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 ...
Molecular mapping of reduced plant height gene Rht24 in bread wheat
Height is an important trait related to plant architecture and yield potential in bread wheat (Triticum aestivum L.). We previously identified a major quantitative trait locus QPH.caas-6A flanked by simple sequence repeat ...
QTL Mapping of Fusarium moniliforme ear rot resistance in highland maize, Mexico
(Colegio de Postgraduados, 2001)
La pudrición de la mazorca causada por Fusarium moniliforme ocasiona cuantiosas pérdidas en maíces (Zea mays L.) adaptados a los valles altos de México. Los objetivos de este trabajo fueron identificar loci para un carácter ...
Mapping of wheat stripe rust resistance gene YrZH84 with RGAP markers and its application
(Institute of Crop Sciences, 2009)
Zhou 8425B, with an effective stripe rust resistance gene YrZH84, is a hall-mark parent line of wheat (Triticum aestivum L.) in the Yellow-Huai Rivers wheat growing region. An F2 population derived from the cross Zhou ...
Characterization of Overexpressed Bx7 gene (Bx7OE) in Chinese and CIMMYT wheats by STS markers
(Institute of Crop Sciences, 2009)
Over-expression of the high molecular weight glutenin subunit (HMW-GS) Bx7 is highly associated with dough strength of wheat (Triticum aestivum L.) flour. A total of 163 Chinese and CIMMYT wheat cultivars and advanced lines ...
Sampling strategies for conserving maize diversity when forming core subsets using genetic markers
(Crop Science Society of America (CSSA), 2006)
Core subsets can be formed on the basis of molecular markers and different sampling strategies. This research used genetic markers on three maize data sets for studying 24 stratified sampling strategies to investigate which ...
Wheat germplasm screening for stem rust resistance using conventional and molecular techniques
(Czech Academy of Agricultural Sciences, 2011)
In Central Asia, stem rust (Puccinia graminis f.sp. tritici) causes considerable damage, especially during growing seasons with high rainfall. Ug99 is a race of stem rust that is virulent to the majority of wheat varieties. ...
Characterization of dense and erect panicle 1 gene (tadep1) located on common wheat group 5 chromosomes and development of allele-specific markers
(Institute of Crop Sciences, 2013)
Dense and erect panicle 1 (OsDep1) gene is an important QTL controlling yield associated traits such as panicle length, erect type, and grain density in rice. In the present study, full-length genomic DNA sequences of ...
Crop breeding chips and genotyping platforms: progress, challenges, and perspectives
There is a rapidly rising trend in the development and application of molecular marker assays for gene mapping and discovery in field crops and trees. Thus far, more than 50 SNP arrays and 15 different types of ...
Progress of wheat breeding in China and the future perspective
(Institute of Crop Sciences, 2011)
During the last ten years, Chinese wheat breeding has mainly made progresses in three aspects, i.e., (1) two sets of cultivars with high yielding potential, improved quality, and multi-resistance to various diseases were ...
