Evaluation of corn (Zea mays L.) hybrids in corn growing areas of Ecuador
Main Article Content
Abstract
This research was conducted during the dry season in two corn production zones of the Ecuadorian coast, the selected locations were the province of Santa Elena, El Azúcar sector, and the province of Los Ríos, Puerto Pechiche sector. The purpose was to evaluate the adaptability of new high yielding corn (Zea mays L.) hybrids in two corn production zones of Ecuador. A factorial design with six corn hybrids and two production zones was used. Statistical analysis indicated significant differences for: plant height, day of flowering emergence, disease incidence, ear insertion height, ear diameter and length, number of rows, 100 kernel weight, ear cover, percentage of lodged plants, percentage of ears with rot and yield per hectare. The hybrids with outstanding agronomic and yield characteristics were ADV248, followed by ADV407 and ADV762L6.
