ESPINOSA-CALDERON, Alejandro et al. Grain yield of maize varieties with yellow  endosperm and earliness for Mexican highlands. Agron. Mesoam [online]. 2013, vol.24, n.1, pp.93-99. ISSN 2215-3608.

The objective in this work was to evaluate the  grain yield capacity of yellow grain maize varieties  developed in The Cuautitlan Faculty of Superior  Studies, of the Autonomous National University  of  Mexico  (FESC-UNAM),  and  the  National Institute for Forestry, Agricultural and Livestock, Research (INIFAP). Two experiments were planted in two locations; one in the CEVAMEX, in Saint Lucia of Prias and another at the FESC-UNAM, compared to white grain and yellow commercial control groups; both were planted mid June, 2010. Thirteen maize varieties were evaluated in each experiment under a randomized complete block design with three replications. The site of CEVAMEX had the best grain yielding, 5887 kg/ha, and was superior (p ≤ 0.05) to the experiment of FESC-UNAM (3799 kg/ha). The best grain yielding varieties were ORO ULTRA UNAM C (6913 kg/ha), V-55 A (6284 kg/ha), V-53 A (6035 kg/ha) and A V-54 (5405 kg/ha).
