Longistaminata Chromosome Segment Introduced Lines (LCSILs), in which chromosome segments from the African wild rice longistaminata were introduced into a cultivated rice variety, were genotyped using next-generation sequencers. Then, their blast resistance, salt tolerance, and cold tolerance were evaluated. The large variation in blast resistance among the lines was attributed to the introduction of chromosome segments of pLIA-1, the donor parent for the longistaminata genes. Positions of pLIA-1 chromosome substitution in the selected salt-tolerant lines did not match the known salt-tolerant QTL. The LCSILs were shown to be useful as breeding material for blast resistance and salt tolerance.
