I think a lot of numbers and names of varieties are localized. I used to seed lawns and in the trade magazines I have read of grass varieties that I had never heard of and when I called these companies " oh that wont grow in Delaware" . So now I sell Delkab seed corn and check in the national pamphlets and see varieties that we dont even sell in this area, I never grew oats, but for winter feed try rye or wheat, see how that works for you....
