1. Selection strategies in a segregating passion fruit population aided by classic and molecular techniques
ABSTRACT Combining the use of agronomic, disease-resistance, and molecular informationcan greatly contribute to genetic progress in breeding programs. This study was developed to estimate the genetic distance between genotypes derived from backcrosses and their parents using morphoagronomic and molecular information and information pertaining to resistance t

2. Genome composition and pollen viability of Jatropha (Euphorbiaceae) interspecific hybrids by Genomic In Situ Hybridization (GISH)
Abstract Interspecific hybridization is required for the development of Jatropha curcas L. improved cultivars, due to its narrow genetic basis. The present study aimed to analyze the parental genomic composition of F1 and BC1F1 generations derived from interspecific crosses (J. curcas/J. integerrima and J. curcas/J. multifida) by GISH (Genomic In Situ Hybrid

4. Multiple nesting attempts and long breeding seasons of Mimus gilvus (Aves: Mimidae) in southeastern Brazil
ABSTRACT This study describes aspects of the life history of the Tropical Mockingbird Mimus gilvus (Vieillot, 1808), including the breeding period, clutch size, nestlings and a list of plants used for nesting. Nests were monitored in an area of Restinga (sand-coastal plain) habitat in a protected area in southeastern Brazil. The data from 181 nests during fi

5. Relationship between meiotic instability and fertility in F2 generation Arabusta coffee plants
ABSTRACT Parental plants, an F1 interspecific hybrid and the F2 generation from Arabusta coffee plants were investigated for meiotic behavior and viability of pollen to understand part of their reproductive biology that affects their possible use in coffee breeding programs. Both parental plants (C. canephora var. Robusta 4x and C. arabica var. dihaploid Bou

6. Selection of squash “Menina Brasileira” carrying the allele “Bush” with high yield potential
RESUMO Objetivou-se introduzir o alelo Bush, de cultivares com hábito de crescimento tipo “moita”, em acessos de Cucurbita moschata e selecionar os melhores cruzamentos quanto ao potencial produtivo e ao formato de fruto padrão “menina brasileira” por meio da capacidade geral (CGC) e da capacidade específica (CEC) de combinação. Para determinar

7. Evaluation of SSR and SNP markers in Rubus glaucus Benth progenitors selection
Resumo Amora de castilla (Rubus glaucus Benth) é um dos produtos com maior potencial de desenvolvimento agrícola Colômbiano, que combina características dos subgéneros Idaeobatus e Rubus. Apesar da sua reconhecida importância na geração de rendas para os pequenos produtores, este cultivo tem recebido pouco desenvolvimento tecnológico. Como resultad

8. Genetic variability in popcorn synthetic population
ABSTRACT. The Brazilian popcorn has low genetic variability and the successful development of advanced lines, new popcorn cultivars with high grain yield (GY) and expansion volume (PE) is dependent on parental selection and precise determination of heterotic groups. The aim of this study was to evaluate genetic variability and identify heterotic groups in sy

9. Suicide risk configuration system in a clustered clinical sample: a generalized linear model obtained through the LASSO technique
Objective: To identify clinical and sociodemographic factors that increase or decrease suicidal risk in a clinical sample of subjects seeking mental health care. Method: A cross-sectional study was performed at three health centers in Santiago, Chile. The Parental Bonding Instrument (PBI), Depressive Experience Questionnaire (DEQ), Outcome Questionnaire (O

10. Successful Identification of Duck Genome Region Determining Desirable Uniformity of Meat Performance Traits
ABSTRACT The objective of this study was to identify genome regions determining duck meat performance traits with possible small variation. In total, 368 crossbred ducks of F2 generation obtained from two parental lines: Pekin-type ducks of Polish origin (A55) and Pekin-type ducks of French origin (GL-30) were recorded. The following seven traits were analyz

11. Factors for determining dental anxiety in preschool children with severe dental caries
Abstract The aim of this study was to assess the clinical and socioeconomic indicators associated with dental anxiety in preschool children with severe dental caries. A total of 100 children between 3 and 5 years of age were selected during a dental screening procedure. The selection criteria were having at least one tooth with dental caries and a visible pu

12. Genetic structure from the oldest Jatropha germplasm bank of Brazil and contribution for the genetic improvement
ABSTRACT Jatropha is a potential oilseed crop, which requires mitigating factors such as the low genetic variability of the species. The solution runs through the research of Brazilian germplasm. Attention should be given to the germplasm of jatropha the north of Minas Gerais, because this is the oldest national collection and because this region may be a re
