Abstract
The field performance of two promising plantain hybrids (FHIA 21 and PITA 3) was conducted alongside a landrace ORISHELE as a control in five different growing conditions in Côte d’Ivoire. Results showed that the hybrids were very tolerant/resistant to the Black Sigatoka disease with high number of functional leaves at flowering and harvest. The hybrid ‘PITA 3’ was early maturing (13 months) compared to 14 months crop cycle for the landrace. The yield performance of the hybrids was superior to the landrace across the locations. FHIA 21 was high yielding with the highest bunch weight (22.40 kg), followed by ‘PITA 3’ (18.40 kg) while the landrace ‘ORISHELE’ produced the smallest bunches (9 kg). The number of fruits per bunch produced by the hybrids was also higher than those of the landrace. However, the landrace produced the longest fruit, and the finger lengths of the hybrid ‘PITA 3’ were the shortest one. Also, the agro-ecological conditions of the Katiola and Bondoukou sites are favorable to the growing of susceptible cultivars to Black sigatoka because the conditions of these sites are unfavorable to the development of the disease. These hybrids can be distributed to farmers to increase their production in the country.
