Abstract

Abstract : The bean weevil ( Acanthoscelides obtectus Say) is an aggressive post‐harvest pest of the common bean ( Phaseolus vulgaris L.). Bean common mosaic virus (BCMV) and Bean common mosaic necrosis virus (BCMNV) are important seedborne diseases of dry bean in the Americas and Africa. The development of bean lines that combine resistance to BCMV, BCMNV, and bean weevils can help to reduce yield loss during the growing season and avoid seed damage during storage. AO‐1012‐29‐3‐3A, (Reg. No. GP‐299, PI 675563) is a multiple virus and bean weevil‐resistant bean germplasm line adapted to the humid tropics; it was developed and released cooperatively in 2015 by Sokoine University of Agriculture, Oregon State University, the USDA‐ARS, and the University of Puerto Rico. AO‐1012‐29‐3‐3A has a determinate growth habit and a dark red kidney seed type similar to the cultivar Rojo, which is commercially acceptable in Tanzania. AO‐1012‐29‐3‐3A possesses the I and bc‐1 2 genes that confer resistance to BCMV and BCMNV. AO‐1012‐29‐3‐3A produced a mean seed yield similar to the checks USLK‐1 and 'Badillo' in three trials planted in Puerto Rico. Seed of AO‐1012‐29‐3‐3A had greater levels of threonine, proline, analine, valine, lysine, methionine, and crude protein compared with the check cultivar Badillo. AO‐1012‐29‐3‐3A should serve as a useful source of resistance to the bean weevil, BCMV, and some pathogroups of BCMNV.
