Genetic correlations between performance at different racing distances in Thoroughbreds
(2006-11-01)
The aim of the present study was to estimate genetic correlations between time at different racing distances in Thoroughbred racehorses based on data provided by Turftotal Ltda. The traits evaluated were times in seconds ...
Genetic Variation in an International Provenance-Progeny Test of Pinus caribaea Mor. var. bahamensis Bar. et Gol., in São Paulo, Brazil
(J D Sauerlanders Verlag, 2008-01-01)
A combined provenance-progeny test of Pinus caribaea var. bahamensis was established in Paraguacu Paulista Experimental Station, São Paulo State, Brazil, in a "compact family" blocks design with 14 provenances, 2 to 10 ...
Genetic variability in open pollinated progenies of Jatropha curcas
(Ipef-inst Pesquisas Estudos Florestais, 2015-03-01)
The objective of the present work was to estimate the genetic parameters of morphological traits, such as plant growth, fruit and seed production; and oil content and also to provide a source of superior genetic material ...
Estimates of genetic parameters and cluster analyses for carcass and meat quality traits in birds
(Empresa Brasil Pesq Agropec, 2017-03-01)
The objective of this work was to estimate genetic parameters for bird carcass and meat quality traits, as well as to explore the genetic patterns of the breeding values of this population using cluster analyses. Data from ...
Genetic parameters for body weight in buffaloes (Bubalus bubalis) in Colombia using random regression models
(Elsevier B.V., 2013-12-01)
The objective of this research was to estimate (co) variance functions and genetic parameters for body weight in Colombian buffalo populations using random regression models with Legendre polynomials. Data consisted of ...
Genetic parameters for milk yield of Bubalus bubalis using unadjusted and adjusted milk production for days in milk
(2007-12-01)
The objectives of this study were to estimate genetic parameters for unadjusted and adjusted milk production for 270 and 305 days of lactation and, subsequently, to verify the coincidence of rank of 2%, 5%, 20% and 40% ...

(Pagepress Publ, 2007-01-01)
The objectives of this study were to estimate genetic parameters for unadjusted and adjusted milk production for 270 and 305 days of lactation and, subsequently, to verify the coincidence of rank of 2%, 5%, 20% and 40% ...
Random regression models to estimate test-day milk yield genetic parameters Holstein cows in Southeastern Brazil
(Elsevier B.V., 2009-07-01)
A total of 152,145 weekly test-day milk yield records from 7317 first lactations of Holstein cows distributed in 93 herds in southeastern Brazil were analyzed. Test-day milk yields were classified into 44 weekly classes ...
Evaluation of selection criteria in laying quail (Coturnix coturnix japonica)
(2019-09-01)
The primary aim of the commercial exploration of quail in Brazil is to increase egg production. The characteristics of the genetic groups used are not well known, making it difficult to increase eggs production. The objective ...
Evaluation of papaya genotypes using agronomic descriptors and estimation of genetic parametersDescritores agronômicos e parâmetros genéticos na avaliação de genótipos de mamoeiros
(2018-07-01)
In Brazil, the improvement of papaya agribusiness is correlated to the estimation of genetic parameters and evaluation of agronomic descriptors; thus enabling less favourable areas for the development and implementation ...
