Oat lines (102 total) grown in 1989 and 1990 were analyzed for beta-glucan by flow injection analysis (FIA) to determine the influence of variety and growing season on beta-glucan contents. The correlation between FIA and the AACC enzymatic method for measuring beta-glucan content was 0.97. The average coefficient of variation for the FIA measurements per sample was 1.2% and the oat lines showed a normal distribution for beta-glucan contents in both years, ranging from 3.0 to 6.5% in 1989 and from 3.9 to 6.4% in 1990. Mean beta-glucan contents for the two years were the same, 5.1%, but oat varieties differed significantly, even when tested via the mean square for year X variety.
