Lablab legume belongs to the family Fabaceae and is native to Africa. It is cultivated worldwide for its highly nutritive value. The plant is variable due to the extensive breeding in cultivation. Its wild species are perennial. This book highlights the potential uses of molecular genetic markers for investigating the genetic variability and relationships of Lablab genetic resources in order to enhance the crop yield and production. This book is of interest to plant geneticists, plant breeders, researchers, and scientists.
