1. Genetic linkage map and mapping of the locus of biological nitrogen fixation inefficiency in cowpea
ABSTRACT. The objectives of the present study were to construct a cowpea genetic map using the F2 population resulting from the cross IC-1 x BRS Marataoã, based on single nucleotide polymorphism (SNP) markers, and to map the cpi gene, with additional reference to introgression with the consensus map of species, aiming to identify markers for assisted select

3. Mapping of QTL for aluminum tolerance in tropical maize
Abstract The objectives of this study were to map genomic regions associated with QTL for aluminum (Al) tolerance in maize and determine the phenotypic effects of tolerance loci. QTL analysis for Al tolerance was carried out in a population of F2:3 progenies resulting from a cross between the contrasting lines LT 99-4 and LS 04-2. SSR (Simple Sequence Repeat

4. Linkage and mapping of quantitative trait loci associated with angular leaf spot and powdery mildew resistance in common beans
Abstract Angular leaf spot (ALS) and powdery mildew (PWM) are two important fungi diseases causing significant yield losses in common beans. In this study, a new genetic linkage map was constructed using single sequence repeats (SSRs) and single nucleotide polymorphisms (SNPs), in a segregating population derived from the AND 277 x SEA 5 cross, with 105 reco

5. Evaluation of SRAP markers for mapping of Pisum sativum L.
Abstract Linkage maps have become important tools for genetic studies. With the aim of evaluating the SRAP (sequence-related amplified polymorphism) technique for linkage mapping in Pisum sativum L., a F2 mapping population derived from an initial cross between cvs. DDR11 and Zav25 were generated. A total of 25 SRAP primer combinations were evaluated in 45 F

6. Chromosomal localization of microsatellite loci in Drosophila mediopunctata
Drosophila mediopunctata has been used as a model organism for genetics and evolutionary studies in the last three decades. A linkage map with 48 microsatellite loci recently published for this species showed five syntenic groups, which had their homology determined to Drosophila melanogaster chromosomes. Then, by inference, each of the groups was associated

7. Fine mapping and single nucleotide polymorphism effects estimation on pig chromosomes 1, 4, 7, 8, 17 and X
Fine mapping of quantitative trait loci (QTL) from previous linkage studies was performed on pig chromosomes 1, 4, 7, 8, 17, and X which were known to harbor QTL. Traits were divided into: growth performance, carcass, internal organs, cut yields, and meat quality. Fifty families were used of a F2 population produced by crossing local Brazilian Piau boars wit

8. Mapa genético-molecular para Hevea brasiliensis e mapeamento de QTL s para características de impotância econômica / Genetic linkage map for H. brasiliensis and QTL s mapping for important economic traits
A seringueira é uma espécie de cruzamento misto e com um longo ciclo de vida, o que dificulta a geração de linhagens endogâmicas e, por consequência, a construção e integração de mapas de ligação usando as metodologias convencionais. A exemplo do que tem sido feito em outras espécies vegetais que apresentam limitações para a obtenção de linh

9. Model selection for quantitative trait loci mapping in a full-sib family
Statistical methods for mapping quantitative trait loci (QTLs) in full-sib forest trees, in which the number of alleles and linkage phase can vary from locus to locus, are still not well established. Previous studies assumed that the QTL segregation pattern was fixed throughout the genome in a full-sib family, despite the fact that this pattern can vary amon

10. 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

11. Marcadores moleculares microssatélites na investigação do genoma de Drosophila mediopunctata : desenvolvimento e construção de mapa genético de ligação / Microsatellite markers in the investigation of Drosophila mediopunctata genome : development and genetic linkage map construction
Drosophila mediopunctata, mosca não cosmopolita de distribuição neotropical e pertencente ao grupo tripunctata do subgênero Drosophila, é uma espécie utilizada por alguns grupos no Brasil como modelo em estudos com enfoque evolutivo. Abordagens que exploram a biologia da espécie, tais como a detecção de variação genética natural e a influência d

12. Genetic linkage maps of 'Pêra' sweet orange and 'Cravo' mandarin with RAPD markers.
The objective of this work was to construct linkage maps of 'Pêra' sweet orange [Citrus sinensis (L.) Osbeck] and 'Cravo' mandarin (Citrus reticulata Blanco) using RAPD markers and the pseudo-testcross strategy. The parents were chosen according to the resistance/susceptibility to citrus variegate chlorosis (CVC). The segregation of 176 markers was analyzed
