The production of corn (Zea mays L.) in Mexico is deficient despite producing 27 million tons, in the last four years the production of corn in Sonora has increased, producing from 544 to 680 thousand tons in 2018 and 2021 respectively, 97% of the production corresponds to white corn, 3% to yellow corn; however, in colored maize there are no planting records. The objective of this research was to estimate grain yield and its agronomic components in improved purple maize hybrids in southern Sonora. A randomized complete block experimental design was used with three repetitions with the AMMI model, the plots were two rows four meters long with a population density of 100,000 plants per hectare, the variables were: grain yield, seed weight, thousand grains, ear length, grains per row, rows per ear and test weight. The results showed statistical significance between hybrids, years and their ...
