2o6 SUGAR BEET SKED. 



Austrian varieties, they came out first. The starting 

 point in the Janasz selection is the creation of families 

 having a common parent; on the field it is possible to 

 determine the value of each family as regards yield and 

 sugar percentage from these. In the autumn 60,000 to 

 100,000 roots are selected; their analyses in the labor- 

 atory are made the following February, they being 

 kept in silos, with necks upward, in one layer. 

 There then follows a second selection from exterior 

 appearance of the roots; there is at least 40 per cent, 

 of the total then thrown out. The Keil rasp is used 

 for sampling. There is a slight modification of the 

 Pellet cold-water method; to a given weight of pulp 

 is added a known volume of water. Filtration and 

 polarization follow in a regular way. It is claimed 

 that most accurate results have been obtained. For 

 mixing water of known volume with weighed pulp, 

 special glasses are used. The classification of the beets 

 for mothers does not end with their analysis, as they 

 have to undergo another severe classification as to 

 weight, shape, etc., followed by other analyses by alco- 

 hol digestion. Not more than 5 to 8 per cent, of all 

 beets examined come under the head of Class. I, from 

 which, in two years, are obtained mothers of special 

 selection. About 70 per cent, of the beets examined in 

 the laboratory form the Class II. 



The silos for these mothers of Class II consist of 

 several layers of roots separated by a suitable layer of 

 earth, in the middle of which is a layer of straw. These 

 roots are planted at a distance of 60 c. m. (23.4 inches), 

 the soil being constantly worked by cultivator and 

 spade. The seeds and stalks, when harvested, are tied 

 up in bundles and allowed to dry for two weeks on the 

 field; the separation of seed from stalks is done by a 

 steam threshing machine. The Janasz company do a 

 very little advertising and most of the crop finds its way 

 to Russian Poland. The work is known as C. C.-or
