The Natural Resources Institute (NRI) and the International Institute of Tropical Agriculture (IITA) are collaborating to develop sex pheromone traps as monitoring tools for Maruca vitrata. The principal component of the pheromone is (E, E)-10, 12-hexadecadienal. Our trapping experiments in cowpe...

IITA’s Genetic Resources Center (GRC) maintains over 15,000 accessions of cowpea (Vigna unguiculata L.) and wild Vigna which is available and distributed worldwide for research in food and agriculture. Since 1985, IITA has distributed germplasms for cowpea genetic improvement research to institut...

Cowpea is seed propagated and when mature seeds are properly dried they could remain viable over a period of time depending on the genotype and storage conditions. Due to heat and dry conditions seeds of cultivated cowpea that remain in the fields after harvest usually do not retain viability for...

For a mixture of reasons certain tropical crops which are important as primary or secondary food staples are relatively underresearched. The modem tools of molecular and cellular biotechnology offer the opportunity not only to make substantial gains in our knowledge of these crops, but also to ov...
