Marked-assisted genetic improvement of agricultural species exploits statistical dependencies in the joint distribution of marker genotypes and quantitative traits. An issue is how molecular (e.g., dense marker maps) and phenotypic information (e.g., some measure of yield in plants) is to be used for predicting the genetic value of candidates for selection. Multiple regression, selection index ...

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...

quantitative trait loci (qtl) affecting milk production traits on bovine chromosome 6 close to the opn gene location have been identified through several whole genome scans. opn is a phosphoprotein, synthesized in a variety of tissues and cells and secreted into body fluids. in this study, dna was isolated from blood samples collected from 398 holstein cows in tehran and esfahan provinces. dna ...

this study was conducted to detect polymorphism of gene bmp15, a member of transforming growthfactor β (tgfβ) family which has a crucial role in controlling the ovarian follicles development,ovulation rate and fertility. samples were randomly selected from 91 najdi goats in 3 geographicallocations, northwest, southeast and center of khuzestan province. after dna extraction, amplification of235 ...

Marker-assisted selection holds promise for highly influencing tree breeding, especially for wood traits, by considerably reducing breeding cycles and increasing selection accuracy. In this study, we used a candidate gene approach to test for associations between 944 single-nucleotide polymorphism markers from 549 candidate genes and 25 wood quality traits in white spruce. A mixed-linear model ...
