Abstract
Plant breeding programmes have not been able to maintain the quality of Argentine wheat, so the market transformation involves its quality improvement. A strategy would be to develop quality superior wheat varieties. The protein content and grain yield of the International Maize and Wheat Improvement Center wheat lines were evaluated, to consider the possibility of introducing the elite germplasm material at the time of the implementation of the wheat improvement program for the Argentina central semiarid region. These were compared with national varieties and local experimental lines obtained at Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, Argentina. The experimental evidences suggested that CIMMYT lines stood out because of their high protein content, while the local lines presented the largest protein yields. In this regard, CIMMYT lines may represent a good source of genetic variability to increase the protein content of materials developed for areas where it must be increased.
