Some F x Hybrids

teristic of all Rotundifolia-Euvitis hybrids, and any vine 'that is claimed 
to be a hybrid but which is normally fruitful must in the light of our 
experiments be regarded as of nonhybrid origin. 
Fruit-clusters: Small to very small in Rotundifolia and still smaller 
in the hybrid because of sterility due to hybridization. (See Fig. 21.) 
Berries: Roughly speaking, the berries might be said to be of an 
intermediate character in the hybrid. 
Seeds: The seeds of Rotundifolia are oval in general outline, the 
ventral sutures, extreme ends excepted, are generally parallel to each 
other. The seeds of the hybrid inherit the same general shape as is 
found in the Rotundifolia parent but the ventral sutures and some 
minor markings appear more like similar markings found in Euvitis. 
The size of the seed seems to be intermediate. (See Figs. 8 and 22.) 
From the general comparisons drawn between our true hybrids 
and their supposed dominant parent species, Yitis rotundifolia, whose 
description should correspond with that of the so-called “false hybrids” 
we can safely conclude that the so-called “false hybrids” are no hybrids 
at all but simply straight seedlings of Yitis rotundifolia. 
CON CLU SION S 
Turning now to the previously reported “false hybrids” we shall 
endeavor to show why these should not be considered as hybrids with 
Euvitis but as seedlings of the Muscadine group. 
Professor Millardet reported all of his vines as “false hybrids.” This 
information is gathered from a statement made by Dr. T. Y. Munson, 
who had considerable correspondence with Professor Millardet. This 
statement taken from Munson’s Foundation of American Grape Cul¬ 
ture and found on page 208, reads as follows: 
“The writer (Dr. Munson) had noted what Professor Millardet had 
written him about “false hybrids” including all his Scuppernong 
hybrids as such; that while they were actual hand-made hybrids, yet 
the Rotundifolia was so firmly fixed that its characteristics were the 
chief to show forth in the hybrid, those of the other parent being 
‘recessive’ according to Mendel’s characterization.” 
The vines of Professor Millardet were lost but this short, general but 
definite description of them seems, in the light of our investigations 
with hybrid material, sufficient to stamp them indelibly as being pure 
seedlings of the Muscadine group and not as hybrids, as their originator 
supposed them to be. 
The varieties LaSalle and San Jacinto originated and disseminated 
by the late Dr. T. Y. Munson at Denison, Texas, which are claimed to 
be hybrids between Scuppernong (female) and some Post-Oak X Herbe- 
mont hybrids (male) ; and his other similar varieties, Sanalba, Sanme- 
laska, Labama, Sanmonta and San Rubra, which are similarly claimed 
to be hybrids between the variety San Jacinto (female) and Brilliant
