| Variety release decisions involve a number of tradeoffs, usually between grower and end-user characteristics as well as significant uncertainties about agronomic, quality, and economic variables. In this study, methodologies were developed to value tradeoffs for grower and end-user characteristics for wheat. The models capture effects of variability in agronomic, quality, and economic variables. The models were applied for three experimental varieties which have since been released and for two hypothetical varieties. Results indicate two of the experimental varieties provide improvements in grower and end-use value over most of the incumbents. Comparison of a risk adjusted portfolio model consisting of characteristics of end-use and grower values... |

| Variety development and release decisions involve tradeoffs between yields and characteristics valued by end-users, as well as uncertainties about agronomic, quality, and economic variables. In this study, methods are developed to determine the value of varieties to growers and end-users including the effects of variability in economic, agronomic, and quality variables. The application is to hard red spring (HRS) wheat, a class of wheat for which these tradeoffs and risks are particularly apparent. Results indicate two experimental varieties provide improvements in grower and end-user value, relative to incumbents. Stochastic dominance techniques and statistical tests are applied to determine efficient sets and robustness of the results. A risk-adjusted... |
