The agronomic importance of the fruit or pod of common bean lie in its use as a dry legume as its most recent use as fresh or processed vegetable. The expected project outcomes include genetic dissection of the characters involved in pod development, which will help improvement strategies to control the string and seed dispersal, and consequently the yield and quality of a crop of economic importance such as common bean. While we understand the genetic mechanisms that regulate these characters will also be possible to investigate its evolution during domestication occurred in common bean.
