Yield and yield components of several bread wheat genotypes: toward adaptation to different environments

In the current context of climate change, marked by severe drought and heat stresses, we hypothesized that the trait plasticity, opposite of stability, could be an important mechanism of reaching adaptability and therefore enhancing resilience. To assess this, we tested 10 promising genotypes under three environments (E1, E2, and E3) for yield and its components: Number of Spikes per m 2 (NS/m 2 ), Number of Spikelets per Spike (NSpk/S), Number of Grains per Spikelet (NG/Spk), Number of Grains per Spike (NG/S), Number of Grains per m 2 (NG/m 2 ); and Thousand Grain Weight (TGW). A highly significant effect (p
