An economic survey of cowpea (Vigna unguiculata) storage practices in Kwara State, Nigeria

Recent advances in cowpea [Vigna unguiculata (L

After decades of research on cowpea, significant amount of omics datasets are available and useful in understanding the genetic relationship between Vigna unguiculata ssp. unguiculata and other species belonging to the same genus as well as its genetic variation. Besides, the development of genetic map allowed the chromosome localization of molecular markers associated with disease resistance, ...

Toxic effects of Pb2+ on growth of cowpea (Vigna unguiculata).

A concentration as low as 1 microM lead (Pb) is highly toxic to plants, but previous studies have typically related plant growth to the total amount of Pb added to a solution. In the present experiment, the relative fresh mass of cowpea (Vigna unguiculata) was reduced by 10% at a Pb2+ activity of 0.2 microM for the shoots and at a Pb2+ activity of 0.06 microM for the roots. The primary site of ...

Assessment of genetic diversity in cowpea ( Vigna unguiculata )

Sixty six genotypes of cowpea (Vigna unguiculata (L.) Walp) were investigated to understand the extent of genetic diversity through twelve quantitative traits. Mahalanobis’s D analysis established the presence of wide genetic diversity among these genotypes by the formation of 23 clusters. Cluster I had the maximum number of genotypes i.e 22 and cluster 23 had only one genotype. Intra cluster d...

Analysis of Genetic Linkage in the Cowpea Vigna unguiculata

Genetic analysis of 12 lod conditioning morphological characteristics indicated several linkages in cowpea Vigna unguiculata (L.) Walp). Using both backcross and F2 joint segregation data, these 12 lod were assigned to five linkage groups. The lod Pgfor nodal pigmentation, Pf for purple flower, Pc for smooth seed coat, Na for narrow eye, and Br for brown seed coat make up linkage group 1 with t...
