Determination of pedigrees based on genetic composition.



It provides a framework upon which to organize marker-trait associations, which are utilized in breeding programs to select parents for crosses, and progeny from crosses.

Target Beneficiaries

Cowpea breeders, cowpea germplasm managers, and basic research scientists who with to pursue the mechanistic basis of marker-trait associations or comparative genetic studies between legumes.

Innovation Description

The cowpea nuclear genome is composed of eleven chromosomes, each carrying thousands of genes within the nucleotide strings that comprise each chromosome. Allelic variants exist within the genes and are the basis of trait variation.These and other variants outside of the genes include millions of nucleotide variations. Using populations of closely related progeny, the recombinational distances and the commercially available genotyping tool that this IL developed, a genetic linkage map containing more than 35,000 positions was developed.

Competitive Advantage

The density of this genetic map is approximately a 30-fold increase in the density of any previously existing cowpea genetic linkage map.
