A guide to the CIMMYT Crop Management and Physiology Subprogram
Emphasis in presenting developments and achievements of Crop Management and Physiology (CMP) will be placed on the period dating from 1988. This is when the strategic plan was formulated (although not published until 1989), ...
Increasing the yield potential of irrigated bread wheat: basis for physiological research at CIMMYT
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 ...
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 ...
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 ...
Wheat production and grower practices in the Yaqui Valley, Sonora, Mexico
Wheat yields in the Yaqui Valley of NW Mexico have appeared to remain stable in the past decade despite the release of new varieties and improved agronomic recommendations. A study was conducted during the winter of 1990/91 ...
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 ...
Photosynthetic characteristics of synthetic bread wheats
In the process of genetic improvement of bread wheat, photosynthetic rate per unit leaf area has decreased significantly from the maximum photosynthetic rate (Pmax) of the crop's diploid ancestors (donors of the A, B, and ...
