Interpretive Summary: Common bean, or Phaseolus vulgaris, is a very important crop throughout the world. There are, however, many breeding and production challenges. The crop is susceptible to many diseases, including bacterial, fungal, and viral diseases and various insect and nematode pests. Other challenges include drought, soil nutrient deficiencies, and heat stress - which causes infertility in the plant. This review describes breeding objectives for beans (of various types), and breeding approaches and genetic resources. This review should provide bean breeders with information that they can use to produce new bean varieties to help solve the breeding challenges for this crop.
Technical Abstract: Common bean is a vital food source for a large portion of the human population worldwide. Despite its importance, the crop faces many challenges - biotic challenges including a wide range of bacterial, fungal, and viral diseases and various insect and nematode pests; and abiotic challenges including drought, soil nutrient deficiencies or toxicities, and heat stress and associated infertility. This review describes the wide range of breeding objectives for this complex, multi-faceted crop, as well as genetic and genomic resources. The review also briefly outlines genetic databases for the crop and breeding methods in use for bean improvement.
