Combinations Suggested for Breeding Work. 
To those who wish to take up breeding work with this species and 
wish to give attention to color, we wish to suggest the following com¬ 
binations : 
For new white varieties: 
Scuppernong X Light Males. 
James X Light Males. 
Memory X Light Males. 
Latham X Light Males. 
Smith X Light Males. 
Only about one-half of the fruiting seedlings resulting from each 
of the last four combinations suggested will produce white fruit. 
For new black varieties: 
Scuppempng X Pure Dark Male. 
James X Pure Dark Male. 
Flowers X Pure Dark Male. 
Memory X Pure Dark Male. 
For new red varieties: 
Thomas X Light Male. 
Scuppernong X Dark Males Heterozygous for red and black. 
Latham, heterozygous for red and white, X Light Male. 
Size of the Flower Clusters of the Hybrids. 
Attention has been called to the fact that the fruit clusters of these 
varieties are too small for present market requirements. One of the 
first and most important improvements to be made is an increase in 
size of the flower cluster and consequently the fruit cluster. That 
the flower cluster can be increased in size is shown by the data presented 
herewith. This data is confined to three varieties.

It will be noted that where the Scuppernong was crossed with a male 
vine having small flower clusters that none of the hybrids produced 
flower clusters above medium size. Where this same variety was 
crossed with a male having large sized flower clusters only three, or
