Evaluation of the Productive Potential of a World Collection of Chickpeas (Cicer arietinum L.) for the Initiation of Breeding Programs for Adaptation to Conservation Agriculture

Transitioning to conservation agriculture is proving to be a better alternative and could become the norm in the future. Morocco, geographically located in a hot spot, is much more vulnerable to the hazards of climate change and the advantages of conservation agriculture remain a good compromise to ensure sustainable agricultural production. However, the lack of sufficient knowledge about this agricultural technology could be a hindrance and thus create mistrust among farmers. Therefore, the objective of our study is to evaluate the performance of a collection of chickpeas in each tillage system to identify genotypes that can be integrated into breeding programs for adaptation to conservation agriculture. Our study shows no significant effect of tillage on grain yield. Chlorophyll content and pod number made the strongest direct and positive contributions to yield for conventional and no-till, respectively. Nine genotypes including two checks (C1 and C2) were selected in both systems through MGIDI (multi-trait genotype–ideotype distance index) analysis. These genotypes would be potential candidates for breeding programs for adaptation to no-till because of their plasticity to reproduce acceptable yields in both till systems.
