The experiment consisted of two cowpea varieties IT97K and IT93K and weed control treatments Metolachlor at 2 levels of 1. The treatments were factorially combined and laid out using split plot design with variety assigned to the main plot and weed control treatments to the sub plots.
Cowpea plants stand behind them.
Cowpea provides food that complements starchy staple crops such as corn, cassava, sorghum and millets to offer a well-rounded diet, much as beans and Cowpea research paper grain legumes complement maize- and rice-based diets in Latin America and other places.
Due to its hardy nature, cowpea plays a key role in sustaining food security for both people and their livestock. But breeding new cowpea varieties with desirable traits, such as disease resistance, pest resistance and drought tolerance, is a time-consuming and laborious process that can take a decade from concept to release.
A challenge facing cowpea breeders, therefore, is how to accelerate the production of new and improved cowpea varieties in order to both meet the needs of a growing world population and provide the productivity gains needed by farmers to improve their economic standing. To build the map, the scientists first modified and then applied advanced genetic tools developed from human genome investigations that only recently have been applied to a few major crop plants.
The consensus genetic map of cowpea is a dense and detailed roadmap of its genome a genome is a complete genetic blueprint. The map has approximately molecular markers throughout the genome. The markers, which are like signposts directing a motorist to a destination, are associated with traits desired for breeding and used to more deliberately design and assemble new superior varieties.
Agency for International Development, that has assisted African institutes in developing improved cowpea varieties. This facilitates knowledge transfer between these species, so advances made in cowpea can be translated into valuable information for soybean, and vice versa.
The result is a tremendous acceleration in marker development to support the breeding process. In the United States, cowpea is popular in the south, where it is known as black-eyed peas and other names.
California primarily grows the blackeyed cowpea type. The new consensus map will greatly expand our ability to locate valuable genes and incorporate them into new varieties.
These genetically diverse varieties offer a treasure-trove of genes of potential value to breeders seeking to build better cowpea varieties.
UCR researchers have been providing assistance to African scientists for several decades. He also led the effort to establish a genetic map for cowpea, published in Genetic diversity of cowpea seed.•HIND AGRICULTURAL RESEARCH AND TRAINING INSTITUTE Research Paper Received: February, ; Accepted: March, HIND AGRICULTURAL RESEARCH AND TRAINING INSTITUTE cowpea as influenced by intercropping and nitrogen fertilizer in the lowland humid tropics.
J. Sustainable Agric. FAO, national statistics and the Bean/Cowpea Collaborative Research Support Program (CRSP), this paper consolidates information on cowpea production, marketing and trade in West and Central Africa and examines the effects of grain. The genetic diversity of cowpea was analyzed, and the population structure was estimated in a diverse set of 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 . A Country Case Study of Cassava Development in Ghana.

Cassava is a major crop in the farming systems of Ghana. UC Riverside Researchers Develop Genetic Map for Cowpea, Accelerating Development of New Varieties.
Map also facilitates genetic improvement of several other legumes as well as Prasanna Bhat, Raymond Fenton, Steve Wanamaker, and Marti Pottorff. Other coauthors on the research paper are Sarah Hearne and Christian Fatokun of the . This report is unique in presenting a high-resolution dataset of biomass use, production, feed efficiencies, and greenhouse gas emissions by global livestock.
This information will allow the global-change research community in enhancing our understanding of the sustainability of livestock systems.
