A Mexican grass which is grown as fodder and is considered to be one of the parent plants of modern maize.
Zea mays subsp. mexicana, family Gramineae.
For decades plant biologists have been arguing about whether domestic maize is really a descendant of teosinte, a Mexican grass....
Consequently, they will help to increase our understanding of the gene-flow process in Mexico and Central America where teosinte and maize populations grow in geographic proximity and flower synchronously.
We also examine genetic variation in teosinte for several quantitative traits that differentiate maize and teosinte.
Origin
Late 19th century: from French téosinté, from Nahuatl teocintli, apparently from teo:tl 'god' + cintli 'dried ear of maize'.
