The International Maize and Wheat Improvement Center (known – even in English – by its Spanish acronym CIMMYT for Centro Internacional de Mejoramiento de Maíz y Trigo) is a non-profit research-for-development organization that develops improved varieties of wheat and maize with the aim of contributing to food security, and innovates agricultural practices to help boost production, prevent ...
The International Maize and Wheat Improvement Center (CIMMYT) operates a conventional breeding program to provide optimized strains. The program began in the 1980s. [ 54 ] Hybrid seeds are distributed in Africa by its Drought Tolerant Maize for Africa project.
It is the simplest, easiest and oldest method of selection where individual plants are selected based on their phenotypic performance, and bulk seed selection proved to be quite effective in maize improvement at the initial stages but its efficacy especially for improvement of yield, soon came under severe criticism that culminated in the ...
Quality Protein Maize (QPM) is a family of maize varieties. QPM grain contains nearly twice as much lysine and tryptophan, amino acids that are essential for humans and monogastric animals but are limiting amino acids in grains. QPM is a product of conventional plant breeding (i.e., it is not genetically modified) and an example of ...
Participatory plant breeding (PPB) is when farmers are involved in a crop improvement programme with opportunities to make decisions and contribute to the research process at different stages. [34] [35] [36] Participatory approaches to crop improvement can also be applied when plant biotechnologies are being used for crop improvement. [37]
Since the induction of the International Maize and Wheat Improvement Center triticale breeding programme in 1964, the improvement in realised grain yield has been remarkable. In 1968, at Ciudad Obregón, Sonora, in northwest Mexico, the highest yielding triticale line produced 2.4 t/ha. Today, CIMMYT has released high yielding spring triticale ...
Recent research breakthroughs in biotechnology have revived interest in targeted drought resistance breeding and use of new genomics tools to enhance crop water productivity. Marker-assisted breeding is revolutionising the improvement of temperate field crops and will have similar impacts on breeding of tropical crops.
As part of its decentralization, ICARDA has established integrated research platforms that address research priorities in each region, but serve dry areas globally through collaboration and partnerships with national programs, advanced research institutions, and other partners in the development and dissemination of international public goods.
