Joint QTL linkage mapping for multiple-cross mating design sharing one common parent
(Public Library of Science, 2011)
Nested association mapping (NAM) is a novel genetic mating design that combines the advantages of linkage analysis and association mapping. This design provides opportunities to study the inheritance of complex traits, but ...
Quantitative trait locus mapping with background control in genetic populations of clonal F1 and double cross
In this study, we considered five categories of molecular markers in clonal F1 and double cross populations, based on the number of distinguishable alleles and the number of distinguishable genotypes at the marker locus. ...
Molecular mapping across three populations reveals a QTL hotspot region on chromosome 3 for secondary traits associated with drought tolerance in tropical maize
(Springer; Springer Nature, 2014)
Identifying quantitative trait loci (QTL) of sizeable effects that are expressed in diverse genetic backgrounds across contrasting water regimes particularly for secondary traits can significantly complement the conventional ...
Improving maize grain yield under drought stress and non-stress environments in Sub-Saharan Africa using marker-assisted recurrent selection
(Crop Science Society of America (CSSA), 2016)
In marker-assisted recurrent selection (MARS), a subset of molecular markers significantly associated with target traits of interest are used to predict the breeding value of individual plants, followed by rapid recombination ...
QTL mapping for adult-plant resistance to powdery mildew in bread wheat
(Institute of Crop Sciences, 2006)
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a major wheat disease in China. Use of adult-plant resistance is an effective method to develop wheat cultivars with durable resistance to powdery mildew. In ...
Towards molecular breeding of reproductive traits in cereal crops
(Wiley Open Access; Association of Applied Biologists; Society for Experimental Biology; Blackwell Publishing, 2008)
The transition from vegetative to reproductive phase, flowering per se, floral organ development, panicle structure and morphology, meiosis, pollination and fertilization, cytoplasmic male sterility (CMS) and fertility ...
Drought - inducible genes and differentially expressed sequence tags associated with components of drought tolerance in durum wheat
(Academic Journals, 2008)
Drought stress is one of the most important environmental factors reducing cereal yields. The genetic and physiological bases of drought tolerance in durum wheat was investigated by QTL mapping and by mapping candidate ...
Drought susceptibility of modern rice varieties: an effect of linkage of drought tolerance with undesirable traits
(Nature Publishing, 2015)
Green Revolution (GR) rice varieties are high yielding but typically drought sensitive. This is partly due to the tight linkage between the loci governing plant height and drought tolerance. This linkage is illustrated ...
Predicting hybrid performances for quality traits through genomic-assisted approaches in Central European wheat
(Public Library of Science, 2016)
Bread-making quality traits are central targets for wheat breeding. The objectives of our study were to (1) examine the presence of major effect QTLs for quality traits in a Central European elite wheat population, (2) ...
QTL Analysis and nested association mapping for adult plant resistance to Powdery Mildew in two bread wheat populations
CIMMYT wheat (Triticum aestivum L.) lines Francolin#1 and Quaiu#3 displayed effective and stable adult plant resistance (APR) to Chinese Blumeria graminis f. sp. tritici isolates in the field. To elucidate their genetic ...
