Estudios realizados en la zona sur de Chile para el periodo 1961-1991, indican que el avance con que el mejoramiento genetico ha contribuido en esta zona es de 2.6 t/ha, y que el manejo del cultivo ha aportado 3.1 t/ha. El avance total experimentado por el cultivo en este periodo es de 5.7 t/ha. Mycosphaerella graminicola se presenta en todas las zonas productoras de trigo en Chile, afectando principalmente las siembras tempranas en areas de alta pluviometria. El manejo de la enfermedad ha incluido siembras adecuadas al tipo de variedades, rotacion de cultivos, la seleccion de materiales tolerantes y la evaluacion de fungicidas efectivos y momentos de aplicacion.|An average yield for wheat of 3 t/ha on has been obtained during the last five growing seasons in Chile. This is twice the yield obtained until 1983. Studies conducted in southern Chile over a 30-year period have shown that 2.6 t/ha are due advances in breeding, and 3.1 t/ha are due to improvements in crop management. Thus, between 1961 and 1991 wheat crop production research has brought about an improvement of 5.7 t/ha. Mycosphaerella graminicola is found in all wheat producing areas in Chile, affecting most of the wheat planted early in rain areas. Disease management has focused on planting time according to the germplasm, crop rotation, selection of tolerant germplasm and screening of effective fungicides and application time.Collection: CIMMYT Publications Collection
