| Abstract:
The habitat of wild Japanese iris, Iris ensata Thunb. includes the Korean Peninsula, north-eastern China, eastern Russia and the Japanese Islands. This species is known as an ancestral plant of the garden cultivar called ‘Hana-syoubu’ in Japan. ‘Hana-syoubu’ is one of the most important horticultural plants in the rainy season (June to July in Japan). However, there are no formal descriptions of this species available. Thus, genetic variations in the perianth of this wild Iris were investigated morphologically. The perianth color of wild Japanese Iris varied from pale to dark-red purple. Many varieties of the ‘Bitone’ types were found in which distribution of pigments are completely different between the inner and outer perianth, and semi- or double flowered were found. These characteristics are the same as those found in garden irises; therefore, wild I. ensata may have some useful source for ‘Hana-syoubu’ plant breeders. Plants from the Hokkaido of Japan may provide additional traits to the ‘gene-pool’ of this species. It is really unclear what the authors are attempting to do in the abstract. Are they attempting to describe the genetic basis for observed morphological variations in wild Iris ensata? If so, this should be stated directly. | |
