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 ...

In Mexico, corn is considered the most important crop, 88% is planted with white corn, 11% yellow and 1% colored, blue or purple corns are rich for their nutritional properties as they contain anthocyanins, characterizing them as special for consumption human. The objective of this research was to estimate selection indices using agronomic and chemical traits in purple maize hybrids in southern Sonora, 19 hybrids and one Creole maize were evaluated in the field and in the laboratory, once the experiment was harvested, the seed was evaluated in the food laboratory of the TecNM-Valle del Yaqui, the agronomic variables were days to female flowering (FF), grain yield (GY), thousand grain weight (TW), hectoliter weight (HW), flotation index (FI), grains per row (GR), rows per ear (RE), ear length (EL), chemical: fat, ash, fiber, protein, carbohydrates and anthocyanins. The results showed stat...
