International TRIGO (Wheat) Yield Potential, Proceedings; Cd. Obregon, Sonora, Mexico; 24-26 Mar 2015
The abstracts herein are of presentations by crop experts for the “TRIGO (Wheat) Yield Potential Workshop”. Sponsored by SAGARPA’s international strategic component for increasing wheat performance, under the Sustainable ...
Genetic diversity for photosynthesis in wheat under heat-stressed environments and its relationship to productivity
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 ...
Evaluation of membrane thermostability and canopy temperature depression as screening traits for heat tolerance in wheat
The production of wheat germplasm with resistance to high temperature increases in importance with world wheat demand. Temperatures considered above optimal for wheat growth and development of presently grown varieties are ...
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 ...
Intercropping cereals with N-fixing legume species: a method for conserving soil resources in low-input systems
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 ...
Complementary strategies to raise wheat yield potential: book of abstracts
The abstracts herein are of presentations by world-renowned experts for the workshop “Complementary strategies to raise wheat yield potential” (10-13 November 2009, CIMMYT-El Batán, Mexico). Sponsored by the United States ...
International Symposium on Wheat Yield Potential: Challenges to International Wheat Breeding
Like many other patterns, investment in research is often cyclical. International centers like CIMMYT have focused substantial resources on biotic and abiotic stresses for about two decades now, but raising total productivity ...
International Wheat Improvement: Highlights from an Expert Symposium
Wheat is grown on 217 million hectares worldwide, accounting for some 620 million tons of grain and providing one-fifth of the world’s total calorific input. In regions like North Africa, Turkey, and Central Asia, wheat ...
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 ...
