Corn (Zea mays L.) is the most consumed cereal in México and Latin America, it is important to know the physical quality of the cob and grain to obtain data that serve as a basis for the selection of the best varieties and with it contribute to the conservation and improvement of local varieties, which since the introduction of improved seeds have been at risk of disappearance due to their low yield and poor use. In the spring-summer cycle of 2018, in the town of Cruz Grande municipality of Florencio Villarreal, Guerrero. An experiment was established under a completely randomized block design. The objective was to determine the physical quality of grains and cobs of two genotypes of pigmented corn (red and yellow) belonging to the Dos Puntas variety. The quality of the cob and seed anatomy was evaluated. The results showed that there were no statistical differences between varieties; the grain with the best endosperm is yellow (80.82%) and germ is purple (11.61%); as well as, the yellow variety has a larger grain size (length 10.09 and width 4.31 mm). It is concluded that the corn with the best characteristics for sale as whole grain and use in the dough and tortilla industry, is yellow, and purple for oil extraction.
