Genetic Resources and Crop Evolution, 2007
The effective utilisation of available genetic resources of related species is essential for successful crops breeding and maintaining genetic variability within crops. Bread wheat, the basic cultivated wheat species, is an amphiploid (2n = 6x = 42) and, therefore, the production of new synthetic amphiploids using genomes of related species should ...

Structural chromosome differentiation between Triticum timopheevii and T. turgidum and T. aestivum
Theoretical and Applied Genetics, 1999Chromosome pairing at metaphase-I was analyzed in F1 hybrids among T. turgidum (AABB), T. aestivum (AABBDD), and T. timopheevii (AtAtGG) to study the chromosome structure of T. timopheevii relative to durum (T. turgidum) and bread (T. aestivum) wheats. Individual chromosomes and their arms were identified by means of C-banding.

In order to determine the fragment size of Triticum timopheevii chromosome segments introduced into wheat background and physically map the Pm6 gene, a total of 72 primers (including SSR and STS primers) were used to analyze the eight introduced introgression lines containing Pm6 gene.

Introgressive lines resulting from crossing common wheat Triticum aestivum with the tetraploid T. timopheevii are characterized by effective resistance to leaf rust caused by Puccinia triticina Eriks. Molecular analysis using 350 specific simple sequence repeat (SSR) markers determined localization of the T. timopheevii genome in chromosomes 1A, 2A, 2B,

Wheat powdery mildew is an economically important disease in cool and humid environments. Powdery mildew causes yield losses as high as 48% through a reduction in tiller survival, kernels per head, and kernel size. Race-specific host resistance is the most consistent, environmentally friendly and, economical method of control.

A Triticum timopheevii-derived bread wheat line, Selection G12, was screened with 40 pathotypes of leaf rust pathogen, Puccinia triticina at seedling stage and with two most commonly prevalent pathotypes 77-5 and 104-2 at adult plant stage. Selection G12 showed resistance at both seedling and adult plant stages.

NAM is an important domestication gene and valuable to enhance grain protein contents (GPCs) of modern wheat cultivars. In the present study, 12 NAM-G1 genes in Triticum timopheevii Zhuk. (AAGG, 2n=4x=28) were cloned. These genes had the same length of 1546 bp including two introns and three exons, and encoded a polypeptide of 407 amino acid residues ...
