Orange Stocks used in California. 



In a recent letter received by the Chief of the Division of 

 Entomology from Washington the following information, on the 

 authority of Professor A. D. Shamel, is given in regard to the 

 source of the citrus seed used for the production of stock for budding 

 oranges in California. It is to be noted that the kind of stock used 

 almost exclusively, i.e. " sour " stock, has never been a success in 

 South Africa. The paragraph reads: — 



" The source of seed used for orange stocks for citrus in 

 California is primarily the sour orange seed imported into California 

 from Florida. We raise a small quantity of sour stock seed in 

 California, but probably 99 per cent, of this seed used by nurserymen 

 comes from Florida. We are now experimenting with some seed of 

 the Seville orange which we secured from a Canadian marmalade 

 manufacturing establishment which uses imported Spanish Seville 

 oranges for making marmalade. It may be that source of supply 

 will supplant that of Florida, because v^e have had great difficulty 

 during the past year in securing adequate supplies of Florida seed. 

 This condition has resulted in a shortage of stock in California at this 

 time. In the past year about 100 bushels of Florida sour orange 

 seed was received from Florida and planted in California. I 

 remember that one year before the war 1000 bushels of Florida-grown 

 stock seed was planted by citrus nurserymen in southern 

 California."
