Improved genetic, genomic and statistical technologies have increased the capacity to
enrich breeding populations for key alleles underpinning adaptation and continued genetic …

Genetic diversity is paramount for cultivated crops genetic improvement, and for wheat this
resides in three gene pools of the Triticeae. In wheat, access to this diversity and its …

Race-specific resistance genes protect the global wheat crop from stem rust disease caused
by Puccinia graminis f. sp. tritici (Pgt) but are often overcome owing to evolution of new …

Key message This consensus map of stem rust genes, QTLs, and molecular markers will
facilitate the identification of new resistance genes and provide a resource of in formation for …

Chromosome engineering is a useful strategy for transfer of alien genes from wild relatives
into modern crops. However, this strategy has not been extensively used for alien gene …

The use of major resistance genes is a cost-effective strategy for preventing stem rust
epidemics in wheat crops. The stem rust resistance gene Sr39 provides resistance to all …

North American durum lines, selected for resistance to TTKSK (Ug99) and related races of
Puccinia graminis f. sp. tritici in Kenya, became susceptible in Debre Zeit, Ethiopia …

This study reports the discovery and molecular mapping of a resistance gene effective
against stem rust races RKQQC and TTKSK (Ug99) derived from Aegilops geniculata (2 n …

Key message Wheat lines carrying Ug99-effective stem rust resistance gene Sr43 on
shortened alien chromosome segments were produced using chromosome engineering …

Rye is one of the most commonly used sources of elite genes in wheat improvement
programs. Due to the high collinearity of the genomes of both cereal species, it is possible to …
