Results of the 1st International Heat Stress Genotype Experiment
(CIMMYT, 1992)
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
(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
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 ...

Photosynthetic characteristics of synthetic bread wheats
(CIMMYT, 1994)
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 ...

Research on barley yellow dwarf: state of the art of the CIMMYT program and its future research focus
(CIMMYT, 1994)
This Wheat Special Report is motivated by changes in leadership and funding of CIMMYT's research on barley yellow dwarf viruses (BYD viruses). In 1991, P.A. Burnett, who headed the section in the 1980s, left CIMMYT. R. ...

CIMMYT/NARS Consultancy on ME1 bread wheat breeding: 4-7 April, 1995 Cd. Obregon, Sonora, Mexico
(CIMMYT, 1995)
Through the mechanism of internally managed external reviews (IMERS), all activities of the Wheat Program were reviewed in the period 1990-1994. In general, this was a satisfactory exercise, except that we felt NARS input ...
