In the Katanga, in the peasant environment the middle yield of corn oscillates between 800 and 1000 kg.ha-1 against respectively 3000 to 4000 kg.ha-1 and 6000 to 8000 kg.ha-1 in the big agricultural exploitations and in the stations of research. To solve the problem of deficit and dependence opposite the outside, the experimentations have been led to Kasapa farming to value effective varieties of corn. Fourteen varieties of corn exits of the Business Pannar, Republic South African have been valued. Every variety has been sowed as using a device in complete blocks randomized with three repetitions and these varieties has been compared to Unilu and Katanga varieties selected by the faculty of agricultural sciences/University of Lubumbashi and the Babungo variety selected by the National Institute of Study and agricultural research. All varieties tested in the soil and climate conditions of the city of Lubumbashi gave similar yields to those of the local witnesses. In the context of the province of the Katanga, the varieties adapted to the climatic conditions degenerated and don't permit to achieve some good yield anymore. Besides, with the climatic change observed these last decades, the effective variety selection will permit to put at the disposal of the peasants of the varieties of corn adapted to the climatic conditions degenerated and to good potential of yield in grains.

Abstract
In the Katanga, in the peasant environment the middle yield of corn oscillates between 800 and 1000 kg.ha-1 against respectively 3000 to 4000 kg.ha-1 and 6000 to 8000 kg.ha-1 in the big agricultural exploitations and in the stations of research.

Fourteen varieties of corn exits of the Business Pannar, Republic South African have been valued.

Abstract: (french)
Au Katanga, dans le milieu paysan le rendement moyen du maïs oscille entre 800 et 1000 kg.ha-1 contre respectivement 3000 à 4000 kg.ha-1 et 6000 à 8000 kg.ha-1 dans les grandes exploitations agricoles et dans les stations de recherche. Pour résoudre le problème de déficit et de dépendance vis-à-vis de l'extérieur, les expérimentations ont été menées à la ferme Kasapa pour évaluer des variétés performantes de maïs. Quatorze variétés de maïs en provenance de la Firme Pannar, République Sud-Africaine, ont été évaluées. Chaque variété a été semée en utilisant un dispositif en blocs complets randomisés avec trois répétitions et ces variétés ont été comparées aux variétés Unilu et Katanga sélectionnées par la faculté des sciences agronomiques Université de Lubumbashi et la variété Babungo sélectionnée par l'INERA. Toutes les variétés testées dans les conditions édaphoclimatiques de la ville de Lubumbashi ont donné de rendements similaires à ceux des témoins locaux. Dans le contexte de la province du Katanga, les variétés adaptées aux conditions climatiques ont dégénéré et ne permettent plus de réaliser des bons rendements. En outre, avec le changement climatique observé ces dernières décennies, la sélection des variétés performantes permettra de mettre à la disposition des paysans des variétés de maïs résilientes au changement climatique et à bon potentiel de rendement en grains.
