A set of recent CIMMYT era hybrids - spanning from the early 1990s to the late 2000s - was analyzed. The hybrids were grown in four different environments in two locations in Mexico: High nitrogen (HN) and low nitrogen (LN) in Agua Fria, and well watered (WW) and water stressed (WS) in Tlaltizapan. A hyperspectral spectrometer was used to take leaf level reflectance data weekly on all plots from late vegetative stages to maturity. In addition, other typical agronomic traits were recorded: grain yield, plant height, ear height, root and stalk lodging, etc. This dataset also contains vegetation indices that have already been calculated for each plot on each sampling date. The data was used to see how traits changed in CIMMYT hybrids over time.
