INTRODUCTORY STATEMENT 



This inventory, No. 125, is a record of plant material received by 

 the Division of Plant Exploration and Introduction from October 1 

 to December 31, 1935 (Nos. 112307 to 113512). 



Particular mention should be made of the introduction from 

 Oceania of 143 lots of sugarcane cuttings (Nos. 112861 to 113003). 

 These were collected by E. W. Brandes, Bureau of Plant Industry, 

 and represent distinct native strains developed in New Caledonia, New 

 Hebrides, and other Pacific islands. This introduction is a continu- 

 ation of a worldwide search for mosaic-resistant varieties that already 

 has made possible the development of superior commercial varieties 

 for Louisiana and western Puerto Rico, and in the past few years 

 it has increased sugar production for those areas from 46,000 tons 

 to about 500,000 tons per year. 



A closely related project is one concerned with the genetics of the 

 sugar beet. Additional source material for this project is recorded 

 in the introduction through G. H. Coons, of the Bureau of Plant 

 Industry, of 193 lots of beet varieties (Beta spp. ; Nos. 112398 to 

 112590) from Portugal, Germany, and other parts of continental 

 Europe, and from the Canary and Madeira Islands. 



Several lots of seeds of cultivated tobacco were received from 

 Colombia, where Raymond Stadelman of the Bureau of Plant In- 

 dustry was engaged in collecting as many as possible of the local 

 strains grown in the more isolated parts of that country. At the same 

 time W. A. Archer, mentioned in the preceding inventory, continued 

 to send in seed of tobacco varieties from Mexico. These introductions 

 are intended, as has already been pointed out in Inventory No. 124, 

 for the use of Department pathologists seeking to develop disease- 

 resistant tobacco varieties for the United States.
