AI Article Synopsis
- - CSSLs, or chromosome segment substitution lines, are valuable genetic resources for breeding and finding new agricultural traits in rice by using wild relatives as genetic sources
- - The study developed 26 CSSLs that span the entire genome of a wild rice relative, which was crossed with the popular rice cultivar Koshihikari
- - Evaluation showed that these CSSLs contain candidate segments linked to important traits, suggesting that the wild relative could provide novel alleles to enhance the Koshihikari variety's yield and related characteristics
Article 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. is a wild relative of rice that is thought to be a progenitor of spp. . In the present study, 26 CSSLs that covers the entire genome of as contiguous, overlapping segments in the genomic background of a cultivar, 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 as a source of novel alleles that can be used to improve the existing cultivar.
