Gains in maize genetic improvement in Eastern and Southern Africa: I. CIMMYT hybrid breeding pipeline
(Crop Science Society of America (CSSA), 2017)
Monitoring of genetic gain in crop genetic improvement programs is necessary to measure the efficiency of the program. Periodic measurement of genetic gain also allows the efficiency of new technologies incorporated into ...
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 ...
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 ...
Seedling and slow rusting resistances to leaf rust in CIMMYT wheat lines
(Institute of Crop Sciences, 2011)
CIMMYT wheat has played an important role in wheat breeding in China. Identification of leaf rust resistance genes in CIMMYT wheat is important for developing wheat cultivars with resistance to leaf rust in China. A total ...
Determination of resistance against to Cereal cyst nematode, Heterodera avenae (Wollenweber, 1924) in some wheat germplasm
(Entomological Society Turkey, Ege University, 2013)
The cereal cyst nematode, Heterodera avenae is one of the most important pests of wheat in many countries in the world with different climatic types. Heterodera. avenae is commonly distributed in the Eastern Mediterranean ...
Enhanced resistance in wheat against stem rust achieved by marker assisted backcrossing involving three independent Sr genes
Marker assisted backcrossing (MABC) was used to transfer the three stem rust (Puccinia graminis tritici)resistant genes Sr25, SrWeb and Sr50 into the popular Indian wheat cv. HUW234. The donor was theCIMMYT breeding line ...
Genetic diversity of microsatellite alleles located at quantitative resistance loci for Ascochyta blight resistance in a global collection of chickpea germplasm
(Universitá Degli Studi Firenze, 2013)
A global collection of 43 chickpea (Cicer arietinum L.) genotypes, resistant and susceptible to Ascochyta blight caused by Ascochyta rabiei was evaluated for the disease under controlled conditions. In this study three ...
Specificity of a rust resistance suppressor on 7DL in the spring wheat cultivar Canthatch
(American Phytopathological Society (APS), 2015)
The spring wheat ‘Canthatch’ has been shown to suppress stem rust resistance genes in the background due to the presence of a suppressor gene located on the long arm of chromosome 7D. However, it is unclear whether the ...
Harnessing diversity in wheat to enhance grain yield, climate resilience, disease and insect pest resistance and nutrition through conventional and modern breeding approaches
Current trends in population growth and consumption patterns continue to increase the demand for wheat, a key cereal for global food security. Further, multiple abiotic challenges due to climate change and evolving pathogen ...
Relative performance of testers to identify elite lines of corn (Zea mays L.)
(Consiglio per la Ricerca e la sperimentazione in Agricoltura, Unità di Ricerca per la Maiscoltura, 1998)
Testcross evaluation is used to determine the relative potential of corn (Zea mays L.) lines in a hybrid breeding program. Choice of tester is important for efficient selection among lines for their potential in hybrids. ...
