"Genotype And Environment Effects On Oat β-glucan Concentration"
Crop Sci. 1991 Volume 31, Issue 6 Pages 1517-1520
D. M. Peterson

Abstract: Oat (Avena sativa L.) and oat bran have beneficial effects as human food and animal feed, including the lowering or serum low-density-lipoprotein (LDL) cholesterol, a risk factor for cardiovascular disease. This effect has been attributed to the high concentration of (1 fwdarw 3) (1 fwdarw 4)-β-D-glucan in oat. To efficiently breed oat cultivars higher in this beneficial constituent, the influence of genotype and environment must first be determined. Twelve cultivars were grown in nine different locations in randomized complete blocks to measure the level and variation in β-glucan concentration. Samples were dehulled, ground, and the β-glucan concentration measured by a flow injection analysis system. Significant differences were found for the main effects of genotype and location and their interaction. The variance ratio for the interaction was much smaller than those for the main effects and, except for one location, the rank order of the cultivars was generally similar. The b-glucan concentration was not correlated with 100-groat weight. It was concluded that selection for high β-glucan in a single environment should be representative of relative performance in other environments.
