About Oryza sativa (Xian/Indica-3B1 var. Khao Yai Guang)

Asian cultivated rice is a staple food for half of the world population. With a genome size of ~390 Mb (n=12), rice has the smallest genome among the domesticated cereals, making it particularly amenable to genomic studies. In 2020, a reanalysis of the population structure analysis showed that rice could be subdivided into a total of 15 subpopulations (XI-1A, XI-1B1, XI-1B2, XI-2B, XI-2A, XI-3B1, XI-3A, XI-3B2, GJ-trop1, GJ-trop2, GJ-subtrp, GJ-tmp, cA2, cA1 and cB) and 4 admixed populations (GJ-adm, XI-adm, admixed and cA-adm). Then 16 rice cultivar varieties were selected based on genetic diversity and origin that could represent the 15 subpopulations and the largest admixed population, i.e. XI-adm. The collection of 16 Platinum Standard RefSeqs (PSRefSeq) can be used as a template to detect virtually all standing natural variation that exists in the pan-genome of cultivated Asian rice. Oryza sativa cv. IRGC 127518 (variety cv. KHAO_YAI_GUANG::IRGC_65972-1) (collected from: Thailand) is selected as the representative of XI-3B1 subpopulation, in which the accessions are mostly collected from Thailand, Lao_People_s_Democratic_Republic, and Cambodia.

Notes of Subpopulations: cA = circum-Aus; cB = circum-Basmati; GJ= Geng-japonica where trop = tropical, subtrp = subtropical; XI = Xian-indica
