Additional file 8 of Maternal karyogene and cytoplasmic genotype affect the induction efficiency of doubled haploid inducer in Brassica napus

Additional file 8. Test material information. The same number of materials used represents the same karyogene, “A” represents sterile line, “B” represents maintainer line, pol CMS was bred by backcross with 15 generations of maintainer line, and ogu CMS was bred by backcross with 12 generations of the same maintainer line, only cytoplasmic genotype differences, but 0068 and 0933 have similar sources. The collection and breeding of the Brassica napus materials we use has obtained local permits in China, which is in line with national policies. The Brassica napus used in this study is commonly grown oil crop used species native to China and does not fall under the Nagoya protocol.
