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 ...

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 ...

QTL Analysis and nested association mapping for adult plant resistance to Powdery Mildew in two bread wheat populations
(Frontiers, 2017)
CIMMYT wheat (Triticum aestivum L.) lines Francolin#1 and Quaiu#3 displayed effective and stable adult plant resistance (APR) to Chinese Blumeria graminis f. sp. tritici isolates in the field. To elucidate their genetic ...

Molecular mapping of powdery mildew resistance gene in wheat cultivar Jimai 22
(Institute of Crop Sciences, 2009)
Wheat powdery mildew, caused by Blumeria graminis f. sp. tritici, is one of the most important diseases of wheat (Triticum aestivum L.) worldwide. Breeding resistant wheat cultivars is the most economical and effective ...

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. ...

QTL Mapping of Fusarium moniliforme ear rot resistance in highland maize, Mexico
(Colegio de Postgraduados, 2001)
La pudrición de la mazorca causada por Fusarium moniliforme ocasiona cuantiosas pérdidas en maíces (Zea mays L.) adaptados a los valles altos de México. Los objetivos de este trabajo fueron identificar loci para un carácter ...
Article
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 ...
Article
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 ...
Article
The genetic dissection of quantitative traits in crops
(Pontificia Universidad Católica de Valparaíso, 2010)
Most traits of interest in plant breeding show quantitative inheritance, which complicate the breeding process since phenotypic performances only partially reflects the genetic values of individuals. The genetic variation ...
Article
Hybrid wheat prediction using genomic, pedigree, and environmental covariables interaction models
(Crop Science Society of America, 2019)
In this study, we used genotype × environment interactions (G×E) models for hybrid prediction, where similarity between lines was assessed by pedigree and molecular markers, and similarity between environments was accounted ...
