Yield potential progress in short bread wheats in Northwest Mexico
Germplasm from the spring wheat (Triticum aestivum L.) breeding program at the International Center for Improvement of Maize and Wheat (CIMMYT) has had a major impact on the yield of irrigated spring wheats in most developing ...
Genetic progress in wheat yield and nitrogen use efficiency under four nitrogen rates
The adaptation and performance of CIMMYT's bread wheat germplasm (Triticum aestivum L.) under conditions of low N fertility have been questioned because they were developed under medium-high levels of N fertility. The ...
Pre-harvest sprouting tolerance of wheat in the field and under rain simulation
Segregating and fixed lines, selected under controlled conditions in the rain simulator at the Plant Breeding Institute (PBI), were evaluated and selected further in the field at the International Maize and Wheat Improvement ...
Agronomic effects from chromosome translocations 7DL.7Ag and 1BL.1RS in spring wheat
In hexaploid wheat (Triticum aestivum L.) disease resistance genes transferred hom alien sources are often associated,vith undesirable traits. Replicated trials using near-isogenic lines of spring wheat 'Seri 82' were ...
Estimating the economic impact of breeding nonspecific resistance to leaf rust in modern bread wheat
Breeding for resistance to rust diseases in wheat is an example of productivity maintenance research. Productivity maintenance research is necessary to avoid contractions in the wheat supply curve that result from changes ...
CIMMYT's approach to breeding for wide adaptation
The wheat area in developing countries, including China, is around 100 million ha. To address the needs of these very diverse wheat growing areas, CIMMYT has defined 12 wheat mega-environments (ME). A ME is defined as ...
