Hybridization With Other Species of G-rapes. 
While excellent results may be obtained from careful breeding work 
within this species, it is possible that the greatest improvement will 
come from the crossing of this with other species of grapes. It may 
be necessary to hybridize it with other species to obtain uniformity of 
ripening, large clusters, and better clinging propensities. 
We have done a limited amount of work in attempting to cross the 
Scuppernong with other species, with the following results: 
Work Done in 1911. 
Scuppernong flowers were treated with pollen from Yitis aestivalis. 
In this work five large canes, with many flower clusters, were covered 
with bags; and as the blossoms opened from time to time they were 
carefully hand pollinated. Ho fruits developed from these blossoms, 
hence no seeds were obtained. 
In similar manner, Scuppernong flowers that were treated with pollen 
from Niagara (F. labrusca ) produced no fruits. 
Scuppernong flowers treated with pollen from male plants of F. 
cinerea produced no fruits. 
Scuppernong flowers treated with pollen from Herbemont (F. aesti¬ 
valis bourquiniana) produced one berry with four seeds. From these 
four seeds two plants were secured, but one of which is alive. 
Work Done in 1912. 
I 
Five bunches of the Scuppernong were bagged, and the flowers were 
treated with pollen from V. aestivalis. 
Five bunches of the Scuppernong were bagged, and the flowers were 
treated with pollen from Herbemont. 
Five bunches of Scuppernong were bagged and the flowers were 
treated with pollen from Winchell (F. labrusca ). 
Results of this work—Hone of these combinations produced any 
fruits. 
These results seem to indicate that such combinations are not very 
congenial, and if successful at all, proceed only with considerable 
difficulty.
