Abstract
Normal and opaque‐2 kernels from segregating maize (Zea mays L.) ears were examined for kernel components, oil content, and fatty acid composition. Normal kernels were higher in kernel and endosperm weight and embryo oil concentration, and lower in embryo weight than opaque‐2 kernels. Compared to normal, the oil from opaque‐2 kernels was slightly but significantly higher in oleic acid and lower in linoleic acid composition. Comparison of normal and floury‐2 kernels from segregating ears showed kernel and endosperm weights of the normal kernels were greater than for floury‐2, and embryo weight was similar. In a comparison of near‐isogenic floury‐2 and normal single‐cross hybrids, the kernel components were heavier in normal, while percent oil was greater for floury‐2 owing largely to a greater proportion of embryo. Percent oil in embryo was less in floury‐2 hybrids.
