Twelve landraces of kersting's groundnut (Kerstingiella geocarpa Harms), collected from northern Ghana in 2004 were evaluated for plant height, canopy spread, leaf area index, nodule count, days to 50% flowering, fresh and dry shoot weight, fresh and dry root weight, pod number per plant, grain yield and hundred seed weight. The following parameters were similar (p > 0.05) among the landraces: leaf area index, nodule count at 7 and 9 WAP, dry shoot weight at 7 WAP, fresh and dry shoot weight at 7 WAP, number of pods per plant and hundred seed weight. Plant height at 8 WAP significantly varied (p = 0.026) among the landraces. The landraces Boli, Heng milk mottled, Gbangu, Nakori and Puffeon produced the tallest plants. Canopy spread of Heng red mottled, Heng milk mottled, Boli, Nakori, Nankpaduri, Puffeon and Gbangu exceeded other entries at 9 WAP. Days to 50% flowering varied significantly (p = 0.001) among landraces with Puffeon, Gbangu, Heng milk mottled, Nakori and Heng red mottled flowering early. At 7 WAP, fresh shoot weight was significantly (p = 0.002) different among the landraces with Heng milk mottled, Funsi, Nankpaduri, Boli, Sigiri, Dugulatuk, and Gbangu outstanding. Grain yield was highly significant (p = 0.001) with Heng red mottled, Funsi, Puffeon, and Sigiri as best yielders. Six Principal components (PC) were significantly informative in a factor analysis. The PC1 contained 90.76% of the total variation in the collection. A cluster analysis revealed that the measured traits accounted for only 12% of the variation with two major clusters.
