosomal and molecular diversity in the genus Astyanax (Characiformes: Characidae)
The origin of the genus Astyanax, one of the most specious genera of the family Characidae is appointed as polyphyletic, with its current taxonomic status Incertae sedis.Morphologic, genetic and phylogeographic studies contribute to a better knowledge on the genus, which is considered a model. In this work, several species of different locations were studied

19. Seleção genômica ampla e novos métodos de melhoramento do milho / Genome wide selection and new methods of maize breeding
The evaluation for nutrient efficiency use (UE) generally use destructive methods of the plant, not allowing, depending on the population genetic structure, using those identified as superior in hybridizations. Consequently, there is a reduction in the potential gains with selection. Additionally, some conventional breeding methods, such as the recurrent sel

20. Genetic diversity analysis of common beans based on molecular markers
A core collection of the common bean (Phaseolus vulgaris L.), representing genetic diversity in the entire Mexican holding, is kept at the INIFAP (Instituto Nacional de Investigaciones Forestales, Agricolas y Pecuarias, Mexico) Germplasm Bank. After evaluation, the genetic structure of this collection (200 accessions) was compared with that of landraces from

21. Development and validation of SSR markers for Coffea arabica L.
With the objective of developing new SSR markers for Coffea arabica, two enriched genomic libraries with probes (GT)15 and (AGG)10 were constructed. A total of 835 clones were sequenced and 756 presented good quality sequences. Redundant sequences were observed for 113 clones (14.94%). SSRs were found in 287 clones (38%). An estimated size of 417.5Kb of the

23. Study of simple sequence repeat markers from coffee expressed sequences associated to leaf miner resistance.
The objective of this work was to identify expressed simple sequence repeats (SSR) markers associated to leaf miner resistance in coffee progenies. Identification of SSR markers was accomplished by directed searches on the Brazilian Coffee Expressed Sequence Tags (EST) database. Sequence analysis of 32 selected SSR loci showed that 65% repeats are of tetra-,
