Abstract:

This paper reported the discovery process and identification method for the first intersectional hybrid between sect. Moutan and sect. Paeonia in China, which was named after 'He Xie'. According to observation and comparison on morphology of sect. Moutan, sect. Paeonia and 'He Xie', the morphology of 'He Xie' had the features similar to both herbaceous peony and tree peony, but more similar to herbaceous peony; Using SRAP (Sequence-related amplified polymorphism) molecular marker technique, the results revealed that the amplified fragments respectively unique to sect. Moutan and sect. Paeonia showed additivity in 'He Xie', which proved that it was could be the hybrid of the both section. 'He Xie' was proposed to be perennial herb by intersectional hybridization between the two sections identified from the aspects of morphology and molecular biology.

Key words: Tree peony, Herbaceous peony, Intersectional hybrid, Itoh Hybrid, SRAP
