Caracterisation Agro-Morphologique Des Accessions D’arachide (Arachis Hypogaea L.) Pour La Teneur En Huile

Abstract

In Niger, groundnut [Arachis hypogaea (L.)] is a leguminous crop cultivated in large area. Its seeds are used by oil industries. Groundnut oil is well appreciated by consumers notably in rural areas. The aim of this study was to select the accessions and taxa with high oil content and identify the oil content related traits. Thus, 20 accessions (9 local and 11 improved) belonging to 5 taxa types (FST, VUL, PRU, HYR, and HYB) were planted in randomized block design with three replications. Fifteen traits were investigated in field while oil content was quantified in laboratory. An analysis of variance was performed on all measured traits. Discriminant factorial analysis (AFD) was performed on taxon types, correlation between oil content and other traits was determined. Analysis revealed high and significant correlation between oil content and seed size. In the study, groundnut accessions ICG 8352 and ICG 9991 (oil content 52.8%) and taxon Fastigiata (oil content 48.52%) recorded highest oil content. Seed size and taxon type in groundnut could be criteria to select genotypes for oil industries.
