Rupestris x Lincecumii. Rupestris x Cinerea; Cinerea controls the vine and fruit. 



Rupestris x Berlandieri. Rupestris x Monticola. 



Rupestris x Rotundifolia, Incongenial. 



Longii x Lincecumii. Longii x Candicans. 



Longii x Labrusca; Longii controls vine, Labrusca the fruit. 



Vulpina x Longii. Vulpina x Candicans. 



Vulpina x Labrusca; Vulpina controls the vine, Labrusca the fruit. 



Vulpina x Bicolor. Vulpina x Cinerea. 



Vulpina x Vinifera; Vulpina controls the vine, Vinifera the fruit. 



Girdiana x Vinifera. 



Champini x Labrusca; Champini controls the vine, Labrusca the fruit. 



Champini x (Labrusca x Vinifera) ; the hybrid controls fruit. 



Candicans x Rupestris; Candicans controls vine, and fruit. 



Labrusca x Vinifera; Labrusca controls vine, Vinifera the fruit. 



Labrusca x Vulpina. Equalize well in most cases. 



Bourquiniana (Herbemont) x Labrusca (Martha). 



Bourquiniana (Herbemont) x ^Estivalis (Norton). 



Bourquiniana (Herbemont) x Triumph ; Herbemont controls vine, Triumph the fruit. 



Lincecumii x Rupestris, Lincecumii x Labrusca; Lincecumii controls vine, Labrusca the 

 fruit. 



Lincecumii x Candicans. 



Lincecumii x Cordifolia. 



Lincecumii x Herbemont; Lincecumii controls vine, Herbemont the fruit. 



(Lincecumii x Herbemont) x Vinifera. In these Vinifera appeared to control vine in botani- 

 cal markings, but Herbemont and Lincecumii in vigor and fruit. Several such hybrids 

 were quite uniform. ^Estivalis (Norton) x Labrusca (Concord), the union quite even. 



Cinerea x Cordifolia. Berlandieri x Monticola. 



Monticola x Rupestris. Monticola x (Lincecumii x Catawba) Fern. 



Berlandieri x Champini. Berlandieri x Fern. 



Berlandieri x Vinifera (Quagliano). Generally equalize well. 



Rubra x Herbemont. 



Rotundifolia (Scuppernong) x Post-Oak Grape hybrid. Rotundifolia is very persistent in 

 impressing its character upon its hybrid progeny, both in vine and fruit, even to the 

 second generation. 



Rotundifolia x Munsoniana. 



Generally, the more distinct and uniform a species the more prepotent it is over less distinct 

 and less uniform species. In conformity to this the more complex a hybrid is the less it shows 

 of itself in combination with a pure variety of a pure species. This should be expected as a 

 corollary of Mendel's law of heredity. 



Also in conformity to this law, the more complex a hybrid is, the more variable among 

 themselves are its pure seedlings. 



We may expect the male parent to more often control in appearance and quality in fruit, 

 and the female in vine; yet, if we designate it a general law, there will be found many exceptions. 



Field of Development 



When we view the development, both natural and artificial, arrived at, and then reflect and 

 compare the small cymose cluster and minute, skinny, seedy, pungent fruit of the Virginia Creeper 

 (Ampelopsis quinquefolia) with the larger clustered, but scarcely larger berried, skinny, seedy, 

 pungent, Frost Grape (V. Cordifolia} we can notice a decided advance in quality. When we com- 

 pare the Frost Grape with the Fox Grape (V. labruscd), the Southern Muscadine (V. rotundi-
