Cowpea [Vigna unguiculata (L.) Walp.]
2014Agrobacterium tumefaciens-mediated transformation is an efficient method for incorporating genes and recovering stable transgenic plants in cowpea because this method offers several advantages such as the defined integration of transgenes, potentially low copy number, and preferential integration into transcriptional active regions of the chromosome ...

Cowpea (Vigna unguiculata (L.) Walp.)
1996The cowpea is an old world crop which is believed to have originated in Africa (Rachie and Roberts, 1974; Ng and Marechal, 1985; Steele et al., 1985). A survey of the germplasm accessions from Nigeria, Niger, Burkina Faso and Ghana showed greater diversity than accessions from other areas in Africa (Ng and Marechal, 1985), leading to the conclusion ...

Studies in Cow-Pea (Vigna unguiculata, (L) Walp.)
Madras Agricultural Journal, 1945Cow-pea has been known and cultivated all over India since very remote tinies. We find an indigenous name for it in all the native languages of India (Watt, 1908). Cow-pea cultivation was introduced into China and other Eastern countries from India in very ancient times. Africa is con- sidered to be the original home of this plant, since the wild forms

Correlation studies in cowpea (Vigna unguiculata (L.) Walp)
Madras Agricultural Journal, 2006Cowpea (Vigna unguiculata (L) Walp.) is wildly distributed throughout the Tropics and Subtropics. It is grown for grain, vegetable and fodder. Genotypic correlation would provide a measure of genetic association between characters and are generally used in selecting for one character as a means for improving another.

Genetic variability in cowpea (Vigna unguiculata(L.) Walp.) genotypes
South African Journal of Plant and Soil, 2015Information on genetic variability among the existing cowpea genotypes will increase the efficiency of the cowpea improvement. Field experiments were conducted at the Agricultural Research Council–Roodeplaat Vegetable and Ornamental Plant Institute in South Africa, in 2011 and 2012, to estimate the level of phenotypic variability among a collection of ...

GENETIC VARIABILITY IN COWPEA (Vigna unguiculata (L.) Walp.)
Madras Agricultural Journal, 1984Variability studies undertaken on forty genotypes of cowpea had shown that there existed greater variability for the traits harvest index, number of pods and seed yield. The least contribution to genetic variability was by number of seeds. per pod. Pod length, 100 seed weight and harvest index recorded higher heri- tability estimates.

"Effects of Uranium on Growth Performance in Vigna unguiculata (L.)"
THE SCIENTIFIC TEMPER, 2022The aim of this article is the determination of uranium concentration in shoots and roots ofbarley (Vigna Unguiculata.), grown on soils, together with its phytotoxic effect on the plantgrowth and development. The soils was contaminated with different doses (12.5μM to 200 μM)of uranyl nitrate.

Characterization of a New Defensin from Cowpea (Vigna unguiculata (L.) Walp.)
Protein & Peptide Letters, 2010Using Phaseoleae defensins available in databases, a putative defensin gene was isolated in cowpea (Vigna unguiculata (L.) Walp.) and cloned from genomic cowpea DNA. The putative mature defensin sequence displays the characteristic defensins residues arrangement, secondary and tertiary structures were predicted and splicing analysis was performed ...
