IMPROVEMENT
OF VEGETABLE CROPS—
VICTOR R. BOSWELL, Principal Horticulturist, Division of Fruit and Vegetable Crops and Diseases, Bureau of Plant Industry, from survey data submitted by domestic and foreign investigators
The appendix to these articles on vegetable improvement consists of four tabulations of information as follows:
The data in these tabulations and summaries were obtained through a questionnaire sent to all vegetable crop research agencies in this country and to a large number in other lands. The writers of the present articles are grateful for the generous help of their fellow workers, both here and abroad, in making this compilation possible. Despite the great amount of data submitted and the generous response to our requests, it is known that these appended tables do not contain all of the data that could well be included. Some of the workers interrogated were perhaps too modest to list certain cultures as being important or of interest to others; others were admittedly too pressed by other matters to prepare a detailed list of their material and activities. But even though the data are incomplete, the reader will find clues to nearly every kind of vegetable- breeding material that is available and leads to the numerous investigators who are engaged with the hundreds of breeding and improvement problems that are receiving attention today.
The writers hoped that it would be possible to include similar tables of information relating to private work by commercial seedsmen. The immensity of the task of determining the origin of the hundreds of varieties made it impossible. A few commercial firms keep rather complete records of the parentage and dates of their introductions, but most do not. The major role that has been played by private agencies has been repeatedly referred to in these articles, and acknowledgment made to individuals and firms wherever pertinent information could be included. It should thus be clear to all that no discrimination is intended by the omission of more extensive data on commercial contributions. Unfortunately, justice cannot be done to such a task within the space available here.

Union of Soviet Socialist Republics | Tomato | Breeding for resistance to wilt |
---------- | Unfortunately, up-to-date information from plant breeders in the Union of Soviet Socialist Republics could not be obtained in time for including in this report, but it should be pointed out that they are among the most active workers in the field today. Special emphasis has been placed on thorough exploration of all promising parts of the world for obtaining varieties and breeding material of value. Very extensive programs are in progress at numerous locations for studying introduced materials in detail and for large-scale hybridization and selection work. Large resources and great energy are being devoted to this work. There is no doubt that results of considerable practical and scientific importance are being obtained. |
