N2  - The 23rd International Bread Wheat Screening Nursery (IBWSN) consisted of a group of 197 high yielding, advanced bread wheat lines (including five long-term checks) selected out of approximately 1000 lines. This subsequent report is presented for the quick appraisal and utilization of data by cooperators in their breeding programs. Ninety-six cooperators from 47 countries returned data in time to be included in this report (Table 1). The choice of  variables rest with the individual cooperator. In this summary, we report the major variables. The number of observations differs among variables and the means over locations are given by entry in Table 2. Hopefully, these lines will enrich the germplasm base of our cooperators. Use the Table of Contents as a quick reference to the information provided in this report
