    Previously published empirical models of U.S. farmland prices are reviewed and reestimated including recent data. It is apparent that structural changes have occurred. A simple single equation econometric model with less economic structure appears to forecast better than a simultaneous equation model. Finally, Box-Jenkins forecasts are roughly as good as those based upon a simultaneous equation econometric model, but somewhat inferior to the single equation model. The results suggest that further research may be needed to explain recent movements of farmland prices.

    Emphasis has been placed on the screening of hybrid selections for resistance to rust, anthracnose, BCMV and Empoasca sp., yield and sensitivity to photoperiod. A total of 1464 materials (937 selections from the breeding program) were screened in the Bean Team Nursery and 700 (200 breeding selections) in the Preliminary Yield Trial. Results from the latter demonstrated major gains in yield among colored materials and a very high proportion of lines resistant to BCMV. Many lines demonstrated multiple-disease resistance.
