5. Conclusions
- While the CCPs were capable of levelling out the effects of differing seed sizes on final yield and protein content through yield component parameters when environmental conditions were less stressful in 2013/14, this was not the case during the drought in 2014/15. Thus, for stringent comparisons of genotype-environment interactions, differences between the CCP entries and generations due to differing seed weight at sowing should be avoided, e.g., by a round of seed reproduction in a common environment before future experiments. This will ensure that only genetic differences between entries are reported.
- The similarity in performance of the cycling and non-cycling populations and the high trait profile plasticity in their response to environmental conditions demonstrate the value of well-designed heterogeneous populations in the face of unpredictable environmental conditions. The CCPs were more climate resilient and better able to buffer environmental stress than the pure-line reference varieties, resulting in a lower yield reduction under drought stress.
- Constantly changing environmental conditions did not confer obvious agronomic advantages or disadvantages to the cycling CCPs, highlighting the buffering capacity of intraspecific diversity and confirming the research by Patel et al. [31] that large environmental variance results in slow population evolution. This is of interest to farmers who want to cultivate EPs but do not want to produce their own seed, relying rather on regionally decentralised certified seed production, which should not affect EP performance.
- In contrast, continuously applying differential selection environments for only five to eight years can lead to significant changes. Thus, the increased number of awned ears in the Hungarian home population, as well as the slightly higher susceptibility to stripe rust, fit the overall more continental environmental conditions with colder winters and lower precipitation in Hungary.
- Overall, EPs show great potential in terms of agronomic performance, particularly under conditions where higher biotic and abiotic pressures exist. Decentralised development of such populations allows for the dynamic maintenance of intra-specific diversity with high plasticity. In addition to providing an interesting alternative to genetically homogeneous varieties, it can contribute to the development of future genetic resources.
