‘Hwaseon’, a Tetraploid Gogi Berry (<i>Lycium chinense</i> Miller) Cultivar with Self-compatibility and Resistant to Gall Mite (<i>Eriophyes spp</i>. Keifer)

To breed a Gogi Berry cultivar with high quality and high yield, CBP14639-56, as a Gogi Berry line, was selected from the hybrids(F1) of 'CBP11542-206 (IT345448)' and 'CBP07445-64 (IT258918)'in 2015.The preliminary and the advanced yield were conducted to investigate yield characteristics during 2016 to 2017 and the selected line was named Cheongyang No. 34.The regional yield trials of Cheongyang No. 34 were performed at Cheongyang, Yesan and Geumsan areas during 2018 to 2020.As a result, Cheongyang No. 34 was registered as the new variety, 'Hwaseon'.The specific characteristics of 'Hwaseon' are as follows.The type of tree is half opened shape and leaves are green and round-lanceolate.The observed flowering time is June 18, later than the comparative variety 'Chengmyeong'.The shape of fruits is red, long oval type and a large fruit species.Self-compatibility rate was 71.7%, which was very high compared to 2.8% of the comparative variety, 'Cheongmyeong'.The resistance against gall mite (Eriophyes spp.) was stronger.The content of betaine, the indicator component, was similar to the comparative variety, and the dried-fruit yield increased by 41% compared to 'Cheongmyeong' in the regional yield trials.The Gogi Berry 'Hwaseon' is a Self-compatibility variety that does not require mixing of pollinated varieties, and it is expected to help farmers growing Gogi Berry, who are suffering from low fertilization rates due to the recent decrease pollinating insect such as honeybees due to climate change and a decrease in high-temperature activity (Registration No. 9181).
