Efficiency of marker-assisted selection in the improvement of quantitative traits.
Molecular genetics can be integrated with traditional methods of artificial selection on phenotypes by applying marker-assisted selection (MAS). We derive selection indices that maximize the rate of improvement in quantitative characters under different schemes of MAS combining information on molecular genetic polymorphisms (marker loci) with data on phenotypic variation among individuals (and ...
متن کاملMore on the efficiency of marker-assisted selection
Computer simulations were used to study the efficiency of marker-assisted selection (MAS) based on an index combining the phenotypic value and the molecular score of individuals. The molecular score is computed from the effects attributed to markers by multiple regression of phenotype on marker genotype. The results show that in the first generation the ratio RE of the expected efficiency of MA...
متن کاملThe accuracy of marker-assisted selection for quantitative traits within populations in linkage equilibrium.
Using the concept of conditional coancestry, given observed markers, an explicit expression of the accuracy of marker-based selection is derived in situations of linkage equilibrium between markers and quantitative trait loci (QTL), for the general case of full-sib families nested within half-sib families. Such a selection scheme is rather inaccurate for moderate values of family sizes and QTL ...
متن کاملMarker-assisted selection efficiency in populations of finite size.
The efficiency of marker-assisted selection (MAS) based on an index incorporating both phenotypic and molecular information is evaluated with an analytical approach that takes into account the size of the experiment. We consider the case of a population derived from a cross between two homozygous lines, which is commonly used in plant breeding, and we study the relative efficiency of MAS compar...
متن کاملImproving Efficiency of DNA Marker Technology for Use in Marker-Assisted Selection
Molecular marker-assisted selection (MAS) is currently being used to accelerate the development of rice cultivars with improved cooking quality and blast resistance at the University of Arkansas Rice Research and Extension Center (UA RREC) in Stuttgart. A co-dominant simple sequence repeat (SSR) marker, RM 190, is used to predict cooking quality of the milled grain, and a new automation-friendl...
