A study of the gene B6m, previously described as a modifier, revealed that it is a recessive resistance gene of moderate effect when homozygous. Its value in enhancing resistance to bacterial blight when in combination with other genes, in particular B2, is emphasized. The symbol for the gene is simplified to B6.
