Fig. 1.

Unrooted neighbour-joining tree showing genetic relationships between the 107 rice accessions and four controls based on 376 SNP markers. The four major groups of Oryza sativa are labelled in bold italics: japonica (Nipponbare as reference), aromatic (Basmati 370 as reference), indica (93-11) and aus (N22 as comparison line). A sub-cluster of Pokkali accessions are shown within the indica group. The Pokkali × IR29-derived RIL FL478 is located near IR29. Most of the salt-tolerant landraces from Bangladesh are within the different indica sub-clusters, apart from the Pokkali accessions.
