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 ...
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 ...

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
Cultivo intercalado de cereales con especies de leguminosas que fijan N: un metodo para conservar los recursos del suelo en sistemas de bajos insumos
(CIMMYT, 1994)
La producción de cereales con pocos insumos y gran eficiencia contribuye a aliviar la pobreza, incrementa los ingresos agrícolas y favorece la conservación del medio ambiente (1os suelos y el agua). Este Informe Especial ...

Conference Proceedings
Increasing yield potential in wheat: breaking the barriers. Proceedings of a workshop held in Ciudad Obregon, Sonora, Mexico
(CIMMYT, 1996)
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 ...

Report
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 ...
