Genome-wide association study reveals novel genomic regions for grain yield and yield-related traits in drought-stressed synthetic hexaploid wheat
Synthetic hexaploid wheat (SHW; 2n = 6x = 42, AABBDD, Triticum aestivum L.) is produced from an interspecific cross between durum wheat (2n = 4x = 28, AABB, T. turgidum L.) and goat grass (2n = 2x = 14, DD, Aegilops tauschii ...
Rubisco catalytic properties of wild and domesticated relatives provide scope for improving wheat photosynthesis
(Oxford University Press, 2016)
Rubisco is a major target for improving crop photosynthesis and yield, yet natural diversity in catalytic properties of this enzyme is poorly understood. Rubisco from 25 genotypes of the Triticeae tribe, including wild ...
Photosynthetic contribution of the ear to grain filling in wheat : a comparison of different methodologies for evaluation
(Oxford University Press; Society for Experimental Biology, 2016)
The culm (particularly the flag leaf) and the ear are believed to play a major role in providing assimilates for grain filling in wheat. However, the results obtained in the past varied depending on the methodology applied. ...
Lodging resistance and yield potential of winter wheat: effect of planting density and genotype
(Higher Education Press, 2015)
Improved lodging resistance is important for achieving high yield in irrigated environments. This study was conducted to determine genotypic variation in lodging resistance and related morphological traits among ...
Mapping smallholder wheat yields and sowing dates using micro-satellite data
Remote sensing offers a low-cost method for developing spatially continuous crop production statistics across large areas and through time. Nevertheless, it has been difficult to characterize the production of individual ...
QTL characterization of fusarium head blight resistance in CIMMYT bread wheat line soru#1
(Public Library of Science, 2016)
Fusarium head blight (FHB) resistant line Soru#1 was hybridized with the German cultivar Naxos to generate 131 recombinant inbred lines for QTL mapping. The population was phenotyped for FHB and associated traits in spray ...
Dwarfing genes Rht-B1b and Rht-D1b are associated with both type I FHB susceptibility and low anther extrusion in two bread wheat populations
(Public Library of Science, 2016)
It has been well documented that dwarfing genes Rht-B1b and Rht-D1b are associated with Type I susceptibility to Fusarium head blight (FHB) in wheat; but the underlying mechanism has not been well delineated. Anther extrusion ...
Mining centuries old In situ conserved turkish wheat landraces for grain yield and stripe rust resistance genes
(Frontiers Media, 2016)
Wheat landraces in Turkey are an important genetic resource for wheat improvement. An exhaustive 5-year (2009–2014) effort made by the International Winter Wheat Improvement Programme (IWWIP), a cooperative program between ...
Hyperspectral reflectance as a tool to measure biochemical and physiological traits in wheat
(Society for Experimental Biology, 2017)
Improving photosynthesis to raise wheat yield potential has emerged as a major target for wheat physiologists. Photosynthesis-related traits, such as nitrogen per unit leaf area (Narea) and leaf dry mass per area (LMA), ...
QTL mapping of adult-plant resistance to leaf rust in the wheat cross Zhou 8425B/Chinese spring using high-density SNP markers
(Frontiers Media, 2017)
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 ...
