Abstract

In Holguin, Cuba, maize (Zea mays, L.) is mainly
grown in the winter season, the period of lowest levels of
rainfall in the year. This kind of management, together with the
poor availability of dry-weather resistant materials has
contributed to a decrease in the yields of this cereal in the last
few years. For this reason and due to the necessity of having
cultivars that adapt to these conditions, the present work is
intended to evaluate 20 accessions of maize, including
accession Gibara as a local witness, under drought conditions
in two edafoclimatics areas of Gibara municipality in Holguín.
These accessions were evaluated considering their
morphological traits (vegetative component and yield) and on
this base, the effect of the genotype x environment interaction
was studied in two areas of this municipality, using an AMMI
(additive main multiplied interactions) analysis. It was possible
to determine those accessions that showed good genetic
stability in the two areas studied, e.g. accessions: 26, 44, 46,
106, 125 and the local witness, what allows recommending them
as the best adapted for the dry weather conditions in Gibara
municipality.
