Genetics of resistance to yellow rust in PBW343 × Kenya Kudu recombinant inbred line population and mapping of a new resistance gene YrKK
Yellow or stripe rust, caused by Puccinia striiformis f. sp. tritici, is an important disease of common wheat (Triticum aestivum L.) worldwide. A recombinant inbred line (RIL) population, derived from the cross PBW343 × ...
Relationship between the number of partial resistance genes and the response to leaf rust in wheat genotypes
(SciELO; Instituto de Investigaciones Agropecuarias,INIA, 2018)
The adult plant resistance conferred by genes with an additive effect is an alternative to achieve durable resistance to leaf rust caused by the fungus Puccinia triticina in wheat (Triticum spp.) The objective of this study ...
Genetic gains for grain yield in CIMMYT’s semi-arid wheat yield trials grown in suboptimal environments
(Crop Science, 2018)
Wheat (Triticum aestivum L.) is a major staple food crop grown worldwide on >220 million ha. Climate change is regarded to have severe effect on wheat yields, and unpredictable drought stress is one of the most important ...
Identification and validation of a common stem rust resistance locus in two bi-parental populations
(Frontiers; Frontiers Media, 2018)
Races belonging to Ug99 lineage of stem rust fungus Puccinia graminis f. sp. tritici (Pgt) continue to pose a threat to wheat (Triticum aestivum L.) production in various African countries. Growing resistant varieties is ...
Association mapping and gene-gene interaction for stem rust resistance in CIMMYT spring wheat germplasm
The recent emergence of wheat stem rust Ug99 and evolution of new races within the lineage threatens global wheat production because they overcome widely deployed stem rust resistance (Sr) genes that had been effective for ...
Genetics of greenbug resistance in synthetic hexaploid wheat derived germplasm
The greenbug, Schizaphis graminum Rondani, significantly reduces wheat, Triticum aestivum L., grain yields if not controlled. Host plant resistance (HPR) can protect yield, is environmentally friendly and easy to use. Our ...
