Description

A poster presented at the 2012 Global Pulse Researchers Meeting, Kigali, Rwanda- “Transforming Grain-Legume Systems to Enhance Nutrition and Livelihoods”. Abstract: The common bean weevil (Acanthoscelides obtectus Say) is a major seed storage pest of beans (Phaseolus vulgaris L.). A population expected to segregate for resistance to the bean weevil was obtained from Oregon State Univ. A bioassay was developed and used to screen bean lines for resistance to the bean weevil in two trials conducted during 2011. Seed of both Andean and Middle American bean cultivars were severely damaged by the bean weevil. The bean weevil resistant line AO1012-29-3 was crossed with white and black lines that have commercial seed type and BGYMV and BCMNV resistance. Individual plants with local adaptation will be selected and screened for resistance to BCMNV. Resistant lines will be screened for the presence of the bgm gene and the I gene using molecular markers.
