Summary
Anthocyanins of colchicine-induced amphidiploids of I. laevigata × I. ensata were analyzed by the HPLC procedure and compared with those of parental species and F1 hybrids of I. laevigata × I. ensata. The amphidiploids were characterized by seventeen anthocyanins, and exhibited all anthocyanins of the parental species and the F1 hybrids. Malvidin 3RGac5G and petunidin 3RGac5G in anthocyanins detected were major pigments in the amphidiploids, which exhibited strongly the malvidin 3RGac5G-petunidin 3RGac5G type of I. ensata rather than the petunidin 3RGac5G-malvidin 3RGac5G type of I. laevigata. Moreover, a higher degree of anthocyanin content was observed in the amphidiploids and the F1 hybrids. Namely, the anthocyanin content of the amphidiploids and the F1 hybrids were 2.81 and 2.45 times as much as that of the mid-parent. This implies that there is a complementary effect on anthocyanin synthesis of parental genes in them. Finally, the utility of the amphidiploids was discussed.
