Identification of the Azucena aroma allele badh2 and sequence alignment of BADH2 alleles in different rice varieties harbouring aroma haplotypes. The 12 bp sequence variation identified in the badh2 Azucena aroma allele is identical to that identified in Basmati and Jasmine rice aroma gene candidates. Nipponbare and 93-11 displayed no sequence variation, showing that they only contain the no-aromatic allele badh2. Four varieties not classified as aromatic (Arias, JC120, Khao Kap Xang, JC157) show the 12 bp mutation in BAD (Table 5)
