Identification of adapted varieties of groundnuts (Arachis hypogaea L.) in SEKE BANZA area, Democratic Republic of the Congo (DRC)

Abstract

The present study aimed at identifying the most effective and adapted groundnut varieties to the climatic conditions of SEKE BANZA area, province of Bas Congo, Democratic Republic of Congo (DRC.). Twenty four varieties from IITA /DRC were tested in experimental site of INERA GIMBI. Randomised block design with four replications was used to evaluate grain yields (t/ha), height of plant at the end of flowering(cm), number of days for plant flowering, number of maturity days, stem diameter at the first internodes (mm), Rosette incidence disease(%), Cercospora leaf spots incidence disease (%), Rosette severity (1-5), Cercospora severity (1-5). Compared to controls, ten varieties revealed more effective. Evaluated parameters during season A were higher than during season B. Varieties not released have to be listed on national catalogue before their popularization. In SEKE BANZA area, diseases attack level is low mostly in season A. Number of days for plant maturity was correlated to number of days of plant flowering.
