JH and HN refer to Jinghong Station in Yunnan and Hainan Station in Sanya, Hainan, China. FS, first (that is, hot and dry) season; WC or WS, second (that is cool and wet) season in double-crop regions. Red font indicates the different generations. SP1 is Oryza sativa spp. indica RD23 (P1), SP2 is O. longistaminata (P2), and SP3 is RD23 / O. longistaminata (F1). SP4 to SP11 are single individuals selected from the previous generation, with both good fertility and good rhizome characteristics. Yellow boxes indicate O. sativa, purple box indicates O. longistaminata, blue boxes indicate interspecific breeding lines, and orange boxes indicate interspecific cultivars. The numbers of plants evaluated in each generation from F1 to F15 were 1, 1, 1, 7,200, 1,250, 57, 78, 104, 384, 864, 100, 1,078, 1,294, 1,572, 1,403, 1,520 and 1,105, respectively.
