INTRODUCTORY STATEMENT 



This inventory, No. 133, records the plant material (Nos. 124969 to 

 126493) received by the Division of Plant Exploration and Introduc- 

 tion during the period October 1 to December 31, 1937. 



With the definite purpose of studying wild tomato material in the 

 field and of collecting whatever was available, particularly from plants 

 believed to be truly wild, Dr. H. L. Blood, of the Utah Agricultural 

 Experiment Station, and cooperating with the Division of Fruit and 

 Vegetable Crops and Diseases, Bureau of Plant Industry, spent the 

 last 2 months of 1937 in Peru, Bolivia, northern Argentina, and Chile, 

 collecting not only this type of material but also cultivated tomatoes 

 from native markets. 



In addition to true tomatoes, he gathered seeds of various other non- 

 tuberous solanaceous plants, including species of Cyphomandra, 

 Nicandra, Physalis, and Solanum, which have been added to the work- 

 ing material of Department pathologists. 



Since that time, many of his collections have been studied taxo- 

 nomically and reported by C. H. Muller (Miscellaneous Publication 

 No. 382, A Revision of the Genus Lycopersicon, July 1940) ; these 

 include one new species, one new variety, and three new forms. 



Pathologists have already published on the unusual characteristics 

 of one of the wild tomatoes, Lycopersicon hirsutism, found by Dr. 

 Blood. It is stated (Phytopathology 29 : 757-759, 1939) that while 

 making crosses between this wild species and the common tomato the 

 discovery was made that L. hirsutism is apparently completely toler- 

 ant to tobacco mosaic and extremely resistant to fusarium wilt. 



Contrary to many suppositions, Afghanistan is not entirely inacces- 

 sible if one may judge by the more than 900 introductions in this pres- 

 ent inventory that are credited to the Bureau's agricultural explorer
