This study used two maize populations from “Criollo de Queredo” and “ETO × USA 342-4#” in Ecuador to; (1) study the phenotypic variation exhibited by the two open-pollinated maize populations that are being used as basic germplasm pools in a long-term corn improvement program; and (2) to estimate selection progress from the first cycle of the modified ear-to-row procedure.
Large phenotypic variation was exhibited in both populations in five important agronomic characters measured. Yield ranges expressed in percent of the mean were considerably higher than those for plan height, ear height, days to flower and moisture percent at harvest in the two populations.
