Biotechnology applications for wheat improvement at CIMMYT
(The Scientific and Technology Research Council of Turkey, 2005)
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 ...
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. ...
More on the introduction of temperate maize into Europe: large-scale bulk SSR genotyping and new historical elements
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2006)
The commonly accepted scenario for the spread of maize into Europe is a single introduction followed by a slow adaptation to temperate climates. With the purpose of clarifying the origins and modalities of maize introduction ...
Molecular characterization of tropical maize inbred lines using microsatellite DNA markers
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2014)
An insight on diversity and relationships among germplasm is important in any breeding program for crop improvement. The main objectives of our study were to: (i) determine the level of genetic diversity within mid altitude ...
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 ...
Characterization of Xinjiang local and intoduced wheat germplasm for high molecular weight glutenin subunits and quality-related genes with molecular markers
(Institute of Crop Sciences, 2009)
High molecular weight glutenin subunits (HMW-GS), 1B·1R translocation, polyphenol oxidase (PPO) activities, and yellow pigment content are mostly correlated with the processing quality of common wheat (Triticum aestivum ...
Utilization of 1BL/1RS translocation in wheat breeding in China
(Institute of Crop Sciences, 2004)
In total , 179 predominant cultivars in recent 30 years and new breeder’s lines from main ecological zones of China were examined by SDS2PAGE and SCAR for the presence of 1BL/ 1RS. On average , 38 % of Chinese wheats ...
Characterization of mandarin (Citrus spp.) using morphological and AFLP markers
Sixty-three mandarin (Citrus spp.) cultivars from the collection of the Campo Citrícola Experimental Francisco Villa, Tamaulipas, Mexico, were evaluated using morphological and Amplified Fragment Length Polymorphism (AFLP) ...
Mapping QTLs for polyphenol oxidase activity in a DH population from common wheat
(Institute of Crop Sciences, 2005)
The polyphenol oxidase ( PPO) activity is a major factor to cause an undesirable brown discoloration of wheat based end products during processing or storage. A double haploid (DH) population with 71 lines derived from ...
