Fine mapping of leaf rust resistance gene LrZH84 using expressed sequence tag and sequence-tagged site markers, and allelism with other genes on wheat chromosome 1B
(American Phytopathological Society (APS), 2013)
Zhou 8425B, possessing the leaf rust resistance gene LrZH84, is an elite wheat (Triticum aestivum) parental line in the Yellow-Huai Valley region of China. In the present study, 2,086 F2 plants derived from Zhou 8425B/Chinese ...

Breeding value of primary synthetic wheat genotypes for grain yield
(Public Library of Science, 2016)
To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) ...

Harnessing genetic potential of wheat germplasm banks through impact-oriented-prebreeding for future food and nutritional security
(Nature Publishing Group, 2018)
The value of exotic wheat genetic resources for accelerating grain yield gains is largely unproven and unrealized. We used next-generation sequencing, together with multi-environment phenotyping, to study the contribution ...

Genome-wide association mapping for leaf tip necrosis and pseudo-black chaff in relation to durable rust resistance in wheat
(Crop Science Society of America, 2015)
The partial rust resistance genes Lr34 and Sr2 have been used extensively in wheat (Triticum aestivum L.) improvement, as they confer exceptional durability. Interestingly, the resistance of Lr34 is associated with the ...

Genetic dissection of grain zinc concentration in spring wheat for mainstreaming biofortification in CIMMYT wheat breeding
(Nature Publishing Group, 2018)
Wheat is an important staple that acts as a primary source of dietary energy, protein, and essential micronutrients such as iron (Fe) and zinc (Zn) for the world?s population. Approximately two billion people suffer from ...

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 ...

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 ...

Distribution of allelic variation for genes of vernalization and photoperiod among wheat cultivars from 23 countries
(Institute of Crop Sciences, 2011)
Molecular markers for vernalization genes Vrn-A1, Vrn-B1, Vrn-D1 and Vrn-B3 and photoperiod gene Ppd-D1 were used to detect the presence of these genes among 755 cultivars from 23 countries. Days to heading and physiological ...
