Abstract |
Chromosome segment substitution lines (CSSLs) are rich genetic resources that can be mined for novel, agriculturally useful loci or that can be used directly as materials for breeding. To date, a number of rice CSSLs have been developed by crossing rice cultivars with its wild relatives as a means to tap into the potential of wild alleles in rice improvement. Oryza nivara is a wild relative of rice that is thought to be a progenitor of O. sativa spp. indica. In the present study, 26 CSSLs that covers the entire genome of O. nivara as contiguous, overlapping segments in the genomic background of a japonica cultivar, O. sativa cv. Koshihikari were developed. Evaluation of the CSSLs for several agriculturally important traits identified candidate chromosome segments that harbors QTLs associated with yield and yield-related traits. The results of the study revealed the potential of O. nivara as a source of novel alleles that can be used to improve the existing japonica cultivar.
