However, about 31.2% of the population suffers nutritional problems, so it is important to increase the nutritional quality of the maize kernel through the modified opaque-2 corn or quality protein maize (QPM), as well as to-develop hybrids with high yield for tropical and subtropical areas of Mexico. It is also important to involve new techniques such as molecular markers in order to reduce the time and effort to find parents with the best general combining ability (GCA) for hybrids. The objective of this project was to determine the GCA of 14 QPM tropical lines from CIMMYT and find the best single crosses.Collection: CIMMYT Staff Publications Collection
