Abstract
(1) Paper-chromatographic experiments were carried out in order to determine the kind of anthocyanins, and to clarify their genetical behaviours, using the flowers of amphidiploid and its parents.
(2) Material used were Abelmoschus esculentus (2n=124), A. Manihot (2n=68), F1 (2n=96) of the above two, and“Nori-Asa”(2n=192) which is an artificially raised amphidiploid between them.
(3) The results have shown that the coloring matters in esculentus consist of ilicicyanin, chrysanthemin (or idaein) and cyanidin, and that the pigments in Manihot are delphinidin 3-glucoside (or empetrin) and delphinidin together with all components appearing in esculentus.
(4) The coloring matters in F1 and amphidiploid were found to be identical, in spite of an appreciable difference in their chromosomal constitution. The number of pigment components in these two plants was equal to that of Manihot, but was apparently superior to that of esculentus plant.
