Two studies, one with four cultivars grown at four locations during 19
89 to 1993, and the second with a transgenic and its non-transformed p
arent cultivar grown at three locations for three years, were undertak
en to explore the variation in total flavonoid content of flaxseed (Li
num usitatissimum). Results of the analyses of variance for the first
study showed significant cultivar as well as environmental effect on f
lavonoid content. Cultivar NorLin displayed the highest flavonoid cont
ent across the sites with a mean of 71 mg/100 g, and Omega, a yellow-s
eeded flaxseed cultivar, the lowest with a mean of 35 mg/100 g. There
was no significant difference between a transgenic flaxseed and its no
n-transformed parent for total flavonoid content except for one locati
on in 1991. Flavonoid content was inversely related to the protein con
tent and there was a weak positive correlation between flavonoid and o
il levels.
