An additional experiment was made with two varieties of Capsicum annuum L. to ascertain the possibility of obtaining graft hybrids by means of successive grafting. The diagnostic character of the fruit shape in Spanish Paprika, which was used as the stock plants, appeared in several fruits formed on the scion plant, Yatsubusa, which had been successively grafted on Spanish Paprika for three generations. This character was transmitted to the first and second self-bred generations. The rate of occurrence of transformed fruits in the progeny obtained through successive grafting was much higher than that found in the first and second generations of the plant which was grafted for only one generation. Discussion was made on the cause of hereditary transformation observed in a series of grafting experiments. The author wishes to express his cordinal thanks to Prof. K. Fukumoto for his helpful advice throughout the experiments, and also to Dr. K. Hayashi, Professor of Tokyo University of Education, for his help in preparing the manuscript. [AS]
