Parametric model based assessment of genotype×environment interactions for grain yield in durum wheat under irrigation
The objectives of this study were to assess the genotype (G) by environment (E) interaction of grain yield of durum wheat(Triticum durum Desf.) based on parametric models, additive main effects and multiplicative interaction (AMMI) and joint linear regression models; and compare the relative efficiency of the two models in explaining the GE effects. Twenty-three genotypes were evaluated across ...
متن کاملAssessment of Storage and Temperature on Egg Physical Qualities for Peak Production in Hyline Chickens
The aim of the study was to evaluate the effect of storage and temperature on egg physical quality in Hyline chickens line. A total of 150 eggs from College of Natural Resources farm were sampled for the present experiment. About 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚C; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚C; relative hu...
متن کاملGenotype x environment interaction as it relates to egg production in turkeys (Meleagris gallopavo).
Genotype x environment (GxE) interactions can reduce the accuracy of a model to predict the performance of an animal and have an undesirable influence if not accounted for when estimating breeding values. Consequently, identification of these GxE is necessary when considering a turkey breeding program. Reranking based on the genetic prediction of turkey egg production, fertility, and hatchabili...
متن کاملA model for individual egg production in chickens.
Our primary objective was to improve on an existing model for the individual weekly egg production curve by modeling the curve as a sum of logistic functions: one for the increasing phase of production and a sum for the decreasing phases. To illustrate the model, we used four data sets from two pairs of individuals. For these data, the model consisted of an increasing phase and a single decreas...
متن کاملInteractions between diet composition and genotype of broiler chickens.
Day-old male broiler chickens of fat line (FL) and lean line (LL) (Leclercq et al., 1980) were obtained from INRA (Nouzilly, France). From two weeks of age onwards, both lines were divided into 2 groups, each receiving 1 of 2 isoenergetic diets with substitutions between fat and protein and a constant gross energy and carbohydrate level (low protein diet (LP): 126 vs 242 g protein/kg and low fa...
