Abstract The characteristics of autoallotetraploid hybrids obtained from the cross between Iris ensata cv. Raspberry Rimmed (4X) and amphidiploids of I. laevigata × I. ensata were examined and compared with those of their parents. The color of inner and outer perianths in the autoallotetraploids were bluish purple and similar to those of the amphidiploid parent. However, the autoallotetraploids exhibited low pollen fertility. In addition, the autoallotetraploids were characterized by 17 or 19 anthocyanins and had high resemblance to their parents in the anthocyanin expression. Among these anthocyanins, malvidin 3RGac5G and petunidin 3RGac5G were regarded as major anthocyanins in the autoallotetraploids and their parents, but the differences in the ratios of malvidin 3RGac5G:petunidin 3RGac5G between the autoallotetraploids and their parents were ca. 2:1 for the former and ca. 1:1 for the latter. No viable hybrid seeds were obtained from the reciprocal crosses between I. ensata (2X and 4X) and the autoallotetraploids. Finally, the interspecific cross-breeding of I. ensata using the autoallotetraploids is discussed.
