Breeding resistance to yellow (stripe) rust in wheat
(CIMMYT, 1997)
The information contained in this paper is a precis of the PhD thesis of Dr. H.P. Bimb. Since yellow (stripe) rust has recently reared its head in West and South Asia, the rapid publication of this Wheat Program Special ...

Sustaining wheat yields with crop management in heat stressed environments: effect of organic and inorganic fertilizers, mulching, and irrigation frequency
(CIMMYT, 1998)
Wheat (Triticum aestivum L.) emend. Thell) yield reduction associated with heat strees is a worldwide problem. The objectives of this research were to (i) to determine effects of major crop management factors on performance ...

CIMMYT/NARS Consultancy on ME1 bread wheat breeding: 4-7 April, 1995 Cd. Obregon, Sonora, Mexico
(CIMMYT, 1995)
Through the mechanism of internally managed external reviews (IMERS), all activities of the Wheat Program were reviewed in the period 1990-1994. In general, this was a satisfactory exercise, except that we felt NARS input ...

Wheat breeders' perspectives on genetic diversity and germplasm use: findings from an international survey
(CIMMYT, 1996)
Although there is much debate about the role of scientific plant breeding in the possible reduction of genetic diversity in commercially grown crop plants, few studies have recorded breeders' actual use of materials and ...

Management and use of international trial data for improving breeding efficiency
(CIMMYT, 1992)
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 ...

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 ...

Evaluation of membrane thermostability and canopy temperature depression as screening traits for heat tolerance in wheat
(CIMMYT, 1993)
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
(CIMMYT, 1993)
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
(CIMMYT, 1991)
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 ...

Increasing the yield potential of irrigated bread wheat: basis for physiological research at CIMMYT
(CIMMYT, 1992)
Yield potential (YP) is defined as the "yield of a cultivar grown in environments to which it is adapted when nutrients and water are nonlimiting, and when pests, diseases, weeds, lodging, and other stresses are effectively ...
