Kernels were collected from three maize (Zea inrays L.) inbreds from 10 days after pollination until kernel maturity. Sitosterol, campesterol, and stigmasterol were the major sterols at all stages of kernel development. Cholesterol was less than 1 % of the dry weight. The three major sterols accumulated during kernel development, but at a rate slower than dry weight. 10,14, 18, 22, 26, 30, 34, 38, 42, 50, and 60 DAP2 and
