a) Unrooted neighbour-joining tree and b) an UPGMA (unweighted pair group method with arithmetic mean) cluster dendrogram showing genetic relationships between the four proposed lines (IR83484-3-B-7-1-1-1: BRRI dhan97, BR9011-67-4-1: BRRI dhan98, HHZ5-DT20-DT2-DT1: BRRI dhan99, HHZ12-SAL2-Y3-Y2 and three check varieties (BR26, BRRI dhan28, and BRRI dhan67) based on the 1K Rice Custom Amplicon assay or 1k-RiCA SNP markers. All four lines and three checks showed distinct molecular variations/differences among them. (PDF)</p

The illustrative view of grain quality properties of the studied new and check varieties.

The breeding lines IR83484-3-B-7-1-1-1 (BRRI dhan97), HHZ5-DT20-DT2-DT1 (BRRI dhan99); the checks BRRI dhan67, and BRRI dhan28 are displayed in the figure as paddy, parboiled, unparboiled, and cooked rice, respectively. Parboiled rice indicates partially boiling the rice within its husk, whereas unparboiled rice was dehusked without boiling.</p
