Abstract
The new Chinese matrimony vine line, CB04340-64 was selected from the hybrids(F1) between CB02214-131 (IT232701) and Cheongyang 7 (IT232601) in 2004 to breed the cultivar with high quality and yielding. Its preliminary yield tests were performed from 2006 to 2008 and the selected line was named Cheongyang 14. Its regional yield trial was carried out in Cheongyang, Yesan and Jindo from 2009 to 2011 and Cheongyang 14 was registered as the new variety, ‘Cheongkwang’ in 2011. The specific characteristics were summarized as follows; The leaf was ellipsoidal and small size. The fruit type was oblong and middle size. The flowering time was June 26 with medium flowering. The branching by twice pruning was generated a lot more than the check variety, Cheongun. The resistances to anthracnose and eriophyidae mite were similar to that of the check variety. The content of betaine of dried-fruit and brix degree of fresh fruit were higher than that of the check. The dried-fruit yield was increased about 15 percent in preliminary yield tests and 6 percent regional yield trials. This variety has self-incompatibility. So, the companion variety, Cheongmyeong, was required as pollinizer. (Certificate on grant of plant variety rights: Grant number No.4794, Protection Period 10/02/2014∼09/02/2034).
