258 SUGAR BEET SEED. 



that the root is kept for seeding purposes. This, com- 

 bined with the genealogical tables of selected beets 

 during a period of years, has allowed the production of 

 the very superior seed as now furnished by this pro- 

 ducer. About 1700 acres are annually devoted to seed 

 growing, the farms being very far apart, one in the 

 southern part of Russia. Climatic conditions in that 

 section are said to be such that the beets resulting from 

 such seed mature very early, and are very rich in sugar. 

 The two types are the Vilmorin Amelioree and Klein- 

 Wanzleben. The first mentioned are known as mark 



0, very hard skin, short leaves, very fine. The mark 



1, the second mentioned, has in some respects the 

 advantage of the first, while the skin is hard. It has 

 entirely a different characteristic; the leaves remain 

 adhering to the beet late in August, and even until 

 early September.

The main eiifort of these growers is to create a 

 typical beet of high sugar percentage and satisfactory 

 yield, and which will be possessed of certain staying 

 qualities, which will be affected only to a limited 

 extent by atavism. Schreiber & Son are sugar manu- 

 facturers as well as growers; their laboratories for 

 selection are at Heringen. The grandmothers should, 

 in theory, weigh about one pound (400 to 500 grams) 

 and contain from 17.6 to 18.5 per cent, sugar, but from 

 a practical standpoint it is found that two pounds is a 

 better weight and the sugar percentage limit 15.10 to 

 jy — the final selection being made by the alcohol proc- 

 ess. The number of polarizations has also reached a 

 considerable sum, 46,000 of the Schreiber Original, 

 49,700 Schreiber Klein-Wanzleben Amelioree and 

 5000 of the Specialite Riche; the total by alcohol 

 method, 28,800. These analyses showed that 22,000 

 contained more than 17 per cent, sugar of the Original,
