Table 1.

Parental values, ranges and heritabilities in the AI-RILs of scopolin and scopoletin content (relative values ^a )

	Parents		AI-RIL
Trait	Col-0 value a	Est-1 value a	Range	Mean	Heritability d
Scopolin (H-) b	9.71	28.45	1.9-45.13	19.84	0.50
Scopoletin (H+) c	14.58	34.53	7.82-54.93	29.68	0.45

^aRelative levels measured as an area% of total chromatogram signals (as described in Methods section).

^bContent of scopolin before enzymatic hydrolysis.

^cContent of scopoletin after enzymatic hydrolysis.

^dMeasure of total phenotypic variance attributable to genetic differences among genotypes (broad sense heritability) calculated as V _G  /(V _G  + V _E ).
