The lines studied differed in ribonuclease content, and the hybrids were intermediate, but closer to the female parent. The endosperm, scutellum, roots and shoots had the same number of major isozymes both in the parents and in the hybrids. The parental lines differed in the minor isozymes in the scutellum and roots. The isozyme pattern in the roots of the hybrids contained the components of the male and female parents, but no new isozymes specific to the hybrids.
