Effect of Gamma Irradiation of Seeds on the Development and Productivity of Three Maize Varieties (Zea mays. L) in Côte D’ivoire

Climate variability has been and continues to be the main source of food fluctuations. This variability threatens the production of cash crops such as maize (Zea mays L). Maize is a cereal and has become one of the main agricultural crops in Côte d’Ivoire. The objective of this study is to determine the agro-morphological characteristics of three (03) varieties of maize (EV 8728, GMRP / 18 and MDJ) which have undergone irradiation with gamma radiation (0, 100, 200 and 300 grays) to induce mutations. The agro-morphological evaluation was carried out in a completely randomized block device. morphological characters selected from the descriptors of maize were used in this study. The descriptive analysis revealed a significant diversity between the treatments. The comparison between all the agro-morphological characters and the different treatments showed that the treatments EV8728_0 and EV8728_100 Gy had the best characteristics of ears and grains and the treatment MDJ_200 had the best vegetative characteristics.
