Instructions for the management and reporting of results for wheat program international yield and screening nurseries

The objectives of CIMMYT yield nurseries are: ( 1) to provide research workers who are developing new varieties with an opportunity to assess the performance of their advanced breeding lines over a wide range of climatic, cultural, and disease conditions, (2) to serve as a source of information on adaptation, (3) to allow local research and extension workers to compare the performance of new varieties from other countries, and ( 4) to provide a source of new and valuable genetic variability which cooperators may use directly or in crosses within their breeding programs. The results of the international yield nurseries are statistically analyzed and published for general distribution. The value of these nurseries depends to a large extent on the quality of the data returned for analysis. Therefore, is important for cooperators to study carefully the following pages which contain directions for the conduct of various nurseries and note-taking techniques. Any country collaborating ii} these tests is free to use any of the material included in the nurseries, either as parental material or as commercial varieties. If material from the nurseries is released directly as a commercial variety, the originating institution must be recognized, as well as the country of origin. Varieties originated from these nurseries and released for commercial production cannot be protected under patents or plant breeders' rights legislation. These tests are a collective endeavor, and CIMMYT sincerely requests the cooperation of all interested persons or institutions. Success depends upon the information collectively contributed. It is recognized that there may be faults and limitations in the nursery system as currently established and any suggestions for improvement would be appreciated.
