ters were cross-pollinated with 1-1 and eight similar clusters were cross- 
pollinated with G-52. From these covered and cross-pollinated clusters 
93 and 143 seeds respectively were obtained. 
Because of limited available space in the nursery in 1918, only 14 true 
hybrids of the Malaga x G-52 cross were retained and none of the seed¬ 
lings of the Malaga x 1-1 cross were planted. 
Vitis Rot undifolia X Vitis Vinifera 
In 1917 one flower cluster on the forced Scuppernong vine in the 
greenhouse was bagged and cross-pollinated with pollen from Malaga. 
Ho fruit developed. 
The same year W-38, a seedling of Scuppernong x Dark Male Ho. 1, 
was used as the female parent and Malaga was used as the male parent. 
Seven flower clusters on W-38 were bagged and pollinated with fresh 
pollen from the Malaga vine. One fruit developed from this work, but 
not as the result of hybridization. 
Five flower clusters on G-12, an imperfect hermaphroditic seedling of 
Thomas x Hope, were bagged and pollinated with Malaga pollen. Ho 
fruit resulted. 
Five flower clusters on the Flowers vine were bagged and pollinated 
with Malaga pollen. Ho fruit developed from this work. 
Ten flower clusters on the Oberlin vine, a Rotundifolia variety orig¬ 
inally found growing wild in Oberlin and only about one mile from the 
college campus, were bagged and pollinated with Malaga pollen. From 
this work three berries developed and ripened, from which five seeds were 
secured. These seeds were planted and in 1918 two true hybrid vines 
were obtained. These two vines are still growing and will be more fully 
discussed in our succeeding bulletin. 
In 1918 ten flower clusters on the Oberlin vine were again bagged 
and pollinated with Malaga pollen, but no fruit developed from this 
work. 
From the results of the preceding efforts we find that the reciprocal 
cross, Yitis rotundifolia x Vitis vinifera, although difficult to obtain 
can be effected. Dearing (5) finds certain varieties of both species more 
congenial to hybridization than others. 
Vitis Labrusca X Vitis Rotundifolia 
In 1917 ten flower clusters on a Concord vine (Y. labrusca) were pre¬ 
pared, bagged and pollinated with pollen from G-52. In the fall of the 
year 130 seeds were obtained and planted. From this lot of seeds 12 
true hybrid seedlings were observed to grow; others may have germi¬ 
nated but were not recognized as such before their death. Only five of 
the hybrids were strong enough to be transferred to the nursery. 
Ten flower clusters on a native imperfect hermaphroditic vine (Y.
