Quantitative trait loci underlying milk production traits in sheep.
Improvement of milk production traits in dairy sheep is required to increase the competitiveness of the industry and to maintain the production of high quality cheese in regions of Mediterranean countries with less favourable conditions. Additional improvement over classical selection could be reached if genes with significant effects on the relevant traits were specifically targeted by selecti...
متن کاملQuantitative trait loci mapping of panicle traits in rice
In this study 90 individuals of recombinant inbred lines (RILs) were developed by crossing subspecies of japonica rice cultivar, ‘Nagdong’ and an indica type cultivar, ‘Cheongcheong’. These individuals were used to identify the quantitative trait loci of panicle traits using SSR markers. A genetic linkage map was constructed using one hundred fifty four simple sequence repeat ...

متن کاملMapping quantitative trait Loci underlying fitness-related traits in a free-living sheep population.
We searched for quantitative trait loci (QTL) underlying fitness-related traits in a free-living pedigree of 588 Soay sheep in which a genetic map using 251 markers with an average spacing of 15 cM had been established previously. Traits examined included birth date and weight, considered both as maternal and offspring traits, foreleg length, hindleg length, and body weight measured on animals ...
متن کاملUdder Morphology and Machine Milking Ability in Dairy Sheep
This paper describes the particularities of the anatomy and morphology of the dairy sheep udder and the current implications on machine milkability. The sheep mammary gland is an exocrine epithelial gland mainly constituted of tubulo-alveolar parenchyma with alveoli and well differentiated cisterns. Two anatomical compartments are used for milk storage: alveolar and cisternal, the large-cistern...
