Phenotypic Analysis of Yield and Yield Components in Mung Bean [Vigna radiata (L.) Wilczek] at Gampèla, Burkina Faso

Abstract

Mung bean (Vigna radiata) is an annual legume that adapts well to dry zones. In Burkina Faso, it is considered an orphan crop. The aim of this study was to gain a better understanding of the crop by evaluating the seed and fodder yields of ten accessions. The accessions were evaluated on thirteen quantitative variables in a Fisher block design with three replications. High genetic variability between accessions was observed. Positive and negative correlations were also observed between variables. Principal component analysis (PCA) explained 65.64% of the total variability between the accessions studied. Accession M06 proved to be the most productive in terms of seed yield (i.e., 3.54 t/ha), whereas M40 reached the highest forage yield (i.e., 3.15 t/ha). Accession M42 was the most judicious, with 95% early maturity (62 days), the highest number of pods (114), good seed yield (3.06 t/ha) and forage yield (2.5 t/ha). These evaluated accessions may be taken into account in future mung bean breeding programs.
