13. Coupling linkage maps in F2 populations of carrot derived from two different crosses.
Linkage grouping and ordering AFLP markers analyses were performed for two different F2 populations of carrot (Daucus carota L.). Included were 277 and 242 dominant AFLP markers and 10 and 8 co-dominant markers assigned to the nine linkage groups of Brasilia x HCM and B493 x QAL F2 populations, respectively. The overall marker datasets, includjng repulsion a

14. Inheritance of coffee leaf rust reistance and identification of AFLP markers linked to the resistance gene.
The most important disease of Coffea arabica is coffee leaf rust caused by the fungus Hemileia vastatrix. The purpose of this study was to characterize the inheritance of coffee resistance gene(s) to race II of this pathogen and to identify and map molecular markers linked to this trait. Different populations were used: F2 (160 plants), BCr (20), and BCs (13

16. Genetic diversity in cultivated carioca common beans based on molecular marker analysis
A wide array of molecular markers has been used to investigate the genetic diversity among common bean species. However, the best combination of markers for studying such diversity among common bean cultivars has yet to be determined. Few reports have examined the genetic diversity of the carioca bean, commercially one of the most important common beans in B

17. Desenvolvimento de marcadores SSR, M-AFLP e SNP visando à integração de mapas genético-moleculares de Passiflora alata Curtis / Development of SSR, M-AFLP and SNP markers for linkage map integration of Passiflora alata Curtis
Embora não exista uma variedade comercial de maracujazeiro-doce (Passiflora alata Curtis), a fruta vem ganhando espaço no mercado brasileiro, justificando o uso de técnicas convencionais e moleculares no melhoramento da cultura. Nas espécies em que ocorre autoincompatibilidade e o cruzamento entre indivíduos é obrigatório, como nos maracujazeiros, nã

18. Mapeamento genético de cana-de-açúcar (Saccharum spp.) por associação empregando marcadores SSR e AFLP / Genetic mapping of sugar cane (Saccharum spp.) by association using SSR and AFLP markers
A cultura da cana-de-açúcar (Saccharum spp.) possui uma importância histórica e econômica para o Brasil. O agronegócio sucroalcooleiro vem experimentando forte expansão na última década não só no Brasil como também em todo o mundo em função, principalmente, da demanda por fontes de energia menos agressivas ao ambiente. Para atender a uma maior

19. Genetic variability of Five Periplaneta americana L. (Dyctioptera: Blattidae) populations in southwestern Colombia using the AFLP molecular marker technique
The genetic structure of five Periplaneta americana (L.) populations from three cities (Cali, Popayán and Buenaventura) located in southwestern Colombia was estimated using the AFLP molecular marker technique. A set of 174 loci were analyzed, 120 of which were polymorphic. Genetic diversity was estimated at different geographic levels for the total populati

20. SSR and AFLP based genetic diversity of soybean germplasm differing in photoperiod sensitivity
Forty-four soybean genotypes with different photoperiod response were selected after screening of 1000 soybean accessions under artificial condition and were profiled using 40 SSR and 5 AFLP primer pairs. The average polymorphism information content (PIC) for SSR and AFLP marker systems was 0.507 and 0.120, respectively. Clustering of genotypes was done usin

21. Genetic mapping of AFLP and retrotransposon-derived markers in sugarcane (Saccharum spp.) / Mapeamento genético de marcadores AFLP e de retrotransposons em cana-de-açúcar (Saccharum spp.)
No presente trabalho, AFLPs e marcadores baseados em retrotransposons foram utilizados para a construção de um mapa de ligação integrado em cana-de-açúcar. Dois retrotransposons encontrados no genoma da cana-de-açúcar, denominados SURE e Garapa, foram estudados. Os princípios da técnica NBS-profiling foram usados para gerar marcadores direcionados

22. Mapeamento de locos de resistência quantitativa da soja ao complexo de percevejos / Mapping of quantitative resistance loci from soybean to stink bug complex
O cultivo da soja em grandes áreas agrícolas e o plantio sucessivo em uma mesma área contribuíram significativamente para o aumento na incidência de insetospraga nessa cultura, causando danos crescentes à produção. Os percevejos sugadores de sementes são considerados uma das pragas de maior importância para a cultura da soja. Neste estudo, 286 plan

23. Mapeamento de locos de resistência quantitativa a Puccinia psidii Winter em uma progênie de irmãos completos de eucalipto / Mapping of quantitative resistance loci against Puccinia psidii Winter in a full-sib progeny of Eucalyptus
In Brazil, the eucalyptus rust, caused by Puccinia psidii Winter, stands out as the most important disease of eucalypts, mainly in southeastern Brazil. The use of resistant genotypes is the main control method, which makes the understanding of the genetic basis of resistance essential to the selection of resistant genotypes. In this study, an F1 progeny of 9

24. Use of AFLP and RAPD molecular genetic markers and cytogenetic analysis to explore relationships among taxa of the Patagonian Bromus setifolius complex
Bromus setifolius var. pictus (Hook) Skottsb., B. setifolius var. setifolius Presl. and B. setifolius var. brevifolius Ness are three native Patagonian taxa in the section Pnigma Dumort of the genus Bromus L. AFLP and RAPD analysis, in conjunction with genetic distance measurements and statistical techniques, revealed variation within this group and indicate
