Sequence polymorphism in Wx locus of 22 Bangladeshi rice landraces was analyzed.
Most of the Bangladeshi landraces showed SNP patterns reported in South & Southeast Asian varieties.
Three Beruin cultivars lacked the known glutinous alleles but had waxy or low amylose.
Novel Wx promoter/intronic mutations in these 3 Beruin cultivars may explain their glutinous phenotype.
