Schematic of the development of the reciprocal chromosome segment substitution lines (CSSLs) between Koshihikari and Takanari. CSSLs carrying a Takanari chromosomal segment in the Koshihikari genetic background (A) and a Koshihikari chromosomal segment in the Takanari genetic background (B). The numerator and denominator in parentheses indicate the number of plants selected and the number investigated by marker-assisted selection (MAS), respectively. A total of 4432 and 4406 plants were used for the development of CSSLs in the Koshihikari and Takanari backgrounds, respectively.
