Breeding plants with genes from one parent (phys.org)

I feel like there is some missing context in this article. I worked at <mega ag corp> in molecular breeding for ~3 years, starting in 2007 or 2008. And we were already using colchicine to created doubled haploids (read: pure inbred plants in one generation instead of like, 8 generations). So that had been a thing for awhile by 2010. I think what the article is trying to discuss is the ability to create doubled haploids using this other approach (the altered centromere). This is presumably preferred because colchicine is a nasty carcinogen and we wouldn't let pregnant women or women who wanted to get pregnant anywhere near it as it could cause birth defects. Granted, this was 10+ years ago, and I didn't work directly in the lab, but creating software to design their experiments and analyze the results.
