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 ...

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 ...
