The above materials shall be analyzed for physiological and agronomic traits (monitoring drought tolerance, growth, yield etc ...) over several years (see Appendix 2) so that the results are meaningful and comparable between different places. These data will then be compared in order to identify the most tolerant hybrids to drought and with characteristics tailored to each soil and climate conditions. Once identified, these plants may be planted in multisite trials on a small or large scale to confirm possible Genotype x Environment interactions. The results of this research will be shared among the participants of the project and will be reported (articles, communications, international conferences).
