    Abstract Knowledge of the genetic components of agronomic traits is an important factor to characterize landraces of maize to make them useful in plant breeding programs. The objective of this work was to know the genetic action and combining ability of several agronomic traits of five maize races and their crosses. Maize landraces analyzed were Jala, Tuxpeño, Celaya, Pepitilla and Dulce. Plant height, days to male and female flowering date after planting, and dry matter and grain yields were recorded. Those variables showed highly significant differences among genotypes. With the exception of dry matter yield, the other variables showed significant general… More >
