A Tetraploid, Self-compatible Goji Berry (Lycium chinense Miller) Cultivar, ‘Whasu’, Adaptable to Rain Shelter Greenhouse

The Goji berry line CBP06419-243 was selected from the hybrids (F1) between CBP03310-250 (IT232705) and CBP05399-1. Theline used for crossing was tetraploid induced by the colchicine treatment on bud. Preliminary yield tests using this line were performed from2009 to 2011, and the final selected line was named ‘Cheongyang 18’, which was subsequently registered under the name ‘Whasu’ in 2015. The specific characteristics of this cultivar are summarized as follows: The flowers are distinctly larger, fruit is medium in size, long oblong,and red, and flowering commenced on June 21. Branching by pruning generated less than the reference variety Cheongmyeong. The leafinfection rates by Eriophyes macrodonis Keifer were as high as 7.7%. Anthracnose on fruits in open field was slightly more severe comparedwith the reference cultivar, but the infection rates in rain shelter greenhouses was similar. The content of betaine and free sugar in dry fruitwas higher than that of the reference cultivar. The dry-fruit yield decreased about 13% in open field, but increased 18% in rain shelter greenhouses. The cultivar ‘Whasu’ is suitable for cultivation in rain shelter greenhouses because of self-compatibility and high yield. It is not necessarythe companion cultivar (Registration No. 6345).
