Abstract:Vigna unguiculata (L.) Walp., commonly known as cowpea, is recognized as a primary pulse crop by Food and Agriculture Organization. Cowpea is a nutritious and versatile crop, which has the ability to withstand higher atmospheric temperature. However, the crop is low yielding as compared to other pulse crops, and different breeding strategies have been employed from time to time to enhance the yielding potential and overall agronomy of the crop. Among the breeding strategies, mutation breeding has been the most successful in increasing the yield and genetic variability in the existing cowpea cultivars. In mutation breeding, the selection of an appropriate mutagen, mutagen dose and genotypic sensitivity, and mutagenic effectiveness and efficiency are important aspects that determine the success of crop improvement programs. In addition to mutation breeding, advanced molecular breeding has also achieved milestones in the genetic improvement of cowpea. Therefore, this chapter presents a brief review of important literature of various aspects particularly related to mutation and molecular breeding of cowpea.
