چکیده
ABSTRACT Mixed models and multivariate analysis are powerful tools for selecting superior genotypes in plant breeding programs. The BLUP (best linear unbiased prediction) method has been used to predict genetic values without environmental effects. Furthermore, the FAI-BLUP (ideotype-design index) procedure is especially valuable because of multiple-trait selection. This study aimed determine potential advanced wheat generations using REML/BLUP combination with techniques selection genotypes. experiment consisted eleven (Triticum aestivum L.) experimental design was randomized blocks, three replications.

Estimation of Genetic Parameters of Yield and Yield Traits in Wheat Genotypes under Rainfed Conditions
Development of superior crop varieties is the prime objectives of all plant breeding programs. To determine genetic variability, heritability and genetic advance, 24 elite bread wheat lines were planted in randomized complete block design with three replications at the University of Agriculture, Peshawar under rainfed conditions. Data were recorded on days to heading, days to maturity, plant he...
متن کامل14. Multiple Trait Selection
Improvement in the efficiency and quality of animal production can be achieved by improving several characteristics simultaneously. For example, we may want to breed the ideal dairy cow that produces not only a lot of milk, but also with a high percentage of components like fat and especially protein. In addition, such high producing animals should preferably have no fertility problems, not suf...
متن کاملMultiple-trait genomic selection methods increase genetic value prediction accuracy.
Genetic correlations between quantitative traits measured in many breeding programs are pervasive. These correlations indicate that measurements of one trait carry information on other traits. Current single-trait (univariate) genomic selection does not take advantage of this information. Multivariate genomic selection on multiple traits could accomplish this but has been little explored and te...
متن کاملIdentification of adapted genotypes in sesame lines based on multi-trait selection
Identification of genotypes adapted to a particular region is of special interest to breeders and plant geneticists. In order to identify adapted genotypes in sesame lines based on multi-trait selection, an experiment was conducted in a completely randomized block design with four replications at Moghan Agricultural Research Station of Ardabil Agricultural and Natural Resources Research and Edu...
