Abstract

Dry wt, total oil and fatty acid composition of the oil was determined during kernel development of three maize inbreds. There was significant variability among these inbreds for duration and rate of dry wt, oil and fatty acid accumulation. Relative quantities of the component fatty acids changed as the kernels developed. Palmitic and linolenic decreased while oleic and stearic increased with maturity. Inbred C103, the higher oil inbred, appeared to accumulate oil over a longer period of time while inbred Hy2, the lower oil inbred, accumulated oil over a shorter period of time. However, the latter had higher daily rates of synthesis for some of the unsaturated fatty acids.
