520			_aMaize is grown in more than 6 million ha in highland environments globally. CIMMYT developed a program to provide improved germplasm for these environments in the 1970's, which was re- oriented toward hard endosperm types in the mid 1980's. Significant gains through recurrent selection have been achieved for grain yield, earliness, reduced plant height and for rust resistance. All the populations are now more inbreeding tolerant.
