3.3. Detailed effects of the experimental factors as illustrated with RGRA (our proxy trait for performance)
RGRA across cultivation status: wild, feral and cultivated
The relative effect of drought on RGRA was rather similar across cultivation status (Table 4), hence confirming the finding in Table 4 (no significant main effect and interaction effects for cultivation status on RGRA). In absolute terms, under ample-water conditions, wild genotypes had the highest RGRA which was significant, but only modestly, (5.7 %) higher than the lowest RGRA, which was observed among the cultivated genotypes (Table 4). Under restricted-water treatment, wild genotypes still had the highest RGRA which was 5 % higher than the lowest RGRA observed among feral genotypes (Table 4).
