Connecting variety trialling systems across two countries
Connecting variety trialling systems across two countries
Abstract (English)
In Europe, before acceptance to a country's national list, crop variety candidates must undergo testing for value for cultivation and use (VCU) in multi‐environment trials. Once a variety is accepted to the national list of a country, it can be marketed in that county. Moreover, it may be marketed in other European countries as well, even if it has not been tested for VCU, and hence, there is no performance assessment in those other countries. This paper investigates how VCU trialling systems of two countries can be connected and integrated so that performance can be assessed for both countries without altering the capacity of the trialling systems. Our statistical calculations based on VCU trial data for maize from Germany and Poland highlight the benefit of a joint analysis of data from two countries. Moreover, we show how the efficiency of each country's VCU testing system can be improved—without altering the overall capacity of the systems in terms of the number of trials and the number of plots per trial—by ensuring that each variety is tested in both countries.
