Table 2 Substitution of O. rufipogon segments in CSSLs and cumulative proportion of donor genome represented by homozygous and heterozygous segments

From: Development and characterization of chromosome segment substitution lines derived from Oryza rufipogon in the genetic background of O. sativa spp. indica cultivar 9311
