Eighteen JWC rice lines were crossed with 2 contrasting CMS lines derived from Hong Lian (HL) and wild abortive (WA) CMS sources, and the F1s evaluated for pollen and spikelet fertility at Nanjing during 1990-91. Seven of the JWC lines were efficient restorers for both HL and WA lines and could be used to develop indica/japonica intersubspecific hybrids. A further 7 JWCs were good maintainers for both CMS lines and could also be used as backcrossing parents to develop CMS lines with wide compatibility.
