I collected seeds from all over the world and grew them in a large field and took images of the heads.
I also did a form of DNA sequencing, and used that data to estimate which population they are members of (each color of the vertical bar represents a single population).
Tools: the image is made in R.
The population structure (vertical bars) are made with ~ 10 K genetic markers using a lot of different bioinformatics tools (TASSEL, fastSTRUCTURE, R).
edits/comments:
I thought they all tasted delicious; I didn't have a clear favorite, although I did think the orange group (the Spigarello types) was quite interesting from a flavor perspective. The colored bars are made with ~10K molecular markers (SNPs). Varieties that share a given color tend are more closely related. This type of analysis can help understand the domestication and selective breeding that broccoli has undergone over time A lot of the questions here are addressed in some of my other work: how does the heading phenotype change using a cross between a Chinese kale and a broccoli and a similar analysis looking at a slightly wider range of brassicas
edit 2: Thanks for chatting with me, y'all. It warms my cold heart that there's so much interest in the wacky world of Brassicas. Also, whom'st'evr gave me those those cool reddit things, thank you!

Were you able to also examine their taste/mouth feel/culinary applications? This is such a cool chart

Broccoli is a fascinating plant.
Brassica oleracea.
It's technically the same plant as cabbage, and cauliflower, and Brussels sprouts, and Kale, and collard greens.
It's basically the dog of the plant world. It's the same way that a poodle is sort of a wolf...
