Mapping QTL for grain yield and plant traits in a tropical maize population
The genetic dissection of quantitative traits in crops
(Pontificia Universidad Católica de Valparaíso, 2010)
QTL for percentage of carcass and carcass parts in a broiler x layer cross
P>An F(2) experimental population, developed from a broiler layer cross, was used in a genome scan of QTL for percentage of carcass, carcass parts, shank and head. Up to 649 F(2) chickens from four paternal half-sib families ...
Utilização de transformações não-parametricas no ajuste de dados de contagem de carrapatos utilizados no mapeamento de QTL.
(In: CONGRESSO BRASILEIRO DE GENÉTICA , 51., 2005, Águas de Lindóia. Lindóia: SBG, 2005., 2014)
Patterns of longevity and fecundity at two temperatures in a set of heat-selected recombinant inbred lines of Drosophila melanogaster
Quantitative trait loci (QTL) were mapped for longevity and fecundity at two temperatures, 20 and 30 °C, in two sets of recombinant inbred lines (RIL) highly differing in thermotolerance. Early fecundity (EF) and longevity ...
Mapeamento de QTL nos cromossomos 24 e 29 para medidas de peso, resistência a carrapato e estresse térmico em uma população F2 (Gir X Holandês)
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Genética Evolutiva e Biologia Molecular, 2009-07-13)
In the latest years, Brazil became one of the most important countries regarding the production and exportation of animal-based food. Improvements on the sanitary conditions and animal research applied to animal production ...
Composite interval mapping and mixed models reveal QTL associated with performance and carcass traits on chicken chromosomes 1, 3, and 4
Interval mapping (IM) implemented in QTL Express or GridQTL is widely used, but presents some limitations, such as restriction to a fixed model, risk of mapping two QTL when there may be only one and no discrimination of ...
QTL affecting body weight in a candidate region of cattle chromosome 5
(Sociedade Brasileira de Genética, 2003-01-01)
The objective of this work was to identify QTLs for liveweight in a candidate region of bovine chromosome 5. Half-sib families from two lines, one traditional and the other new, of Canchim beef cattle (5/8 Charolais + 3/8 ...
A mixed model QTL analysis for sugarcane multiple-harvest-location trial data
(SPRINGERNEW YORK, 2012)
Sugarcane-breeding programs take at least 12 years to develop new commercial cultivars. Molecular markers offer a possibility to study the genetic architecture of quantitative traits in sugarcane, and they may be used in ...
