Relative abundance, LD₅₀ value and resistance equivalence of resistance‐related (RR) metabolites identified in barley genotype Chevron.

RR metabolites	Relative abundance of RR metabolites	LD50 value of RR metabolites (mm)	Resistance equivalence*
Pyroglutamic acid	2.33	3.172	0.73
p‐Coumaric acid	3.48	1.154	3.01
Capric acid	1.22	0.1003	12.16
Quinic acid	1.78	3.155	0.56
Ferulic acid	1.97	1.766	1.11
d‐Gluconate	1.58	2.65	0.59
Lauric acid	1.31	2.142	0.61
Sinapate	1.19	1.747	0.68
Naringenin	1.43	1.58	0.9
Kaempferol	1.24	4.768	0.25

^* Resistance equivalence (RE) =[(AR/AS)/LD₅₀], where AR is the abundance of the metabolite in the resistant genotype, AS is the abundance of the metabolite in the susceptible genotype and LD₅₀ is the concentration (mm) of metabolite that inhibited 50% of the biomass of Gibberella zeae. The higher the RE value, the higher the potential resistance.
