Genetic relationships among West African okra (Abelmoschus caillei) and Asian genotypes (Abelmoschus esculentus) using RAPD

Ninety-three accessions of okra which comprises of 50 West African genotypes (Abelmoschus caillei) and 43 Asian genotypes (A. esculentus) were assessed for genetic distinctiveness and relationshipsusing random amplified polymorphic DNA (RAPD). The molecular analysis showed that all the thirteen primers used revealed clear distinction between the two genotypes. There were more diversity amongthe Asian genotypes; this might be due to the fact that they were originally collected from six different countries in the region. Six duplicates accessions were discovered while accession TOT7444 distinguished itself from the other two okra species, an indication which suggests that it might belong to a different species

Classification of genetic diversity and choice of parents for hybridization in cowpea Vigna unguiculata (L.) Walp for humid savanna ecology

Thirty-one accessions of cowpea of diverse eco-geographic origins were evaluated for genetic diversity using principal component analysis (PCA), single linkage cluster analysis (SLCA) and canonical techniques. The accessions were classified into six groups by PCA and SLCA while canonical technique identified five vector groups. There was no relationship between the clustering pattern and eco-geographic distribution. PCA and canonical techniques can be jointly used in multivariate analysisas both techniques performed complimentary role in identifying characters responsible for variation in cowpea. SLCA alone provided a clearer and more informative display of the group of accessions basedon character performance. The three techniques revealed most distant accessions as having widest variation and possible choice of parent stocks in hybridization
