Adaptation of wheat to the canopy environment: physiological evidence that selection for vigor or random selection may reduce the frequency of high-yielding genotypes
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 ...
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 ...
