Bean seed may be received for planting purposes, planted, sold, shipped, or transported if that seed meets one of the following criteria:

(1) The bean variety (cultivar) is known to be uniform for the dominant I-gene. Documentation of evidence of uniformity must accompany the seed shipment. Undocumented cultivars are subject to serology and/or grow out testing to determine freedom from bean seed-borne viral diseases.

(2) The bean seed has been tested by the serology method (ELISA) and is found to be free from bean seed-borne viral diseases.

(3) The bean seed is tested by the serology method and is found to be positive for seed-borne viral diseases and on a subsequent grow out test, the sample is found free from bean seed-borne viral diseases.

(4) All serology tests are based on an official five-pound sample of untreated bean seed for each fifty thousand pounds of bean seed or fraction thereof.
