Some F 1 Hybrids 
39 
The average fruit-cluster, judging from the few that were produced, 
is smaller than that of either parent hut in character more nearly 
approaching that of Rotundifolia. 
The berries are hybrid in character, but the character of the pulp 
and the sweetness seems to tend toward the Euvitis parent. 
The seeds from general appearances are typically Rotundifolia 
although the colors of the beak, sutures and body of the seed as well as 
the character of the sutures disclose the true hybrid nature of the seed. 
After having made these comparisons, we learn that in the F x genera¬ 
tion Yitis rotundifolia is not as dominant in character as it is generally 
supposed to be; that the hybrid vines are not characteristically Rotundi¬ 
folia in type but more or less intermediate. 
Munson (2), speaking about grapes in general, says, “In some com¬ 
binations, all the characters of one parent are dominant and, of course, 
all others recessive. This is true of Yitis rotundifolia (as female) 
when united with varieties of true bunch grapes, the Rotundifolia 
character being dominant.” In the same article he endeavors to estab¬ 
lish a law governing the characters in the Fi generation when a species 
of Yitis with variable characters is mated with another species the 
characters of which are very uniform. 
The law laid down by Munson reads thus, “Species of grapes very 
uniform in character when hybridized with species of very variable 
character give progeny with the characteristics of the uniform species 
dominant.” These conclusions drawn by Munson and based on his 
so-called “false hybrids” when compared with the results of similar 
work done at the North Carolina Experiment Station must be con¬ 
sidered as incorrect. 
D. SO-CALLED “FALSE HYBRIDS” 
“False hybrids” defined: “False hybrid” is a term that has been 
repeatedly used by some early Rotundifolia grape breeders and may be 
defined thus: a hybrid whose chief visible characteristics have been 
imparted to it by one of the parents only and all or practically all of 
whose recessive characteristics have been imparted to it by the other 
parent. 
Theoretically such a hybrid may be possible, several have been 
reported, but on critical examination these usually turn out to be noth¬ 
ing more than straight seedlings from one of the parent species. 
“False hybrids” have been reported by Professor A. Millardet of 
France (1), by T. Y. Munson of Denison, Texas (1) and Dearing (3) 
reports “One supposed hybrid was secured, a cross of Eden (female) 
and Flame Tokay (male).” This supposed hybrid from its descrip¬ 
tion, meager as it is, can very easily be placed alongside the “false 
hybrids” of Millardet and Munson.
