982 VINE GROWING 



and the direct bearing hybrids are then classified as follows from different 

 points of view: 



I. — Classification of the Hybrids according to their Resistance 

 TO M11.DEW IN 1915 : 



A) Hybrids capable of dispensing with all spraying in normal years, 

 but which may receive one application to advantage, though such is not 

 indispensable in wet years: Couderc 7120 (the collection of which under 

 observation dispensed entirely with spraying even in 1910 and 1915), 

 132-11, 142-26, 162-5, 162-97 — Seibel 438, 793, 867, 4995. 



B) Hybrids which may be left unsprayed in normal years without 

 damage, though always receiving one application with benefit ajter flower- 

 ing, and which in wet years require 2 applications for complete preser- 

 vation: Berthille Seyve 450, 618, 822, 872, 1129 — Caille 16 — Che- 

 vallier 3401 — Castel 120, 315, 1028, 6239, 19422 — Couderc Baronne 2, 

 503, 28-112, 106-38, 106-46, 106-51, 162-46, 171-56, 202-75, 226-58, 235-120,

 2 — Peagei-i8 — Perbos N^ 1-46 and No 6-53 — Seibel 1,73,82, 84, 128, 138, 

 209, 844, 858, 880, 1000, 1077, 2006, 2007, 2052, 2658, 2660, 2666, 2709, 2806,

 4629, 4633, 4638, 4643, 4645, 4648, 4656, 4657, 4667, 4669, 4677, 4681, 4683, 

 4696, 4702, 4707, 4709, 4718, 4720, 4725, 4737, 4748, 4762, 4768, 4782, 4852, 

 4871, 4955, 4964, 4970, 4979, 4995, 5024, 5090, 5091. 



C) Hybrids requiring 2 sprayings in normal years, one before flowering 

 and one after ; and requiring additional application in years favourable to 

 mildew; Couderc- Baronne 4, 151, 156; Gaillard 157; Malegue 474-5; 

 Peage 5-10, 517 ; Seibel 2653, 2655, 2686, 4111, 4151, 4271, 4433. 4461, 

 4591, 4615, 4636, 4662, 4716, 4767, 4951, 4969, 4973, 4989, 5061. 



T}\ Hybrids requiring nearly as many sprayings as the Vinifera : Ma- 

 legue 469-9, Seibel 4616, 4968, 4991, 4999, 5001. 



II. — ■ Ci<assipication according to the intensity of coIvOur of 

 THE must: 



i) Hybrids tmth pink or light red must : Couderc 202-75, Seibel 1000, 

 2859. 



2) Hybrids with ordinary red must : Couderc 7120, 132-11, 162-97, 

 363-N, Seibel i, 4271, 4268, 4643, Malegue 829-6, Berthille-Seyve 618, 822. 



3) " Teinturier " hybrids, with dark red must : Couderc 106-46 (demi- 

 teinturier); Seibel 128-2007, 2660, 4499; Berthille-Seyve 872-1129. 



III. — Classification of hybrids according to the nature of 

 THE SOIE IN WHICH THEY SEEM TO THRIVE BEST (the limestone factor is disre- 

 garded in this classification : in limestone soils grafting must be resorted 

 to for hybrids not possessing sufficient resistance to chlorosis) : 



A) Dry Soils. — Can be planted out freely : 

 i) Tst period black grape : Couderc 202-75 Seibel 1000, 2859, 4643, 

 Berthille-Seyve 872, 11 29. 



2) 2nd period black grape : Couderc 162-97. 



3) Black grape, end of 2nd or ^rd period of ripening : Couderc 7120, 

 132-11, Berthille-Seyve 822, Seibel 4271.
