INTRODUCTORY STATEMENT 



When the first Inventory of Seeds and Plants Imported was prepared in 1898, 

 there were practically no government plant-breeding institutions in existence, 

 and almost all of the plants introduced were for direct trial as new crops. Few 

 wild forms were represented, and almost no collections of seeds which were the 

 result of the hybridization or selection work of foreign plant breeders. To-day, 

 as is particularly evident in this inventory, an exchange between the plant 

 breeders of the world is going on which shows a remarkable activity in this field. 

 This practice should be encouraged, for it opens up a wide field of trial for any 

 new variety, and it can be confidently predicted that out of these newly made and 

 plastic forms are likely to come many great commercial varieties of the future. 

 Forms which in the country of their origin have proved inferior to others may 

 prove superior in some other environment. 



This inventory contains a record of many selected and previously studied 

 varieties of plants sent by foreign plant-breeding institutions: A collection of 

 peanut varieties from the Department of Agriculture at Buitenzorg, Java {Arachis 

 hypogaea; Nos. 56842 to 56849); a new strain of red clover from Dr. H. N. 

 Knudsen's selection station in Denmark (Trifolium pratense; No. 56850); two 

 new Hungarian wheats, one a selection of the famous Canadian Marquis wheat 

 originated by Charles Saunders {Triticum aestivum; Nos. 56858 and 56859); 

 a new oat from Dr. R. J. Mansholt, of the Royal Netherlands College of Agri- 

 culture {Avena sativa; No. 56892); three new strains of red clover from Dr. G. 

 Martinet, of the Seed-Control Station, Lausanne, Switzerland {Trifolium pra- 

 tense; Nos. 56896 to 56898) ; two recently evolved varieties of oats from the Svalof 

 Seed-Breeding Station of Sweden {Avena sativa; Nos. 56899 and 56900) ; eight 

 selected potato strains resistant to disease from the station for potato culture 

 of Czechoslovakia {Solanum tuberosum; Nos. 56912 to 56919); over 200 selected 

 seedlings of the sweetpotato (which seldom seeds in the United States) from 

 J. B. Thompson, of the experiment station of the Virgin Islands {Ipomoea batatas; 

 Nos. 56920 to 57012, 57395 to 57514) ; a collection of 22 varieties of barley from 

 the Cambridge School of Agriculture, England (Hordeum spp.; Nos. 57013 to 

 57034) ; a hardy variety of red clover selected by Doctor Knudsen, of the Danish 

 Royal Agricultural Society {Trifolium pratense; No. 57036); a large collection of

 Breeding, Tinis, Transcaucasia (Nos. 57094 to 57210); a collection of clover 

 varieties from Prof. N. I. Vavilov, of Petrograd {Trifolium spp.; Nos. 57229 

 to 57247) ; 12 strains of cotton, including the American Pima variety after 

 being grown three generations in Egypt, from Dr. R. H. Forbes, formerly of 

 Arizona {Gossypium spp.; Nos. 57248 to 57259); and a collection of grass and 

 cereal varieties from the Russian experiment station of Ekaterinoslav (Nos. 

 57515 to 57611).
