Correlation coefficients for the reference analyses results of the parameters seed oil content, linoleic and oleic acid content, fraction of seed hull and empty seeds of 146 safflower seed samples and direct and indirect effects on oil content

Trait	Direct effect on oil content	Total indirect effects	Correlation coefficients
			Oil content	Linoleic acid	Oleic acid	Seed hull
Linoleic acid	1.438	−0.935	0.503**
Oleic acid	0.452	−0.823	−0.371**	−0.826**
Seed hull	−1.601	0.769	−0.832**	−0.455**	0.348**
Empty seeds	−1.593	0.891	−0.702**	−0.391**	0.308**	0.892**

The probability level is ** for P = 0.01
