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 ...
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 ...
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 ...
