234 THE CHIEF SOUTHERN AGRICULTURAL CROPS 



the delicious but unfortunately rather delicate kinds 

 produced by combinations of the vinifera and 

 Labrusca tj'pes, while the achievement of T. V. 

 Munson of Texas in producing an entirely new 

 race of grapes, better adapted than any of the 

 old ones to southwestern conditions, by using the 

 native post- oak grape of Texas as the foundation for 

 his crosses, is one of the most notable in the entire 

 history of plant breeding. A wild grape ( Vitis 

 Carahcea) grows abundantly in many parts of the 

 West Indies. It is exceedingly vigorous and the fruit 

 is of fair quality. It could doubtless be used with 

 equal success as the basis for a race of grapes entirely 

 adapted to tropical conditions. 



The vinifera or European kinds are practically 

 the only ones grown in Europe and in California. 

 All of the raisin grapes and many of the best 

 wine and table grapes belong here. They require 

 a warm, dry climate in order to succeed well, and 

 unfortunately none of them are fully successful at 

 the South. In a humid climate they are very 

 subject to mildew and to other diseases, and every- 

 wdiere they are exceedingly susceptible to the at- 

 tacks of Phjdloxera. 



The Labrusca varieties are the ones most generally 

 grown in the northeastern United States, and they 

 include such well-known kinds as Concord, Ca- 

 tawba, and Niagara. They can be grown as far 

 south as the Gulf coast, but are not fully successful 

 in peninsular Florida and are probably not adapted 

 to tropical conditions. They are good growers and 

 are comparatively resistant to most grape disease.
