Abstract
A new approach in the breeding of potatoes in Mexico is described, in which the progenies of different crosses are evaluated in consecutive plantings under different ecological conditions in three zones with different growing seasons. Yields and manipulation of the genetic material were adequate in all the three zones. The new system saves as much as 40% in time as compared with the conventional breeding programs. Some of the selected clones outyielded the control by 50% to 150%. Other implications and advantages of the system are discussed.
Resumen
Se describe un procedimiento de mejoramiento de la papa en México, en el cual las cruzas y las progenies del material genético se evalúan en siembras sucesivas en tres zonas con fechas de siembra y ecologías diferentes. La manipulación y el rendimiento del material fueron adecuados en todas las zonas y permiten ahorrar casi un 40% del tiempo requerido en los programas convencionales de mejoramiento. Algunos de los clones seleccionados sobrepasaron al Testigo en rendimiento en 50–150%. Se discuten tambien otras ventajas e implicaciones del sistema.
