Limits in Hybridization

3. Work of Professor A. Millardet, France, Subsequent to 1877. 
All we can learn of the work of Prof. A. Millardet on the hybridi¬ 
zation of the Rotundifolia grape is that he never was successful in its 
hybridization. He produced a lot of seedling vines which he fully be¬ 
lieved were true hybrids but which we shall later learn were apparently 
only direct descendants of AAtis rotundifolia. 
4. Work of Dr. T. V. Munson, Denison, Texas, 1890-1900. 
In 1891 Dr. T. V. Munson saved seed from fruits of a Scuppernong 
vine Avhich he presumed to have been pollinated and fertilized with 
pollen from some near-by Post-Oak x Herbemont hybrid vines. From 
the resulting seedlings of this lot he saved some 50 vines which he con¬ 
sidered as hybrids, for a trial in his nursery. From these 50 seedlings 
he finally selected two which he named La Salle and San Jacinto and 
these he propagated and disseminated as his first hybrid varieties. 
In 1898 Dr. Munson covered some flower clusters on the San Jacinto 
vine with tissue paper bags and pollinated these with pollen from Bril¬ 
liant, which is a Labrusca-Vinifera-Bourquiniana hybrid. From the 
seeds produced by these clusters he grew some 200 plants from which he 
selected 85 for trial in his nursery. From these he finally selected four 
vines for propagation and dissemination and named them Sanalba, 
Sanmelaska, Sanamonta and Sanrubra. 
Dr. Munson also made a number of hybrids between Yitis rotundi¬ 
folia and Yitis munsoniana, chief among which is the DeSoto. 
With the exception of the last one, one vine of each of the above 
named varieties was secured by the North Carolina Experiment Station 
in January, 1909, and these plants have since that time been constantly 
under observation. After a time, the observations made gave rise to 
some doubt as to their real hybrid origin, and more recently to a very 
careful comparison of these vines with known hybrid material produced 
in the breeding plots at this Station. These comparisons together with 
conclusions drawn from them will appear in a separate bulletin which 
will follow immediately. 
Although we regret it very much, suffice it to say here that while Dr. 
Munson firmly believed he had produced hybrids between Y. rotundi¬ 
folia and species of Euvitis and disseminated his choicest selected vines 
as such, these vines are not true hybrids but only seedling vines directly 
descended from the Muscadinia group. 
5. Work of the North Carolina Agricultural Experiment Station 
1911 and 1912. 
The North Carolina Agricultural Experiment Station began (4) its 
work in the hybridization of Yitis rotundifolia with related species in 
the spring of 1911. During this season, all of the work was confined to
