Genotype by environment interaction in Nelore cattle from five Brazilian states
Records from 75,941 Nelore cattle were used to determine the importance of genotype by environment interaction (GEI) in five Brazilian states. (Co)variance components were estimated by single-trait analysis (with yearling weight, W450, considered to be the same trait in all states) and multiple-trait analysis (with the record from each state considered to be a different trait). The direct herit...
متن کاملGenotype by environment interaction for 450-day weight of Nelore cattle analyzed by reaction norm models
Genotype by environment interactions (GEI) have attracted increasing attention in tropical breeding programs because of the variety of production systems involved. In this work, we assessed GEI in 450-day adjusted weight (W450) Nelore cattle from 366 Brazilian herds by comparing traditional univariate single-environment model analysis (UM) and random regression first order reaction norm models ...
متن کاملestimation of genotype by environment interaction for production traits in iranian holstein cattle
in order to evaluation of genotype by environment interactions in holstein cows, iran was divided into cold, middle cold, temperate and hot climate regions. for this purpose used from 39570, 35813 and 18955 records for milk, fat and protein yields, respectively, to progeny test for 35 sires that have 50 daughters in each climate. the data were collected by the centre of breeding and improvement...
متن کاملFrom Genotype × Environment Interaction to Gene × Environment Interaction
Historically in plant breeding a large number of statistical models has been developed and used for studying genotype × environment interaction. These models have helped plant breeders to assess the stability of economically important traits and to predict the performance of newly developed genotypes evaluated under varying environmental conditions. In the last decade, the use of relatively low...
متن کاملGenotype by Environment Interaction for Milk Production Traits in Guernsey Cattle
Current methods for routine international evaluations are based on pre-processed information. This puts several restrictions on the method of analysis that can be used. For example, comparisons need to be made on genetic evaluation unit bases. Neighboring countries with similar production environments cannot be treated as genetically identical traits, and environmental variation within country ...
