Populations detected in the indica subpanel. Accessions belonging to the same population are in the same color; in brackets, the number of accessions of the population; admixed are in black; the indica check (IR64) is in pink. The main characteristics of the populations, separated by a semi-column, are given in the following order: − Zone of origin: MRD = Mekong River Delta; SE = Southeast; CH = Central Highlands; SCC = South Central Coast; NCC = North Central Coast; RRD = Red River Delta; NW = Northwest; NE = Northeast - Ecosystem: IR = irrigated; RL = rainfed lowland; UP = upland; MX = mixture of types - Maturity class: E = early; M = medium; L = late; VL = very late - Grain length to width ratio: A = L/W > 3.0; B = 2.5 < L/W < =3.0; C = L/W < =2.5 - Grain type: G = glutinous; NG = non-glutinous.
