Within each treatment, letters indicate significant differences between genotypes at p < 0.5. *, ** and *** are significant at p < 0.05, p < 0.01 and p < 0.001, respectively. ‘ns’ means insignificant at p < 0.05. Values in bold indicate significance (p < 0.05). HYG: High-yielding genotypes (grey shadowed), LYG: Low-yielding genotypes, G: Genotype, T: Treatment.
