Mucuna is a genus which has numerous species of climbing lianas (vines) and shrubs of the family Fabaceae, tribe Phaseoleae and is generally located in the tropical forests. This book reviews the utilization of biochemical and molecular genetic approaches for studying the genetic variation and phylogenetic relationships of Mucuna germplasm in order to provide developed strategies for plant improvement. This book is of interest to plant geneticists, plant breeders, researchers, and scientists.
