In this study, we identify eight putatively nonfunctional alleles of the\n                    <jats:italic>BADH2</jats:italic>\n                    gene and show that these alleles have distinct geographic and genetic origins. Despite multiple origins of the fragrance trait, a single allele,\n                    <jats:italic>badh2.1</jats:italic>\n                    , is the predominant allele in virtually all fragrant rice varieties today, including the widely recognized Basmati and Jasmine types. Haplotype analysis allowed us to establish a single origin of the\n                    <jats:italic>badh2.1</jats:italic>\n                    allele within the\n                    <jats:italic>Japonica</jats:italic>\n                    varietal group and demonstrate the introgression of this allele from\n                    <jats:italic>Japonica</jats:italic>\n                    to\n                    <jats:italic>Indica</jats:italic>\n                    . Basmati-like accessions were nearly identical to the ancestral\n                    <jats:italic>Japonica</jats:italic>\n                    haplotype across a 5.3-Mb region flanking\n                    <jats:italic>BADH2</jats:italic>\n                    regardless of their fragrance phenotype, demonstrating a close evolutionary relationship between Basmati varieties and the\n                    <jats:italic>Japonica</jats:italic>\n                    gene pool.
