Report
Wheat, barley, and triticale cultivars: a list of publications in which national cereal breeders have noted the cooperation or germplasm they received from CIMMYT
(CIMMYT, 1997)
Sustainable cereal production on farmers' fields: that is the ultimate measure of the impact of CIMMYT's research. Its achievement requires a combination of effective technologies and the most appropriate seeds. Over the ...
Report
Adaptation of wheat to the canopy environment: physiological evidence that selection for vigor or random selection may reduce the frequency of high-yielding genotypes
(CIMMYT, 1993)
Increasing the potential yield of wheat is a major thrust of CIMMYT's Wheat Program. Farmer's wheat yields are linearly related to the yield potential of new varieties. At the same time, breeders should ideally be able to ...
Research Report
Intercropping cereals with N-fixing legume species: a method for conserving soil resources in low-input systems
(CIMMYT, 1993)
The natural resources of the developing world are becoming increasingly threatened as the agricultural sector intensifies. A major resource being lost is the topsoil. Low levels of soil organic matter and the incomplete ...
Report
Vernalization requirement and response to day length in guiding development in wheat
(CIMMYT, 1993)
Vernalization requirement and response to day length are the major factors controlling development in wheat (Triticum aesitvum L.). This study was to determine how they integrate in the field in Obregon, Sonora, Mexico to ...
Report
Increasing the yield potential of irrigated bread wheat: basis for physiological research at CIMMYT
(CIMMYT, 1992)
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 ...
Report
Canopy temperatures of wheat: relationships with yield and potential as a technique for early generation selection
(CIMMYT, 1993)
It is shown that, for bread wheat, air-canopy temperature difference correlates significantly with grain yield, especially when measurements are taken later in the day, We discuss the potential of this technique as an early ...
Handbook
Guide to plant and crop sampling: measurements and observations for agronomic and physiological research in small grain cereals
(CIMMYT, 1994)
This wheat special report is a guide that outlines the procedures used for measuring many components of the crop in small grains research. The actual observations taken, however, will depend on the objectives of the work ...
Report
Genetic diversity for photosynthesis in wheat under heat-stressed environments and its relationship to productivity
(CIMMYT, 1994)
Genetic variation in photosynthetic rate, stomatal conductance, leaf chlorophyll content, and dark respiration was studied in 16 wheat genotypes (Triticum aestivum L.) grown under high-temperature field conditions in central ...
Report
Assessment and development of an agricultural research station: physical and personnel needs
(CIMMYT, 1994)
The agricultural research station plays a vital role in the generation of both new knowledge and appropriate technologies for farmers. However, despite the importance and complexity of running research stations, there is ...
Report
Using canopy temperature depression to select for yield potential of wheat in heat stressed environments
(CIMMYT, 1997)
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 ...
