| grhrtn, mustard is in the large Brassica family. I don't know what it will easily cross with, but the family includes broccoli, cauliflower, brussels sprouts, kale, radish, and cabbage. It won't breed easily, but there is even an effort at the University of Idaho to cross mustard with canola to get mustard's good growing characteristics with a higher quality oil. |

| As far as pumpkins and squash this is a site that I found when wondering what I can cross some Atlantic Giants with. They are C.Maxima, but as you can see at the end of the report it shows the species and cultivar. I am not a geneticist, but I believe you can cross plants in the same species. So take a look and see. Look to the end of the article as it is a bit drawn out for your purposes. http://www.ars-grin.gov/npgs/cgc_reports/squash95.pdf |
