oducing well. We
consider this species as good or nearly as good as shagbark as a stock.

We have received contrary reports from farther south. These may be due
to stock being blamed for something they did not cause or it may be that
bitternut stocks grown from seed of more southern origin may not be as
good as our northern stock.[18]

PECAN (_Carya pecan_). Our experience with this species as a stock is
very limited and has been confined to grafts of only one variety of
shagbark (Wilcox). Results were very disappointing, but we have been
told by others that it makes a good stock. It is much faster growing
than is shagbark.

Walnut

In walnut grafting, we have found that the eastern black walnut
stocks are so much superior to any others we have been able to find,
that we have discarded all others.

BUTTERNUT (_Juglans cinerea_). We have found that it is much harder to
secure living grafts on this stock than on black walnut. It also
attracts butternut curculio to the nursery.

JAPANESE WALNUT (_Juglans sieboldiana_ and variety _cordiformis_). We
have found that seedlings grown from either of these species are a great
attraction to the butternut curculio. They are more difficult to secure
living grafts on, and grafts on these stocks are very definitely less
hardy than similar grafts on black walnut growing side by side. We have
proved this repeatedly.

PERSIAN WALNUT (_Juglans regia_). We have never used this species as a
stock, and in view of the fact that grafts of it grow so well on black
walnut stocks, I can see no use in even trying it.

EASTERN BLACK WALNUT (_Juglans nigra_). As stated above, we have found
this to be the ideal stock for all walnut grafting. It is more free from
insects than any of the other walnuts. Grafts grow well on it and are
more hardy than grafts on some of the others.

We have not had enough experience in grafting chestnuts and filberts
even to offer any comment as to stocks for them.

seed source. At any rate, the poorest growing pecan in the University of
Illinois orchard is on a Wisconsin bitternut understock.--J. C. McD.]
