1. IAC Catuaí SH3 - a dwarf Arabica coffee cultivar with leaf rust resistance and drought tolerance
Abstract The cultivar IAC Catuaí SH3 was developed by the pedigree method, from the recombination of the coffee tree H 2077-2-5-46, of the Catuaí Vermelho germplasm, with accession IAC 1110-8, from the exotic cultivar BA10. Cultivar IAC Catuaí SH3 is high-yielding, resistant to coffee leaf rust and tolerant to drought.

2. Development of superior lines of papaya from the Formosa group using the pedigree method and REML/Blup procedure
ABSTRACT Developing superior lines based on a simultaneous response from many traits of agronomic importance is a fundamental strategy to expand papaya cultivar supply, mainly the much-needed cultivars belonging to group Formosa. Our goal was to associate the pedigree method with REML/Blup procedure to select plants of progenies F2:3 with superior agronomic

3. Assessment of genetic variation of 15 Thai elite rice cultivars using InDel markers
Abstract Many elite rice varieties have been developed in the last decades by Thai rice breeders. No information about the genetic gene pool of these elite rice varieties is available. This study evaluated the genetic relationship of 15 elite Thai rice cultivars using Indel markers. Of the 133 markers screened, 44 were polymorphic. The PIC scores ranged from

4. Environmental effects on performance of progeny from different Nellore sires in Brazilian semiarid region
RESUMO O objetivo deste trabalho foi avaliar a influência dos fatores ambientais sobre o desempenho das progénies de diferentes touros da raça Nelore no semiárido brasileiro. Informações de 741 animais foram coletadas de uma fazenda comercial localizada no municipio de Varzelândia-MG. Os animais eram filhos de 27 touros da raça Nelore e eram categori

5. Imputation of genetic composition for missing pedigree data in Serrasalmidae using morphometric data
ABSTRACT This study aimed to impute the genetic makeup of individual fishes of Serrasalmidae family on the basis of body weight and morphometric measurements. Eighty-three juveniles, belonging to the genetic groups Pacu, Pirapitinga, Tambaqui, Tambacu, Tambatinga, Patinga, Paqui and Piraqui, were separated into 16 water tanks in a recirculation system, with

6. Genealogical data in population medical genetics: field guidelines
This is a guide for fieldwork in Population Medical Genetics research projects. Data collection, handling, and analysis from large pedigrees require the use of specific tools and methods not widely familiar to human geneticists, unfortunately leading to ineffective graphic pedigrees. Initially, the objective of the pedigree must be decided, and the available

7. Penetrance rate estimation in autosomal dominant conditions
Accurate estimates of the penetrance rate of autosomal dominant conditions are important, among other issues, for optimizing recurrence risks in genetic counseling. The present work on penetrance rate estimation from pedigree data considers the following situations: 1) estimation of the penetrance rate K (brief review of the method); 2) construction of exact

8. Skew normal mixed models in microarray data generated from complex pedigrees / Modelos mistos normais assimÃtricos em dados de microarrays originados de pedigrees complexos / Modelos mistos normais assimÃtricos em dados de microarrays originados de pedigrees complexos / Skew normal mixed models in microarray data generated from complex pedigrees
Estimates of heritability for gene expression are scarce and commonly originated from family structures, in which the variability of responses among and within families are provided under a uniform covariance structure for related individuals, ignoring the known relationship among all individuals in the pedigree. Gauss-Markov normal mixed models are the usua

9. Juventude, arte e poesia: a constituiÃÃo histÃrica do CRIA â Centro de ReferÃncia Integral de Adolescentes / Youth, Art and poetry: the historical construction of CRIA - Centro de ReferÃncia Integral de Adolescentes
This research was used in Method History (arch-genealogy), to learn the meanings of teaching practices and proposals offered to young people who are integrated into programs and / or educational projects in a non-school institution. The empirical field was the CRIA â Centro de ReferÃncia Integral de Adolescentes, an NGO working since 1994 with artistic tra

10. Inclusion of genetic relationship information in the pedigree selection method using mixed models
We used a mixed model approach and computer simulation to evaluate the inclusion of parentage information as determined by the genealogy established in the pedigree method. The simulations were based on a purely additive genetic model for one quantitative trait of 20 unlinked segregating loci with equal effects and an allelic frequency of 0.5 for heritabilit

11. Quantitative-genetic study of muscle fibers of number and diameter in a male broiler line / Estudo genético-quantitativo de número e diâmetro de fibras musculares em linhagem macho de frangos
This research was conducted to estimate genetic and phenotypic parameters of muscle fibers of number, diameter and area, as well as of performace, carcass and meat quality traits in a male broiler line belonging to a program of selection of the type sib test, in which data from complete brothers of the individuals were selected, bred in a pedigree flock prov

12. Genetic evaluation of beef cattle composite / Avaliação genética de bovinos de corte compostos
Genetic groups were used to estimate the heterosis and its profile along generations in the population of Tropical Montana composite. The genetic groups evaluated were: pure breed animals, F1, other crossbreds and Tropical Montana composites. It was used a pedigree data to calculate each animal generation. The data were adjusted for the effects of total mate
