| We have tested most of the World Wheat Collection and have been testing
the International Spring Wheat, Oats and Barley Rust Nurseries, as well
as the F.A.O. wheat nursery, for many years (reported elsewhere). Many large
and small collections from individuals and institutions have also been tested.
In addition to rust records, we have a certain amount of agronomic data
for some of the tested material. If any of the reported lines or varieties
appear useful to our readers, we will be happy to supply seed, further information
or suggest where seed is available. Comments and criticisms on the usefulness
of this work would be appreciated. In order to continue the present scope of this work, may we issue another call for new wheats to test for stem rust resistance in particular. The types of material that could be useful are: 1. Lines and varieties used in crossing programs. 2. Lines from breeding programs; segregating or advanced generations or bulks of early generations. 3. New releases and the ones that didn't quite make it. 4. Interspecific or intergeneric derivatives. 5. New material from mutation breeding work. In addition to wheat, we would also appreciate receiving small samples of oats and barley lines and varieties falling into the above categories. Acknowledgements The continued support of the Rockefeller Foundation is gratefully acknowledged. Special thanks are due to all donors of collections of material for testing. We appreciate the efforts of the Pathology section of this station, Dr. E. J. GUTHRIE, Mr. N. K. PATEL and staff. We appreciate the efforts of Mr. V. P. PATEL and our field assistants who did the plot work and much of the recording. |
