Wheat breeding for acid soils
1988
Kohli, M.M. | Rajaram, S. (eds.)
The first steps to combine the tolerance of Brazilian wheats to aluminum toxicity with the semidwarf stature, high yield potential, and wide adaptation of the Mexican wheats were taken in the mid-1970s. Under this shuttle breeding operation, crosses between the two germplasm pools are made in both countries and subsequent generations are alternated and selected under local soil and disease pressures. Sometimes the materials of the same generation are grown simultaneously in Brazil and Mexico. Notes on aluminum tolerance of materials are sent to Mexico to permit selection for disease and agronomic characteristics among the lines already determined to be aluminum tolerant. After 12 years of collaboration, many breeding advances have been made, including the transfer of aluminum tolerance to semidwarf wheats. This workshop brought together leading Brazilian and CIMMYT scientists involved in this research to review and share experiences for greater efficiency in future cooperative research
