Objectives
The productivity of a maize variety depends on both its genetic characteristics and the soil and climate conditions where it is grown. The growing environment of a maize plant, including the weather, the soil in all its aspects, the amount of light, water and nutrients available to the plant in different stages of growth, strongly determines how its genes are expressed and thus the final yield. For this reason, farmers may have some indications on which varieties are better suited to certain conditions, but they cannot be 100% sure on the final yield, due to complex interactions between genetic and environmental characteristics. Within hte DROPS project 246 maize hybrids were tested in 25 different plots distributed between Europe and Chile to determine which maize genes are better adapted to each environment.

Activities
Researchers monitored field conditions with sensors and measured the yield of different maize hybrids to make a statistical model for predicting the yield of each hybrid, taking into account its genes and the environmental characteristics of an area. This model will help to characterise genetic resources so as to improve breeding programmes and obtain new hybrids which will be more adapted to climate change. The model will also be very useful for farmers to assess which hybrids will produce more yield in a certain plot and thus help them to adapt their farm management and reduce the impact of climate change.
