Paternal chromosome elimination of inducer triggers induction of double haploids in .

A synthetic octoploid rapeseed, Y3380, induces maternal doubled haploids when used as a pollen donor to pollinate plant. However, the mechanism underlying doubled haploid formation remains elusive. We speculated that double haploid induction occurs as the inducer line's chromosomes pass to the maternal egg cell, and the zygote is formed through fertilization.

Rapid Creation of Interspecific Hybrid Progeny to Broaden Genetic Distance through Double Haploid (DH) Inducer in .

Interspecific hybridization of rapeseed is an important way to innovate breeding resources. This research used and for artificial synthesis interspecific hybridization of F. The F self-fruiting rate was particularly low.
