Genetic Improvement of Yardlong Bean (Vigna unguiculata (L.) Walp. ssp. sesquipedalis (L.) Verdc.)

Abstract

Vigna unguiculata (L.) Walp. ssp. sesquipedalis (L.) Verdc. is commonly known as asparagus bean, Chinese long bean, long-podded cowpea, pea bean, snake bean or yardlong bean, and is an underexploited crop with rich nutritional value. Yardlong bean has evolved and was domesticated from cowpea but differs phenotypically as a result of divergent selection. This crop has its origin in Southeast Asia and its habitat in Asia, Europe, Oceania and North America. It is a warm season crop and besides being a food source, it is used as an ornamental plant and for fodder. Ample germplasm diversity exists in this crop. Major commercial varieties were developed by pure line selection. At present, other breeding methods and principles have limited scope. The presence of genetic diversity in this crop needs to be studied with molecular tools. DNA marker analysis with RAPDs, SSRs and SNPs has begun in yardlong bean. However, genomic studies need to be further developed for the construction of high-density genetic maps and application of modern biotechnology tools. This chapter is an overview of yardlong bean origin, evolution and domestication, general cultivation practices, germplasm biodiversity, characterization, conservation strategies, world and Indian gene banks, biotic and abiotic stress tolerance and crop improvement strategies including conventional breeding, biotechnology, tissue culture and micropropagation.
