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...
متن کاملGenetic diversity of Rhizobia isolates from Amazon soils using cowpea (Vigna unguiculata) as trap plant
The aim of this work was to characterize rhizobia isolated from the root nodules of cowpea (Vigna unguiculata) plants cultivated in Amazon soils samples by means of ARDRA (Amplified rDNA Restriction Analysis) and sequencing analysis, to know their phylogenetic relationships. The 16S rRNA gene of rhizobia was amplified by PCR (polymerase chain reaction) using universal primers Y1 and Y3. The amp...
متن کاملAnalysis 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...
متن کاملRecent 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, ...
متن کاملGenetic Diversity and Population Structure of Cowpea (Vigna unguiculata L. Walp)
The genetic diversity of cowpea was analyzed, and the population structure was estimated in a diverse set of 768 cultivated cowpea genotypes from the USDA GRIN cowpea collection, originally collected from 56 countries. Genotyping by sequencing was used to discover single nucleotide polymorphism (SNP) in cowpea and the identified SNP alleles were used to estimate the level of genetic diversity, ...
