Investigación sobre políticas para el desarrollo sostenible en las laderas mesoamericanas
(IICA; IFPRI; CIMMYT, 1997)
En los últimos años ha surgido un fuerte interés por parte de los investigadores de Centro América y México, por la investigación sobre políticas para el desarrollo sostenible y el manejo de los recursos naturales (MRN) ...
Guidelines for Dry Seeded Rice (DSR): in the Terai and Mid Hills of Nepal
(CSISA; IFAD; IRRI; CIMMYT, 1999)
Dry seeded rice (DSR) is becoming an attractive option for farmers as it has a much lower labor requirement and establishment cost than manually transplanted rice. Labor for transplanting rice has become scarce and costly ...
Increasing yield potential in wheat: breaking the barriers. Proceedings of a workshop held in Ciudad Obregon, Sonora, Mexico
CIMMYT's focus on developing wheat varieties that produce higher and more stable yields has made a tremendous difference in the lives of millions of people in the developing world. In the mid 1960s, the dramatic increases ...
1990-91 CIMMYT World wheat facts and trends: wheat and barley production in rainfed marginal environments of the developing world
A synopsis of recent trends in rainfed marginal environments of the developing world is followed by a description of the major wheat and barley farming systems in West Asia-North Africa (WANA) and South Asia (the role of ...
Results of the 1st International Heat Stress Genotype Experiment
Fischer (1989) summarized the detrimental effects of high temperature on wheat growth as follows: Yield reduction can occur at temperatures above a mean as low as 150C, with the spike and grain growth phases being especially ...
Increasing the yield potential of irrigated bread wheat: basis for physiological research at CIMMYT
Yield potential (YP) is defined as the "yield of a cultivar grown in environments to which it is adapted when nutrients and water are nonlimiting, and when pests, diseases, weeds, lodging, and other stresses are effectively ...
Using canopy temperature depression to select for yield potential of wheat in heat stressed environments
The main objective of the study was to validate the use of canopy temperature depression (CTD) as a rapid early generation screening tool for heat tolerance in wheat. CTD was measured at hot sites in Mexico on F2 derived ...
Photosynthetic characteristics of synthetic bread wheats
In the process of genetic improvement of bread wheat, photosynthetic rate per unit leaf area has decreased significantly from the maximum photosynthetic rate (Pmax) of the crop's diploid ancestors (donors of the A, B, and ...
CIMMYT World wheat facts and trends: supplement 1995 ongoing research at CIMMYT: understanding wheat genetic diversity and international flows of genetic resources
This supplement to the CIMJvfYT World Wheat Facts and Trends series summarizes objectives and preliminary results of a study of wheat genetic diversity and international flows of genetic resources (final results will appear ...
