Identification of Fusarium Head Blight Resistance in Triticum timopheevii Accessions and Characterization of Wheat-T. timopheevii Introgression Lines for Enhanced Resistance [PDF]

Frontiers in Plant Science, 2022
A diverse panel of wheat wild relative species was screened for resistance to Fusarium head blight (FHB) by spray inoculation. The great majority of species and accessions were susceptible or highly susceptible to FHB. Accessions of Triticum timopheevii (

Prebreeding studies of leaf rust resistant Triticum aestivum/T. timopheevii line L624 [PDF]

Вавиловский журнал генетики и селекции, 2023
Triticum timopheevii Zhuk. attracts the attention of bread wheat breeders with its high immunity to the leaf rust pathogen. However, introgressions from this species in Triticum aestivum L. are little used in practical breeding.

GBS-based identification of Triticum timopheevii introgressions in a wheat pre-breeding population [PDF]

Frontiers in Plant Science
Triticum timopheevii (2n = 4x = 28, GGAtAt) is a valuable wild wheat relative for improving disease resistance and agronomic performance in bread wheat, although the detection of introgressed chromosomal segments remains challenging due to close genomic ...

Introgression of the Triticum timopheevii Genome Into Wheat Detected by Chromosome-Specific Kompetitive Allele Specific PCR Markers

Frontiers in Plant Science, 2022
Triticum timopheevii (2n = 28, AtAtGG) is a tetraploid wild relative species with great potential to increase the genetic diversity of hexaploid wheat Triticum aestivum (2n = 42, AABBDD) for various important agronomic traits.

Exploring the genetic variation of wheat-Triticum timopheevii introgression lines for flowering morphology traits for hybrid wheat use [PDF]

Frontiers in Plant Science
IntroductionThe autogamous nature of wheat presents a significant challenge for hybrid wheat breeding, which relies on cross-pollination. To facilitate hybrid wheat production, it is essential to modify the floral morphology of wheat to promote ...

Genetic resource optimization: a core collection of tetraploid wheat from 2,254 NBRP-wheat accessions [PDF]

BMC Plant Biology
Background Tetraploid wheat, comprising both Emmer wheat (Triticum turgidum, AABB genome) and Timopheevii wheat (T. timopheevii, AAGG genome), harbors rich genetic diversity that remains underutilized in modern breeding.

Exploring genetic diversity of wild and related tetraploid wheat species Triticum turgidum and Triticum timopheevii [PDF]

Journal of Advanced Research, 2023
Introduction: The domestication bottleneck has reduced genetic diversity in wheat, necessitating the use of wild relatives in breeding programs. Wild tetraploid wheat are widely used in the breeding programs but with morphological characters, it is ...

Chromosome-scale genome assembly of bread wheat’s wild relative Triticum timopheevii [PDF]

Scientific Data
Wheat (Triticum aestivum) is one of the most important food crops with an urgent need for increase in its production to feed the growing world. Triticum timopheevii (2n = 4x = 28) is an allotetraploid wheat wild relative species containing the At and G ...

High variation in the gluten composition and grain protein content among synthetic wheat lines. [PDF]

PLoS ONE
Wheat wild relatives are important sources for the genetic enhancement of cultivated wheat. Here, we evaluated the gluten composition, grain protein content, and several quality-related gluten indices across 47 synthetic wheat lines or amphiploids ...
