Chromosome segment substitution lines （CSSLs）, a powerful tools for identifying favorable alleles in unadapted germplasm, is being widely used. In this study, the authors developed a set of CSSL population consisting of 53 lines which were derived from the recipient Xiushui 134 and the dono Yangdao 6. The CSSL length of substitution segments ranged from 7.4 to 182.15 cM, it accounted averagely for 5.0% （from 0.49% to 12.15%） of whole rice genome. The total length of substitution segments including 12 chromosomes was 1 995 cM, which was 1.33 times as long as the whole rice genome. In conclusion, strategy for developing CSSL and its application were discussed.
