WebJan 1, 2024 · A Chromosome Segment Substitution Line (CSSL) is a type of backcross that is coupled with Marker Assisted Selection (MAS) and selfing to generate an isogenic line or near isogenic line that carries a chromosome or segment of a chromosome from the donor parent within the genetic background of the recurrent parent. WebApr 8, 2024 · Doubled haploid (DH) lines contain two identical sets of chromosomes in their cells. They are completely homozygous, as only one allele is available for all the genes. Usually, DH lines are produced from haploid lines (Fig. 3.1 ). These haploid lines either occur spontaneously (e.g., rapeseed and maize) or can be induced artificially.
