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

To breed a Gogi Berry cultivar with high quality and high yield, CBP14639-56, asa 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 conductedto investigate yield characteristics during 2016 to 2017 and the selected line wasnamed Cheongyang No. 34. The regional yield trials of Cheongyang No. 34 were performedat Cheongyang, Yesan and Geumsan areas during 2018 to 2020. As a result, CheongyangNo. 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 andround-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 comparativevariety, ‘Cheongmyeong’. The resistance against gall mite (Eriophyes spp.) wasstronger. The content of betaine, the indicator component, was similar to the comparativevariety, and the dried-fruit yield increased by 41% compared to ‘Cheongmyeong’ in the regionalyield trials. The Gogi Berry ‘Hwaseon’ is a Self-compatibility variety that does notrequire 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 insectsuch as honeybees due to climate change and a decrease in high-temperature activity(Registration No. 9181).
