Brassica oils species production

In the spring of 1942, Dr. Stevenson supplied a few federal experimental farms and stations with the small quantity of seed he had on hand. The harvest of that year amounted to 2600 pounds (52 bushels) of seed of Brassi-ca napus species. A considerably larger quantity of seed than this was required for planting in 1943 to relieve the serious shortage of rapeseed oil. Dr. Stevenson located and purchased a total of 41,000 pounds from U.S. seed companies. This seed had originally been secured from Argentina and the name Argentine for the Brassica napus was widely used in the early years of production, and still is applied to the varieties of the Brassica napus species.

The goitrogenic brassica factors from various species of cabbage (Brassica) seem to inhibit uptake of iodine by the thyroid. The inhibition has been attributed to SCNe, which appears as one of the hydrolysis products of mustard oil glycosides, such as glucobrassicin (3). 

The consuming public is frequently unaware of the dietetic importance of Brassica oilseed crops since their oil and meal products are usually processed and blended as they enter the food chain. On the other hand, almost every consumer is familiar with their close relatives, the cole vegetables such as cabbage, cauliflower, broccoli, and Brussels sprouts, the condiment mustards, and the root crops of turnips, rutabagas and radishes. Many farmers directly feed forage rapes and kales while others attempt to rid their fields of weedy species such as black and wild mustard.
