Emphasis has been placed on the screening of hybrid selections for resistance to rust, anthracnose, BCMV and Empoasca sp., yield and sensitivity to photoperiod. A total of 1464 materials (937 selections from the breeding program) were screened in the Bean Team Nursery and 700 (200 breeding selections) in the Preliminary Yield Trial. Results from the latter demonstrated major gains in yield among colored materials and a very high proportion of lines resistant to BCMV. Many lines demonstrated multiple-disease resistance.
