Three grain hybrids and their parents were compared until 40 days after emergence. Heterosis (advantage of the hybrid over the better parent) was significant in all hybrids for length of the seminal root, growth rate of adventitious roots and root volume. Heterosis for root volume was probably a result of increased number and improved growth of lateral root branches. Consistent heterosis was not apparent for number of adventitious roots per plant, nor for seminal or adventitious root dry matter.
