The future of crop improvement depends on the availability of genetic variation. There is a larger pool of genetic variation available in landraces and wild relatives of crops. To take advantage of the unexploited reservoir that exists in these wild relatives of cultivated rice (Oryza sativa L.), we have developed interspecific introgression lines that will be of immediate use to breeders and will simultaneously serve to enhance our understanding of the “wild alleles” that contribute favorably to plant performance under drought stress. These lines are called Introgression Lines or Chromosome Segment Substitution Lines (CSSLs).
