Management and use of international trial data for improving breeding efficiency
The Germplasm Improvement Subprogram organized a workshop and think-tank on management and use of international trial data for increasing breeding efficiency at Ciudad Obregon, Mexico on January 21-22, 1992. Participants ...
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 ...
Vernalization requirement and response to day length in guiding development in wheat
Vernalization requirement and response to day length are the major factors controlling development in wheat (Triticum aesitvum L.). This study was to determine how they integrate in the field in Obregon, Sonora, Mexico to ...
Russian wheat aphid research at CIMMYT: current status and future goals
A few years ago, CIMMYT started working on the Russian Wheat Aphid (Diuraphis noxia) on a very small scale. Reports on the spread and damage due to this aphid's attack are on the increase in both developed and developing ...
Canopy temperatures of wheat: relationships with yield and potential as a technique for early generation selection
It is shown that, for bread wheat, air-canopy temperature difference correlates significantly with grain yield, especially when measurements are taken later in the day, We discuss the potential of this technique as an early ...
Semidwarf bread wheats: names, parentages, pedigrees, and origins
One of CIMMYT's primary functions is to produce germplasm for use by cooperating national crop improvement programs. In the development of wheat germplasm, emphasis is given to producing advanced materials that can be ...
Identification and characterization of resistance to the Russian wheat aphid in small-grain cereals: investigations at CIMMYT, 1990-92
It is only recently that the Russian wheat aphid [Diuraphis noxia (Mordvilko)] has become a serious pest of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) outside its primary range of the mountains of ...
Fusarium head scab of wheat (Fusarium graminearum Schwabe)
Scab or head blight of wheat, caused by the fungus Fusarium graminearum Schwabe, was first described in 1891 by Arthur in the United States (2); it was later reported in Japan in 1902. In Mexico the disease was detected ...
Assessment and development of an agricultural research station: physical and personnel needs
The agricultural research station plays a vital role in the generation of both new knowledge and appropriate technologies for farmers. However, despite the importance and complexity of running research stations, there is ...
