QTL mapping of adult-plant resistance to leaf rust in the wheat cross Zhou 8425B/Chinese spring using high-density SNP markers
Wheat leaf rust is an important disease worldwide. Growing resistant cultivars is an effective means to control the disease. In the present study, 244 recombinant inbred lines from Zhou 8425B/Chinese Spring cross were ...
Molecular mapping of a non-host resistance gene YrpstY1 in barley (Hordeum vulgare L.) for resistance to wheat stripe rust
Cultivated barley ( Hordeum vulgare L.) is considered as a non-host or inappropriate host species for wheat stripe rust caused by Puccinia striiformis f. sp. tritici . Most barley cultivars show a broad-spectrum resistance ...
Genome-wide association mapping of black point reaction in common wheat (Triticum aestivum L.)
(BioMed Central, 2017)
Black point is a serious threat to wheat production and can be managed by host resistance. Marker-assisted selection (MAS) has the potential to accelerate genetic improvement of black point resistance in wheat breeding. ...
Update on wheat improvement activities in China
(Chinese Academy of Agricultural Science; CIMMYT, 2017)
Strategic crossing of biomass and harvest index—source and sink—achieves genetic gains in wheat
To accelerate genetic gains in breeding, physiological trait (PT) characterization of candidate parents can help make more strategic crosses, increasing the probability of accumulating favorable alleles compared to crossing ...
Genome-wide association mapping of vitamins B1 and B2 in common wheat
Vitamin B is essential for maintaining normal life activities in humans and animals who have to intake the microelement from the outside, especially from cereal products. In the present study 166 Chinese and foreign wheat ...
Genotypic variation in wheat flour lysophospholipids
Lysophospholipids (LPLs) are the most abundant polar lipids in wheat endosperm and naturally complex with amylose, affecting starch physicochemical properties. We analyzed LPLs in wheat flour from 58 cultivars which differ ...
Fast-forwarding genetic gain
Speed breeding’ enables scientists to exploit gene bank accessions and mutant collections for an unparalleled rapid gene discovery and gene deployment. Combining speed breeding and other leading-edge plant breeding ...
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 ...
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 ...
