Laying performance is an important economical trait of goose production. As laying performance is of low heritability, it is of significance to develop a marker-assisted selection (MAS) strategy for this trait. Definition of sequence variation related to the target trait is a prerequisite of quantitating MAS, but little is presently known about the goose genome, which greatly hinders the identi...

Leaf rust is amongst major biotic constraints of wheat (Triticum aestivum L.) having ability to cause substantial yield reductions worldwide. A continuous exploration for novel sources resistance pre-requisite its management. Objectives study were conduct evaluation 112 Pakistani landraces and 48 advanced lines/ cultivars at seedling stage with total 10 virulent pathotypes leaf rust, 3 from Pak...

This study aims to reveal the genotypic structure of four cattle breeds; Holstein (HS), Turkish Grey Steppe (TGS), Anatolian Black (AB) and East Red (EAR), raised in Turkey terms CD14, MBL, ITGB6, SLC11A1 TLR2 genes evaluate their usefulness Marker Assisted Selection (MAS). It also assesses whether loci associated with resistance diseases are suitable for phylogenetic analysis. Desired alleles ...

BACKGROUND The aim of this study was to estimate haplotype effects and then to predict breeding values using linear models. The haplotype based analysis enables avoidance of loosing information due to linkage disequilibrium between single markers. There are also less explanatory variables in the linear model which makes the estimation more reliable. METHODS Different methods and criteria for ...

The development of molecular techniques for genetic analysis has led to a great increase in our knowledge of cereal genetics and our understanding of the structure and behaviour of cereal genomes. These molecular techniques, in particular the use of molecular markers, have been used to monitor DNA sequence variation in and among the species and create new sources of genetic variation by introdu...

Within the framework of our cotton breeding program, we are using molecular markers to improve the efficiency of the introgression of fiber quality traits into a favorable genetic background. This effort relies on i) the development of a saturated genetic map of the cotton genome, ii) the identification of fiber quality QTLs, and iii) the marker-assisted introgression of favorable genomic regio...

Designs used for detecting QTL in livestock vary from experimental backcross and F2 populations to half-sib designs that use existing family structures within a commercial population. This contribution discusses how the initial design in which the QTL are detected affects: a) the implementation of MAS and b) the fine mapping of the QTL. The optimal approach depends on the livestock species and ...

Selection under the infinitesimal model Standard animal breeding techniques have been largely successful in improving the performance of domestic animals in the last century. The success of these techniques finds its roots in the theoretical work of Fisher and Wright who showed how selection, migration and mutation could be derived from the simple Mendelian laws. All that theory was then transf...

The photoperiodic sensitivity of soybean (Glycine max L.) is one the limiting factors affecting plant growth and yield. At higher latitudes, early flowering maturity with neutral reaction to photoperiods are required for adaptation plants long-day conditions. Currently, production distribution new varieties soybeans adapted widespread agricultural regions in northern Kazakhstan strong demand. E...
