ABSTRACT: A study was carried out on 31 new hybrids in rain-deficient areas of Côte d’Ivoire. These areas were the regions of Djekanou, Toumodi and Yamoussoukro. The Divo region (favourable zone) was used as a control. The aim of this study was to determine the behaviour of these hybrids under drought conditions. The experimental setup was a Fischer block for each region. The treatments were the 31 families, with 3 replications and when the four regions were taken together, the study was a two-factor (region and family) trial. Drought caused increased mortality and specific leaf mass and reduced growth and development of progeny in rain-deficient areas. Five (5) progenies were found to be jointly successful in Divo, Djekanou and Yamoussoukro (F30, F15, F19, F31, and F33). On the other hand, 3 other families (F16, F36 and F29) also performing well in Divo were found in Toumodi.
