The increasing role of wheat consumption and imports in the developing world
This study presents in detail the themes explored in the CIMMYT publication, World Wheat Facts and Trends, Report 2 (1983). It looks at changes in wheat consumption in developing countries, examines the increasing importance ...
Optimal search in ex situ collections of wheat genetic resources
This paper develops a theoretical model for analyzing gene bank management decisions regarding the search for traits of economic value in ex situ collections of wheat. The model is applied to data on the probability of ...
Impacts of international wheat breeding research in the developing world, 1966-90
1986-90. Overall, varieties originating directly from CIMMYT crosses or from NARS crosses using a CIMMYT parent occupy 40 million hectares of wheat in the developing world. It is estimated that adoption of MVs from 1977 ...
Impacts of international wheat breeding research in developing countries, 1966-97
This report, which updates and extends the findings of an earlier CIMMYT study published in 1993, examines the impacts of international wheat breeding research in the developing world. Covering the period 1966-97, the ...
Nutrient deficiencies and toxicities in wheat: a guide for field identification
The use of visual symptoms to identify nutrient deficiencies and toxicities in plants can be improved by both their careful observation and description. This guide attempts to accurately describe symptoms of nutrient ...
Bunt and smut diseases of wheat: concepts and methods of disease management
Five bunt and smut diseases are regularly associated with wheat ( Triticum spp.). These are: common bunt (Tilletia spp.), dwarf bunt (T. controversa), Karnal bunt (T. indica), loose smut (Ustilago tritici), and flag smut ...
Planning technologies appropriate to farmers: concepts and procedures
We have prepared this Manual for professionals involved in research on improving agricultural technology for farmers. We believe that it will be useful to both biological scientists and social scientists and that parts of ...
The bacterial diseases of wheat: concepts and methods of disease management
The most common bacterial pathogens that attack wheat are grouped under the names Xanthomonas translucens and Pseudomonas syringae. Pathovars (bacterial strains pathogenic to a specific host or hosts) included in X. ...
Economic criteria for establishing plant breeding programs
A general model of annual costs and lagged annual returns from a plant breeding program is developed to estimate the threshold sizes of a crop industry at which different breeding programs could be economically justified, ...
Applications of raised-bed planting systems to wheat
Wheat has traditionally been planted in solid stands, especially in irrigated environments and rainfed production systems with moderate to high rainfall. Wheat is usually planted by either drilling closely spaced rows 10-30 ...
