18 Promising Varieties 



In 1921-1922 all grapes were carefully pruned arid put on wires, 

 the two-wire Kniffin system being used. All of the pre- 

 vious year's growth was carefully measured and recorded in order 

 to make a careful comparative stud}' of their habits of growth. 

 The growth up to August 1, 1922 was again studied, and the results 

 of these two studies appear in the first list under vitality. 

 The strongest growers are marked R ''rampant), Those pro- 

 ducing more than one hundred feet of new wood arc marked S 

 (strong growers) provided they did not show weak growth in 

 1922. Those making less than one hundred feet of new wood 

 but more than fifty fair are marked F (fair) while those making 

 still less growth are marked W (weak growers.) 

 In a few instances failure to make strong growth might possibly 

 be due to the ne.arness of rock formation under a vine, but as 

 in most instances there are five vines of each variety, and as the 

 average growth is taken in each case, the unfavorable location 

 of a single vine does not give any serious discrepancy. 



Late frosts in 1921 prevented many varieties fruiting at all, 

 but a carefully tabulated study of quality, quantity, and char- 

 acter of fruit borne by every vine that fruited was made. A 

 Similar study and record was made of these same varietiees in 

 the United States Government test vineyard at Arlington, Vir- 

 ginia, in August of the same year. 



In 1922 a similar careful study was made of the fruit in the 

 trial vineyard at Madison. A severe hail storm on August 3, 

 1922 destroyed a great part of the fruit, however, so it was im- 

 possible to get the exact weight of the fruit on the different vines. 



MOST PROMISING VARIETIES 



A list of the fifty most promising varieties is here given with 

 a record of their behavior. Those marked H fruit heavily. Those 

 marked M bear an average or moderate crop, while those marked 

 F have only made a fair yield. It is not deemed necessary to 

 list those that bore less than a fair crop. It must be understood 

 however that the vineyard is young and some varieties come 

 into bearing younger than others. On the other hand, the vine- 

 yard at Arlington, Virginia, is well established and should have 

 corrected any errors in the Madison vineyard.

* Since the above table was compiled all of these varities have been studied for two more 

 years .But there has been no reason to change the relative rating of any of them, all now 

 making an abundance of wood and are bearing well.
