Genetic diversity of the mating type and toxin production genes in Pyrenophora tritici-repentis
(American Phytopathological Society (APS), 2010)
Pyrenophora tritici-repentis, the causal agent of tan spot on wheat, is a homothallic loculoascomycete with a complex race structure. The objectives of this study were to confirm the homothallic nature of the pathogen, ...
The Gametophyte-1 locus and reproductive isolation among Zea mays subspecies
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 2006)
Fourteen paired populations of annual teosinte and an associated maize landrace were characterized for allelic composition of the potential crossing barrier locus ga1. The four populations of subspecies parviglumis teosinte ...
Molecular marker mapping of Leaf Rust resistance gene Lr46 and its association with Strip Rust resistance gene Yr29 in wheat
(American Phytopathological Society (APS), 2003)
Leaf and stripe rusts, caused by Puccinia triticina and P. striiformis, respectively, are globally important fungal diseases of wheat that cause significant annual yield losses. A gene that confers slow rusting resistance ...
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 ...
Seedling and slow rusting resistances to leaf rust in CIMMYT wheat lines
(Institute of Crop Sciences, 2011)
CIMMYT wheat has played an important role in wheat breeding in China. Identification of leaf rust resistance genes in CIMMYT wheat is important for developing wheat cultivars with resistance to leaf rust in China. A total ...
Genetica de la resistencia a roya amarilla en plantas adultas de trigo harinero
(Sociedad Mexicana de Fitogenética, 2009)
La roya lineal amarilla del trigo (Triticum aestivum L.) causada por Puccinia striiformis f. sp. tritici es una enfermedad de creciente importancia en los Valles Altos de México, pues llega a causar perdidas en el rendimiento ...
The mixed inheritance analysis of polyphenol oxidase activities in winter wheat
(Institute of Crop Sciences, 2004)
Inheritance of PPO activity in 71 DH lines from the cross of ZhongYou 9507×CA9632 was investigated by the mixed major gene plus poly-gene inheritance model of quantitative traits. The results showed that PPO activity in ...
Identification and molecular characterization of leaf rust resistance gene Lr14a in durum wheat
(American Phytopathological Society (APS), 2008)
Leaf rust, caused by Puccinia triticina, is an important disease of durum wheat (Triticum turgidum subsp. durum) and only a few designated resistance genes are known to occur in this crop. A dominant leaf rust resistance ...
Validation of the effects of molecular marker polymorphisms in LcyE and CrtRB1 on provitamin A concentrations for 26 tropical maize populations
Vitamin A deficiency (VAD) compromises immune function and is the leading cause of preventable blindness in children in many developing countries. Biofortification, or breeding staple food crops that are rich in micronutrients, ...
Characterization of novel LMW-GS genes at Glu-D3 locus on chromosome 1D in Aegilops tauschii
(BioMed Central, 2008)
The objectives of this study were to clarify the relationship between LMW-GS Glu-D3 gene of Ae. tauschii registered in GenBank and the six Glu-D3 genes including 12 allelic variants of common wheat characterized in our ...
