^amap coverage in genetic and physical maps was based on the reference of Nipponbare/Kasalath map (Harushima et al.[1998]) and IRGSP build5 (http://www.rgp.dna.affrc.go.jp/), respectively.
ID = F₂ of Ilpumbyeo x Dasanbyeo; DI = F₂ of Dasanbyeo x Ilpumbyeo.
ID//D = Ilpumbyeo/Dasanbyeo//Dasanbyeo, ID//I = lpumbyeo/Dasanbyeo//Ilpumbyeo.
DI//D = Dasanbyeo/Ilpumbyeo//Dasanbyeo,DI//I = Dasanbyeo/Ilpumbyeo//Ilpumbyeo.
I//ID = Ilpumbyeo//Ilpumbyeo/Dasanbyeo; I//DI = Ilpumbyeo//Dasanbyeo//Ilpumbyeo.
D//ID = Dasanbyeo//Ilpumbyeo/Dasanbyeo; and D//DI = Dasanbyeo//Dasanbyeo/Ilpumbyeo.
