Identification of genomic associations for adult plant resistance in the background of popular South Asian wheat cultivar, PBW343
Rusts, a fungal disease as old as its host plant wheat, has caused havoc for over 8000 years. As the rust pathogens can evolve into new virulent races which quickly defeat the resistance that primarily rely on race ...
Evaluation of bread wheat for both seedling and adult plant resistance to stem rust
(Academic Journals, 2012)
Wheat is an important staple food crop in sub-Saharan Africa. However, the current wheat consumption of 900 000 tons in Kenya outweighs the wheat production of 350 000 tons given the high population growth and inflation. ...
Stem rust resistance in a geographically diverse collection of spring wheat lines collected from across Africa
Following the emergence of the Ug99 lineage of Puccinia graminis f. sp. tritici (Pgt) a collective international effort has been undertaken to identify new sources of wheat stem rust resistance effective against these ...
Genomic selection for quantitative adult plant stem rust resistance in wheat
(Crop Science Society of America, 2014)
Quantitative adult plant resistance (APR) to stem rust (Puccinia graminis f. sp. tritici) is an important breeding target in wheat (Triticum aestivum L.) and a potential target for genomic selection (GS). To evaluate the ...
Identification and validation of single nucleotide polymorphic markers linked to Ug99 stem rust resistance in spring wheat
(Public Library of Science, 2017)
Wheat stem rust (Puccinia graminis f. sp. tritici Eriks. and E. Henn.) is one of the most destructive diseases world-wide. Races belonging to Ug99 (or TTKSK) continue to cause crop losses in East Africa and threaten global ...
Natural variation in elicitation of defense-signaling associates to field resistance against the spot blotch disease in bread wheat (Triticum aestivum L.)
Spot blotch, caused by the hemibiotropic fungus Bipolaris sorokiniana, is amongst the most damaging diseases of wheat. Still, natural variation in expression of biochemical traits that determine field resistance to spot ...
Multi-trait and multi-environment QTL analyses for resistance to wheat diseases
(Public Library of Science, 2012)
Background: Stripe rust, leaf rust, tan spot, and Karnal bunt are economically significant diseases impacting wheat production. The objectives of this study were to identify quantitative trait loci for resistance to these ...
QTL mapping of adult-plant resistance to stripe rust in Chinese wheat cultivar Chuanyu 16
(Canadian Center of Science and Education, 2012)
Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a serious wheat fungal disease, causing significant annual yield losses worldwide. The Chinese wheat cultivar Chuanyu 16 has shown good adult-plant resistance ...
Effects of temperature stresses on the resistance of chickpea genotypes and aggressiveness of Didymella rabiei isolates
Chickpea (Cicer arietinum L.) is an important food and rotation crop in many parts of the world. Cold (freezing and chilling temperatures) and Ascochyta blight (Didymella rabiei) are the major constraints in chickpea ...
Resistencia parcial y específica a roya del tallo en la línea avanzada de trigo harinero ‘Kijil’
(Sociedad Mexicana de Fitogenética, 2019)
El hongo Puccina graminis f. sp. tritici es el agente causal de la roya del tallo del trigo (Triticum aestivum), éste puede causar pérdidas del rendimiento hasta de 40 % en variedades susceptibles, además puede mutar y ...
