Mapping and pyramiding of qualitative and quantitative resistance to stripe rust in barley
The identification and location of sources of genetic resistance to plant diseases are important contributions to the development of resistant varieties. The combination of different sources and types of resistance in the ...
QTL mapping in three tropical maize populations reveals a set of constitutive and adaptive genomic regions for drought tolerance
Despite numerous published reports of quantitative trait loci (QTL) for drought-related traits, practical applications of such QTL in maize improvement are scarce. Identifying QTL of sizeable effects that express more or ...
Validation of consensus quantitative trait loci associated with resistance to multiple foliar pathogens of maize
(American Phytopathological Society (APS), 2009)
Maize production in sub-Saharan Africa incurs serious losses to epiphytotics of foliar diseases. Quantitative trait loci conditioning partial resistance (rQTL) to infection by causal agents of gray leaf spot (GLS), northern ...
QTL mapping for resistance to SCMV in chinese maize germplasm
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2003)
In this report we identified QTLs conferring resistance to Sugarcane Mosaic Virus (SCMV) and their use in marker-assisted selection (MAS) was described. The genetic linkage map covering 1543 cM on ten chromosomes with an ...
QTLs asociados al contenido de carotenos en hojas de maiz (Zea mays L.)
(Colegio de Postgraduados, 2012)
Los carotenos son pigmentos antioxidantes que captan foto¬nes del espectro de luz visible y protegen a los tejidos de las plantas contra la foto-oxidación, lo cual está relacionado con la tasa fotosintética y rendimiento ...
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 ...
Identification and mapping of leaf, stem and stripe rust resistance quantitative trait loci and their interactions in durum wheat
(Springer Verlag, 2012)
Leaf rust (Puccinia triticina Eriks.), stripe rust (Puccinia striiformis f. tritici Eriks.) and stem rust (Puccinia graminis f. sp. tritici) cause major production losses in durum wheat (Triticum turgidum L. var. durum). ...
Mapping QTLs for polyphenol oxidase activity in a DH population from common wheat
(Institute of Crop Sciences, 2005)
The polyphenol oxidase ( PPO) activity is a major factor to cause an undesirable brown discoloration of wheat based end products during processing or storage. A double haploid (DH) population with 71 lines derived from ...
Analysis and answers to frequently asked questions in quantitative trait locus mapping
(Institute of Crop Sciences, 2010)
QTL mapping is an important step in gene fine mapping, map-based cloning, and the efficient use of gene information in molecular breeding. Questions are frequently met and asked in the application of QTL mapping in practical ...
Quantitative trait loci mapping for adult-plant resistance to powdery mildew in bread wheat
(American Phytopathological Society (APS), 2006)
Powdery mildew, caused by Blumeria graminis f. sp. tritici, is a major disease to wheat (Triticum aestivum) worldwide. Use of adult-plant resistance (APR) is an effective method to develop wheat cultivars with durable ...
