Breeding Rotundifolia Grapes

Thickness of Skin. 
The following table shows that a very large percentage of the hybrids 
produce fruit with thick or with very thick skin. The Scuppernong 
hybrids include 392 with thick skin, and 117 with very thick skin; 
and only 66 with thinner skin than the Scuppernong. James has a 
very strong tendency to transmit a very thick skin to it’s offspring. 
Out of a total of 52 fruiting vines, with James as one of the parents, 
only two were observed that produced fruits with a thinner skin than 
its parent. The results of the Thomas seedlings are surprising, for 
every one of it s hybrids has a thicker skin than the parent.

Character of the Pulp of the Hybrid Seedlings. 
The pulp or flesh of all of our cultivated varieties of rotundifolia 
grapes is greatly in need of improvement. The pulp of most of the 
varieties is soft and stringy, while of others it is rather tough. Tor 
shipping purposes we need varieties with firm, meaty, but tender pulp. 
That such varieties can be produced is indicated by the following table:

The vast majority of the hybrids are similar to the parents in the 
character of pulp. With the exception of the hybrids of Scuppernong, 
crossed with Light Male 'No. 1, which includes only a small number 
of vines, all of the crosses produced some vines that produce rather 
firm flesh.
