Abstract: Winterhardiness is a complex trait that involves low temperature tolerance (LTT), vernalization sensitivity, and photoperiod sensitivity. Quantitative trait loci (QTL) for these traits were fi rst identifi ed using biparental mapping populations; candidate genes for all loci have since been identifi ed and characterized. In this research we used a set of 148 accessions consisting of advanced breeding lines from the Oregon barley (Hordeum vulgare L. subsp vulgare) breeding program and selected cultivars that were extensively phenotyped and genotyped with single nucleotide polymorphisms. Using these data for genome-wide association mapping we detected the same QTL and genes that have been systematically characterized using biparental populations over nearly two decades of intensive research. In this sample of germplasm, maximum LTT can be achieved with facultative growth habit, which can be predicted using a three-locus haplotype involving FR-H1, FR-H2, and VRN-H2. The FR-H1and FR-H2 LTT QTL explained 25% of the phenotypic variation, offering the prospect that additional gains from selection can be achieved once favorable alleles are fi xed at these loci. |

ABSTRACT.
Accurate and cost-effective DNA-based parentage assignment tools are relevant for genetic im-provement and conservation programs. Parentage-testing SNPs selected in commercial sheep breeds were evaluated in Creole sheep in Uruguay using information provided by the 600k SNP chip. Genotyping results indicated a high proportion of fixed and rare SNPs (21.98%; MAF<=0.001), and a relatively low proportion of highly polymorphic SNPs (25.86%; MAF>=0.3). Nevertheless, subsets of 72 and 93 SNPs of the most informative markers for parentage testing, reached probability exclusions of 0.9999 and 0.99999, with average MAF values of 0.43. Comparison of the genotypes of 34 ewe-lamb pairs showed that both subsets of SNPs successfully found correct/incorrect pairs. Although these are preliminary results they show the feasibility of using these SNPs for parentage verification in Creole sheep. This will help to correctly record the genealogy of the population in the future conservation plan. |
