Introduction. The Colombian Altillanura is going through a process of transformation, marked by the expansion of its agricultural border.


In a changing agricultural scenario, characterized by greater environmental protection, climate change and scarcity of irrigation water, the INIA Rice Genetic Improvement Program aims to establish an increasingly sustainable crop, implementing new production methods.
