Quantitative inheritance of oil in the corn kernel
1949
Sprague, G.F. | Brimhall, B.
1. The effect of season on variation in oil content of the corn kernel is shown to be small in comparison to the effect of parentage. 2. Data are presented from four crosses between inbreds differing in oil content. Two of the crosses show partial dominance of low-oil content, a third is intermediate, and the fourth cross exhibits some evidence for dominance of high-oil percentage. 3. The relative effects of percentage of germ in the corn kernel and percentage of oil in the germ on the total oil content of the kernel were determined. 4. Inheritance of oil content in a cross between HO and LO, inbreds derived from the Illinois High-Oil and Illinois Low-Oil strains, is discussed with reference to type of gene action and minimum gene numbers involved.
