Update on wheat improvement activities in China
(Chinese Academy of Agricultural Science; CIMMYT, 2017)
Wheat genetic resources enhancement by the International Maize and Wheat Improvement Center (CIMMYT)
The International Maize and Wheat Improvement Center (CIMMYT) acts as a catalyst and leader in a global maize and wheat innovation network that serves the poor in the developing world. Drawing on strong science and effective ...
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 ...
Segregation analysis indicates that Puroindoline b-2 variants 2 and 3 are allelic in Triticum aestivum and that a revision to Puroindoline b-2 gene symbolization is indicated
Genetic and kernel texture relationships between Puroindoline b-2 variants 2 and 3 have not been fully established in wheat (Triticum aestivum L.). Here, 480 F2 plants, derived from three hard spring wheat populations were ...
Characterization of dense and erect panicle 1 gene (tadep1) located on common wheat group 5 chromosomes and development of allele-specific markers
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 ...
Fine mapping of leaf rust resistance Genelrzh84 using expressed sequence tag and sequence-tagged site markers, and Allelism with other genes on wheat chromosome 1B
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 ...
Characterization of Chinese wheat germplasm for resistance to Fusarium head blight at CIMMYT, Mexico
Fusarium head blight (FHB) poses a challenge for wheat breeders worldwide; there are limited sources of resistance and the genetic basis for resistance is not well understood. In the mid-1980s, a shuttle breeding and ...
Molecular mapping of leaf rust resistance gene LrNJ97 in Chinese wheat line Neijiang 977671
Neijiang 977671 and 19 near-isogenic lines with known leaf rust resistance genes were inoculated with 12 pathotypes of Puccinia triticina for postulation of leaf rust resistance genes effective at the seedling stage. The ...
Evaluation of molecular markers specific for 1BL-1RS translocation and characterization of 1RS chromosome in wheat varieties from different origins
For the purpose of discriminating the 1BL-1RS translocation for wheat quality improvement, a total of ten STS, one SCAR and four RAPD markers specific to 1BL-1RS translocations as well as 22 SSR markers located on 1RS were ...
