Developing bread wheats for acid soils through shuttle breeding

1988

Rajaram, S. | Pfeiffer, W. | Singh, R. (CIMMYT, Mexico, DF (Mexico). Bread Wheat Program)

This paper describes the scheme followed by CIMMYT's wheat improvement program in which segregating populations are alternately grown and selected in different locations and succesive generations are alternated between locations (shuttle breeding) to improve adaptation, yield potential, and resistance to diseases and stresses encountered in two distinct locations. The acid soil problem found in many parts of the world is discussed, along with the current situation of wheat production in Brazil, the historical background of Brazil's acid soil problem, the CIMMYT - Brazil collaborative program, and the results obtained by this program in Brazil, CIMMYT, and Mexico. Current production constraints and the future research needs are outlined
