Synthesis of the impact of diversity on yield and its components.

Stress: ↓ significant negative effect of the stress. F and HE-QTL: significant associations with the allelic frequency or the diversity. Global effect: + (resp. -) reports a significant excess of SNP whose diversity had a positive (resp. negative) effect on the trait. Stress gradient hypothesis: “Yes” if the number of SNPs that have positive impact of their diversity in the traits under CWD is significantly more than the number under R, “No” in the reverse case, ns: non-significant.
