Nuñas are a type of common bean (Phaseolus vulgaris) that possess the unusual characteristic of popping or expanding their cotyledonary tissue when heated. Numerous landraces of nuña beans were domesticated in the Andean region of South America (Peru, Bolivia, and Ecuador) and have been grown and consumed in this region since antiquity. The practical consideration in the domestication of nuñas in the high Andes was likely due to the greater energy efficiency in cooking toasted vs. boiled seeds.The Phaseolus germplasm bank at CIAT (Centro Internacional de Agricultura Tropical) has developed a core collection of Andean beans that includes numerous nuña landraces. Based on the wide range of phaseolin types observed among nuña landraces, it has been hypothesized that nuñas may represent a greater source of genetic diversity compared to other landraces and cultivars of common bean. Eighty nuña accessions and 120 nonpopping common bean accessions were randomly sampled from the CIAT Andean germplasm core collection. The 200 accessions were characterized for 140 mapped RAPD markers. The objectives of our research were to 1) understand the genetic structure of nuña bean accessions relative to other Andean common beans, and 2) to measure the genetic distance and genetic diversity between nuña and other Andean bean populations.
Common bean ( Phaseolus vulgaris ) is the most important legume grown for direct human consumption ( Singh, 1999 ). It is cultivated principally for its dry seeds, green shelled seeds, and immature green pods, called snap beans. Snap beans are grown
four lines were planted on 23 June 2008 and crossed in a 4 × 5 diallel mating design to five selected snap bean cultivars: ‘Amy’ (Seminis, St. Louis, MO), ‘Teresa’ (Seminis), and ‘PV712’ (Pop Vriend, Andijk, The Netherlands), which are currently grown
